En el mundo de la programación, una
función es una pieza de código que implementa una determinada función.
function(param1,param2,...)
- Composition:
Function name (parameter1, parameter2, ...), may have no parameters or have multiple parameters. For example, ```MA(x,n);``` means to return to the simple moving average of ```x``` within ```n``` periods. Among them, ```MA()``` is a function, ```x``` and ```n``` are the parameters of the function.
When using a function, we need to understand the basic definition of the function, that is, what data can be obtained by calling the function. Generally speaking, functions have parameters. When we pass in parameters, we need to ensure that the incoming data type is consistent. At this stage, the code hinting function of most IDEs is very imperfect. There is a data type of the parameter given, which brings some trouble to our use, and ```MA(x,n);``` is interpreted as:
```
Return to simple moving average
Usage:
AVG:=MA(X,N): N-day simple moving average of X, algorithm (X1+X2+X3+...+Xn)/N, N supports variables
```
This is very unfriendly to beginners, but next, we will dissect the function thoroughly, trying to find a quick way to learn and use the function.
Para aprender funciones rápidamente, necesitamos entender un concepto primero, se llama
// Because it will be used in the following code, the variable return_value is used to receive and save the return value of function()
// retrun_value := function(param1,param2);
// For example:
AVG:=MA(C,10); // AVG is retrun_value, function is MA function, param1 parameter: C is the closing price sequence data, param2 parameter: 10.
En segundo lugar, el segundo concepto importante de la función es el parámetro, y se pueden obtener diferentes valores de retorno al pasar diferentes parámetros.
// The variable ma5 receives the 5-day moving average of closing prices
ma5:=MA(C,5);
// The variable ma10 receives the 10-day moving average of closing prices
ma10:=MA(C,10);

Closing price: C;
Closing price magnified 100 times: TEST(C);
The last closing price is magnified by 100 times: TEST(REF(C, 1)); // When the mouse moves to the K-line of the backtest, the variable value will be prompted
- ```scope```object
The ```scope``` object can add attributes and assign anonymous functions to attributes, and the anonymous function referenced by this attribute can be called in the code part of MyLanguage.
- ```scope.getRefs(obj)```function
In ```JavaScript``` code block, call the ```scope.getRefs(obj)``` function to return the data of the passed in ```obj``` object.
The ```JavaScript``` code wrapped with the following ```%% %%``` will get the ```C``` passed in when the ```TEST(C)``` function in MyLanguage code is called Close price.
The ```scope.getRefs``` function will return all the closing prices of this K-line data. Because of the use of ```throw "stop"``` to interrupt the program, the variable ```arr``` contains the closing price of the first bar only. You can try to delete ```throw "stop"```, it will execute the ```return``` at the end of the ```JavaScript``` code, and return all closing price data.
```
%%
scope.TEST = function(obj){
var arr = scope.getRefs(obj)
Log("arr:", arr)
throw "stop"
return
}
%%
TEST(C);
```
- scope.bars
Access all K-line bars in the ``JavaScript`` code block.
The ```TEST``` function returns a value. 1 is a negative line and 0 is a positive line.
```
%%
scope.TEST = function(){
var bars = scope.bars
return bars[bars.length - 1].Open > bars[bars.length - 1].Close ? 1 : 0 // Only numeric values can be returned
}
%%
arr:TEST;
```
```
# Attention:
# An anonymous function received by TEST, the return value must be a numeric value.
# If the anonymous function has no parameters, it will result in an error when calling TEST, writing VAR:=TEST; and writing VAR:=TEST(); directly.
# TEST in scope.TEST must be uppercase.
```
- scope.bar
In the ```JavaScript``` code block, access the current bar.
Calculate the average of the high opening and low closing prices.
```
%%
scope.TEST = function(){
var bar = scope.bar
var ret = (bar.Open + bar.Close + bar.High + bar.Low) / 4
return ret
}
%%
avg^^TEST;
```
- scope.depth
Access to market depth data (order book).
```
%%
scope.TEST = function(){
Log(scope.depth)
throw "stop" // After printing the depth data once, throw an exception and pause
}
%%
TEST;
```
- scope.symbol
Get the name string of current trading pair.
```
%%
scope.TEST = function(){
Log(scope.symbol)
throw "stop"
}
%%
TEST;
```
- scope.barPos
Get the Bar position of the K-line.
```
%%
scope.TEST = function(){
Log(scope.barPos)
throw "stop"
}
%%
TEST;
```
- scope.get\_locals('name')
This function is used to get the variables in the code section of MyLanguage.
```
V:10;
%%
scope.TEST = function(obj){
return scope.get_locals('V')
}
%%
GET_V:TEST(C);
```
```
# Attention:
# If a variable cannot calculate the data due to insufficient periods, call the scope.get_locals function in the JavaScript code at this time
# When getting this variable, an error will be reported: line:XX - undefined locals A variable name is undefined
```
- scope.canTrade
The ```canTrade``` attribute marks whether the current bar can be traded (whether the current Bar is the last one)
For example, judging that the market data is printed when the strategy is in a state where the order can be traded
```
%%
scope.LOGTICKER = function() {
if(exchange.IO("status") && scope.canTrade){
var ticker = exchange.GetTicker();

```REF(MIN5.C, 1)``` is the K -line period of the current model (the above code backtest period is set to 1 minute, i.e. ```period: 1m``), the closing price of the 5-minute period where the penultimate BAR is located at the current moment.
These two definitions are differentiated, and they can be used as needed.
- ## Mode Description
- ### Signal filtering model of one opening and one leveling
In the model, the ```AUTOFILTER``` function is written to control and realize the signal filtering of one opening and one closing. When there are multiple opening signals that meet the conditions, the first signal is taken as the valid signal, and the same signal on the K-line will be filtered out.
Instructions supported by filtering model: BK, BP, BPK, SK, SP, SPK, CLOSEOUT, etc. Instructions with lot numbers such as BK(5) are not supported.
For example
Los Estados miembros podrán autorizar el uso de las mismas en los casos en que se considere necesario. Los Estados miembros deberán tener en cuenta los siguientes elementos: Las condiciones de los requisitos de seguridad de los sistemas de seguridad de seguridad de los sistemas de seguridad de los sistemas de seguridad de los sistemas de seguridad de los sistemas de seguridad de los sistemas de seguridad de los sistemas de seguridad de los sistemas de seguridad de los sistemas de seguridad de los sistemas de seguridad de los sistemas de seguridad de los sistemas de seguridad de los sistemas de seguridad de los sistemas de seguridad de los sistemas de seguridad de los sistemas de seguridad de los sistemas de seguridad de los sistemas de seguridad de los sistemas de seguridad de los sistemas de seguridad de los sistemas de seguridad de los sistemas de seguridad de los sistemas de seguridad de los sistemas de seguridad de los sistemas de seguridad de los sistemas de seguridad de los sistemas de seguridad de los sistemas de seguridad de los sistemas de seguridad de los sistemas de seguridad de los sistemas de seguridad de los sistemas de seguridad de los sistemas de seguridad de los sistemas de seguridad de los sistemas de seguridad de los sistemas de seguridad de los sistemas de seguridad. Los puntos de referencia de las partidas 1 y 2 se aplicarán a las partidas 2 y 3. C>BKPRICE+10 de diciembre
Comprensión:
Como en el ejemplo anterior, cuando AUTOFILTER no está configurado, la tercera fila BK, la cuarta fila BK y la quinta fila SP se activan en secuencia, y cada línea K activa una señal una vez.
Si el AUTOFILTER está configurado, después de activar BK, solo se activa SP, se ignoran otras señales BK y cada línea K activa una señal una vez.
- ### Increase and decrease position model
The ```AUTOFILTER``` function is not written in the model, allowing continuous opening signals or continuous closing signals, which can increase and decrease positions.
Supported instructions: BK(N), BP(N), SK(N), SP(N), CLOSEOUT, BPK(N), SPK(N), open and close orders without lot size are not supported.
(1)Instruction grouping is supported.
(2)When multiple instruction conditions are satisfied at the same time, the signals are executed in the order in which the conditional statements are written.
For example:
Los Estados miembros podrán autorizar el uso de las mismas en los casos en que se considere necesario. Los Estados miembros deberán tener en cuenta los siguientes elementos: Los datos de las operaciones de los Estados miembros deberán ser publicados en el Diario Oficial de la Unión Europea. Las condiciones de los controles de seguridad se determinarán en función de las condiciones de seguridad establecidas en el anexo II. C>BKPRICE+10 de diciembre
Use ```TRADE\_AGAIN```
It is possible to make the same command line, multiple signals in succession.
Comprensión: El ejemplo anterior se ejecuta uno por uno, y la señal después de la ejecución ya no se activa. Reinicie el estado del modelo después de cerrar la posición. Una línea K activa una señal una vez.
- ### Model with one K-line and one signal
Regardless of whether the K-line is finished, the signal is calculated in real-time orders, that is, the K-line is placed before the order is completed; the K-line is reviewed at the end. If the position direction does not match the signal direction at the end of the K-line, the position will be automatically synchronized.
For example:
Los Estados miembros deberán establecer un sistema de gestión de los recursos humanos para la gestión de los recursos. Los datos de los datos de los Estados miembros se publicarán en el Diario Oficial de la Unión Europea. CROSSUP(MA1,MA2),BPK; //La media móvil de 5 períodos se cruza hacia arriba, y la media móvil de 10 períodos va largo. CROSSDOWN(MA1,MA2),SPK; //La media móvil de 5 períodos se cruza hacia abajo y la media móvil de 10 períodos se queda corta. el sistema de filtro automático;
- ### A model of multiple signals on one K-line
The model uses ```multsig``` to control and implement multiple signals from one K-line.
Regardless of whether the K-line is finished, the signal is calculated in real-time.
The signal is not reviewed, there is no signal disappearance, and the direction of the signal is always consistent with the direction of the position.
If multiple signal conditions are met in one K-line, it can be executed repeatedly.
Por ejemplo: Los Estados miembros podrán autorizar el uso de las mismas en los casos en que se considere necesario. Los Estados miembros deberán tener en cuenta los siguientes elementos: Los puntos de referencia de las partidas 1 y 2 se aplicarán a las partidas 2 y 3. C>BKPRICE+10 de diciembre
```MULTSIG``` can execute multiple command lines within one K-line.
A command line is only signaled once.
O,BK; // Todas estas condiciones se pueden ejecutar en una barra de línea K, pero sólo una señal por línea 10+O,BK; // Estrategia más TRADE_AGAIN(10); puede hacer múltiples señales por línea 20+O,BK; 40+O,BK; Se aplicará el método MULTSIG.
Supplement:
1.The model of adding and reducing positions, two ways of one signal and one K-line: placing an order at the closing price and placing an order at the order price, are both supported.
2.The model of adding and reducing positions also supports ordering of multiple signals from one K-line.
The model of adding and reducing positions, write the ```multsig``` function to realize multiple additions or multiple reductions on one K-line.
- ## Execution mode
![MyLanguage Doc](/upload/asset/28d0c387f293478294600.png)
- ### Bar model
The Bar model refers to the model that is executed after the current BAR is completed, and the trading is executed when the next BAR starts.
- ### Tick model
The Tick model means that the model is executed once for each price movement and trades immediately when there is a signal.
The Tick model ignores the previous day's signal (the previous day's signal is executed immediately on the same day), and the Tick model focuses only on the current market data to determine whether the signal is triggered.
- ## Chart display
- ### Additional indicators for main chart
> Use operator ```^^```, set indicators are displayed on the main chart while assigning values to variables.
MA60^^MA(C, 60); // Calcular el indicador medio con el parámetro de 60
![MyLanguage Doc](/upload/asset/168d6ee1bbb8c7c9be63.png)
- ### Additional Indicators for sub-chart
Use operator ```:```, set indicators are displayed on the sub-chart while assigning values to variables.
ATR:MA(MAX(MAX((HIGH-LOW),ABS(REF(CLOSE,1)-HIGH)),ABS(REF(CLOSE,1)-LOW)),26); // Asignar un valor a la variable ATR, el símbolo
![MyLanguage Doc](/upload/asset/7b032733df1539ff923b539b1dea72d0.png)
If you don't want it to be displayed on the main or subchart, use the "..." operator.
MA60..MA(C, 60); // Calcular el indicador medio con el parámetro de 60
You can use ```DOT``` and ```COLORRED``` to set the line type and color of the line, etc., in line with the habits of users familiar with the MyLanguage.
- ## Common problems
> Introduce the **problems** commonly encountered in the process of writing indicators, usually the points that need to be paid attention to when writing (continuously added).
- Remark the semicolon ```;``` at the end.
- Remark that system keywords cannot be declared as variables.
- Remark that the string uses **single quotes**, for example: the string ```'Open position'```.
- ### Remark
Annotation
- ```// The Remark content ``` (input method can be typed in both Chinese and English) means that the code is not compiled during the execution process, that is, the content after ```//``` is not executed. Usually we use it to mark the meaning of the code, when it is convenient for code review, it can be quickly understood and recalled.
- ```{ Remark content }```Block Remark.
```
A:=MA(C,10);
{The previous line of code is to calculate the moving average.}
```
- ```(* Remark content *)```Block Remark.
```
A:=MA(C,10);
(*The previous line of code is to calculate the moving average.*)
```
- ### Input
When writing code, because the input method is often switched between Chinese and English, resulting in symbol errors. The common errors are as follows: colon ```:```, terminator ```;```, comma ```, ```, brackets ```()```, etc. These characters in different states of Chinese and English need attention.
> If you use Sogou, Baidu, or Bing input methods, you can quickly switch between Chinese and English by pressing the ```shift``` key once.
- ### Error-prone logic
1. At least, not less than, not less than: the corresponding relational operator ```>=```.
2. Up to, at most, no more than: the corresponding relational operator ```<=```.
- ### Strategy launch synchronization
In the futures strategy, if there is a manually opened position before the strategy robot starts, when the robot starts, it will detect the position information and synchronize it to the actual position status.
In the strategy, you can use the ```SP```, ```BP```, ```CLOSEOUT``` commands to close the position.

2.Return the current X value when N is 0;
3.Return a null value when N is null.
4.N can be a variable.
Example 1:
REF(CLOSE,5);Indicate the closing price of the 5th period before the current period is referenced
Example 2:
AA:=IFELSE(BARSBK>=1,REF(C,BARSBK),C);//Take the closing price of the K-line of the latest position opening signal
// 1)When the BK signal is sent, the bar BARSBK returns null, then the current K-line REF(C, BARSBK) that sends out the BK signal returns null;
// 2)When the BK signal is sent out, the K-line BARSBK returns null, and if BARSBK>=1 is not satisfied, it is the closing price of the K-line.
// 3)The K-line BARSBK after the BK signal is sent, returns the number of periods from the current K-line between the K-line for purchasing and opening a position, REF(C,BARSBK)
Return the closing price of the opening K-line.
// 4)Example: three K-lines: 1, 2, and 3, 1 K-line is the current K-line of the position opening signal, then returns the closing price of the current K-line, 2, 3
The K-line returns the closing price of the 1 K-line.

BARPOS, Returns the number of periods from the first K-line to the current one.
Remarks:
1.BARPOS returns the number of locally available K-line, counting from the data that exists on the local machine.
2.The return value of the first K-line existing in this machine is 1.
Example 1:LLV(L,BARPOS); // Find the minimum value of locally available data.

Es el momento de tomar la línea K.
TIME, the time of taking the K-line.
Remarks:
1.The function returns in real time in the intraday, and returns the starting time of the K-line after the K-line is completed.
2.This function returns the exchange data reception time, which is the exchange time.
3.The TIME function returns a six-digit form when used on a second period, namely: HHMMSS, and displays a four-digit form on other periods, namely: HHMM.
4.The TIME function can only be loaded in periods less than the daily period, and the return value of the function is always 1500 in the daily period and periods above the daily period.
5. It requires attention when use the TIME function to close a position at the end of the day
(1).It is recommended to set the time for closing positions at the end of the market to the time that can actually be obtained from the return value of the K-line (for example: the return time of the last K-line in the 5-minute period of the thread index is 1455, and the closing time at the end of the market is set to TIME>=1458, CLOSEOUT; the signal of closing the position at the end of the market cannot appear in the effect test)
(2).If the TIME function is used as the condition for closing the position at the end of the day, it is recommended that the opening conditions should also have a corresponding time limit (for example, if the condition for closing the position at the end of the day is set to TIME>=1458, CLOSEOUT; then the condition TIME needs to be added to the corresponding opening conditions. <1458; avoid re-opening after closing)
Example 1:
C>O&&TIME<1450,BK;
C<O&&TIME<1450,SK;
TIME>=1450,SP;
TIME>=1450,BP;
AUTOFILTER;
// Close the position after 14:50.

Remark:
The value range of DAY is 1-31.
Example 1:
DAY=3&&TIME=0915,BK; // 3 days from the same day, at 9:15, buy it
Example 2:
N:=BARSLAST(DATE<>REF(DATE,1))+1;
CC:=IFELSE(DAY=1,VALUEWHEN(N=1,O),0); // When the date is 1, the opening price is taken, otherwise the value is 0

Devuelva el estado de la posición para el período actual.
BARSTATUS returns the position status for the current period.
Remark:
The function returns 1 to indicate that the current period is the first period, returns 2 to indicate that it is the last period, and returns 0 to indicate that the current period is in the middle.
Example:
A:=IFELSE(BARSTATUS=1,H,0); // If the current K-line is the first period, variable A returns the highest value of the K-line, otherwise it takes 0
Between.
BETWEEN(X,Y,Z) indicates whether X is between Y and Z, returns 1 (Yes) if established, otherwise returns 0 (No).
Remark:
1.The function returns 1(Yse) if X=Y, X=Z, or X=Y and Y=Z.
Example 1:
BETWEEN(CLOSE,MA5,MA10); // It indicates that the closing price is between the 5-day moving average and the 10-day moving average
BARSLASTCOUNT(COND) cuenta el número de períodos consecutivos que satisfacen la condición, contando hacia adelante desde el período actual.
Remark:
1. The return value is the number of consecutive non zero periods calculated from the current period
2. the first time the condition is established when the return value of the current K-line BARSLASTCOUNT(COND) is 1
Example:
BARSLASTCOUNT(CLOSE>OPEN);
//Calculate the number of consecutive positive periods within the current K-line
Función cruzada.
CROSS(A,B) means that A crosses B from bottom to top, and returns 1 (Yes) if established, otherwise returns 0 (No)
Remark:
1.To meet the conditions for crossing, the previous k-line must satisfy A<=B, and when the current K-line satisfies A>B, it is considered to be crossing.
Example 1:
CROSS(CLOSE,MA(CLOSE,5)); // Indicates that the closing line crosses the 5-period moving average from below
Descenso
CROSSDOWN(A,B): indicates that when A passes through B from top to bottom, it returns 1 (Yes) if it is established, otherwise it returns 0 (No)
Remark:
1.CROSSDOWN(A,B) is equivalent to CROSS(B,A), and CROSSDOWN(A,B) is easier to understand
Example 1:
MA5:=MA(C,5);
MA10:=MA(C,10);
CROSSDOWN(MA5,MA10),SK; // MA5 crosses down MA10 to sell and open a position
// CROSSDOWN(MA5,MA10),SK; Same meaning as CROSSDOWN(MA5,MA10)=1,SK;
Crossup.
CROSSUP(A,B) means that when A crosses B from the bottom up, it returns 1 (Yes) if it is established, otherwise it returns 0 (No)
Remark:
1.CROSSUP(A,B) is equivalent to CROSS(A,B), and CROSSUP(A,B) is easier to understand.
Example 1:
MA5:=MA(C,5);
MA10:=MA(C,10);
CROSSUP(MA5,MA10),BK; // MA5 crosses MA10, buy open positions
// CROSSUP(MA5,MA10),BK;与CROSSUP(MA5,MA10)=1,BK; express the same meaning
Determinar si se satisface continuamente.
EVERY(COND,N), Determine whether the COND condition is always satisfied within N periods. The return value of the function is 1 if it is satisfied, and 0 if it is not satisfied.
Remarks:
1.N contains the current K-line.
2.If N is a valid value, but there are not so many K-lines in front, or N is a null value, it means that the condition is not satisfied, and the function returns a value of 0.
3.N can be a variable.
Example 1:
EVERY(CLOSE>OPEN,5); // Indicates that it has been a positive line for 5 periods
Example 2:
MA5:=MA(C,5); // Define a 5-period moving average
MA10:=MA(C,10); // Define a 10-period moving average
EVERY(MA5>MA10,4),BK; // If MA5 is greater than MA10 within 4 periods, then buy the open position
// EVERY(MA5>MA10,4),BK; has the same meaning as EVERY(MA5>MA10,4)=1,BK;
Determine si hay satisfacción.
EXIST(COND, N) judges whether there is a condition that satisfies COND within N periods.
Remarks:
1.N contains the current K-line.
2.N can be a variable.
3.If N is a valid value, but there are not so many K-lines in front, it is calculated according to the actual number of periods.
Example 1:
EXIST(CLOSE>REF(HIGH,1),10); // Indicates whether there is a closing price greater than the highest price of the previous period in 10 periods, returns 1 if it exists, and returns 0 if it does not exist
Example 2:
N:=BARSLAST(DATE<>REF(DATE,1))+1;
EXIST(C>MA(C,5),N); // Indicates whether there is a K-line that satisfies the closing price greater than the 5-period moving average on the day, returns 1 if it exists, returns 0 if it does not exist
Función de condición.
IF(COND,A,B)Returns A if the COND condition is true, otherwise returns B.
Remarks:
1.COND is a judgment condition; A and B can be conditions or values.
2.This function supports the variable circular reference to the previous period's own variable, that is, supports the following writing Y: IF(CON,X,REF(Y,1)).
Example 1:
IF(ISUP,H,L); // The K-line is the positive line, the highest price is taken, otherwise the lowest price is taken
Example 2:
A:=IF(MA5>MA10,CROSS(DIFF,DEA),IF(CROSS(D,K),2,0)); // When MA5>MA10, check whether it satisfies the DIFF and pass through DEA, otherwise (MA5 is not greater than MA10), when K and D are dead fork, let A be assigned a value of 2, if none of the above conditions are met, A is assigned a value of 0
A=1,BPK; // When MA5>MA10, the condition for opening a long position is to cross DEA above the DIFF
A=2,SPK; // When MA5 is not greater than MA10, use K and D dead forks as the conditions for opening short positions
Función de condición.
Las observaciones: 1.COND es una condición de juicio; A y B pueden ser condiciones o valores. 2.Esta función admite la referencia circular de la variable a la propia variable del período anterior, es decir, admite la siguiente escritura Y: IFELSE(CON,X,REF(Y,1)); Ejemplo 1: IFELSE ((ISUP,H,L); // La línea K es la línea positiva, se toma el precio más alto, de lo contrario se toma el precio más bajo Ejemplo 2: A:=IFELSE(MA5>MA10,CROSS(DIFF,DEA),IFELSE(CROSS(D,K,2,0)); // Cuando MA5>MA10, compruebe si satisface el DIFF y pasa a través de DEA, de lo contrario (MA5 no es mayor que MA10), cuando K y D son bifurcación muerta, asignar a A un valor de 2, si no se cumple ninguna de las condiciones anteriores, A se asigna un valor de 0 A=1,BPK; // Cuando MA5>MA10, la condición para abrir una posición larga es cruzar DEA por encima del DIFF A=2,SPK; // Cuando MA5 no es mayor que MA10, utilizar K y D tenedores muertos como el conditio
