(2)After the BP signal is sent, the K-line BARSBP returns to the number of periods from the K-line for buying and closing positions to the current K-line. If the condition of BARSBP>=1 is satisfied, the value is HHV(H, BARSBP+1), that is, the maximum value of the buying and closing positions (including the current K-line when the close signal appears) to the current highest price. 3.AA:=IFELSE(BARSBP>=1,REF(C,BARSBP),C);//Take the closing price of the last K-line to buy and close the position: (1)When the BARSBP of the current K-line that sends the BP signal returns null, then when the K-line does not meet the condition of BARSBP>=1, AA returns to the closing price of the current K-line. (2)The K-line BARSBP after the BP signal is sent returns to the period number of the K-line for buying and closing the position from the current K-line, then AA returns to REF(C, BARSBP), which is the closing price of the closing K-line. (3)For example: three K-lines: 1, 2, and 3, the K-line in 1 is the current K-line of the closing signal, then returns to the closing price of the current K-line, and the K-line AA in 2 and 3 returns to the closing price of the K-line in 1. ```

REFSIG_VOL

Returns to the number of signal lots for the Nth fixed Sig signal counted down from the current K-line (backhand orders take the number of open position lots).

Usage: REFSIG_VOL(Sig,N);, determine the lot size of the Nth fixed Sig signal counting from the current K-line. If there is no sig signal, or if there is no fixed sig signal, the function returns 0.

Remarks: 1.The signals supported by the Sig position are: BK, SK, BP, SP, BPK, SPK,CLOSEOUT,STOP. 2.If the countdown to the Nth fixed Sig signal is on the current K-line, then the function returns to the current signal lot. 4.When N is 0 or null, the function returns 0. 5.The parameter N supports variables.

Examples:
```
// If there are 5 K-lines from the current K-line where the third fixed BK signal is located from the bottom of the current K-line, and the number of signal lots is greater than 2, close all positions
REFSIG_PLACE(BK,3)=5&&REFSIG_VOL(BK,3)>2,SP(BKVOL);
```
REFSIG_PRICE

Returns to the signal price of the Nth fixed Sig signal from the beginning of the current K-line.

Usage: REFSIG_PRICE(Sig,N);, determine the signal price of the Nth fixed Sig signal from the current K-line. If there is no Sig signal, or if there is no fixed Sig signal, the function returns 0.

Remarks: 1.The signals supported by the Sig position are: BK, SK, BP, SP, BPK, SPK,CLOSEOUT,STOP. 2.If there is a fixed Sig signal on the current K-line, then when the function calculates the signal, the signal of the current K-line is included. 3.When N is 0 or null, the function returns null. 4.The parameter N supports variables.

Examples:
```
// If the opening price of the 3rd last fixed BK signal from the current K-line is 3000, and the long position is greater than 0, sell and close the position
REFSIG_PRICE(BK,3)=3000&&BKVOL>0,SP;
```

Usage: COUNTSIG(X,N);Count the number of X signals in N periods. X can be BK, SK, SP, BP, SPK, BPK ,CLOSEOUT,STOP.

Remarks: 1.During the statistical period, (1)Contains the current K-line. (2)If N is 0, then count from the first valid value. (3)When N is a valid value, but the current number of K-line is less than N, count from the first one to the current period. (4)The return value is null when N is null. (5)N can be a variable. 2.When counting signals: (1)The signal execution method is selected as the confirmation signal after the K-line is completed or the review after the K-line is completed (for example: write CHECKSIG(SIG,‘A’,0,‘D’,0,0); in the model), excluding the Signals that are not fixed on the current K-line, that is, return to the number of signals that have been fixed. (2)The signal execution method is selected not to perform signal review (for example: write MULTSIG or MULTSIG_MIN; in the model), including the signal when the current K-line is sent and fixed. 3.The BK signal generated by the BPK command is processed as the BPK signal, and the SK signal generated by the SPK command is the same.

Examples:
```
N:=BARSLAST(DATE<>REF(DATE,1))+1;
BKN:=COUNTSIG(BK,N);
MA5:=MA(C,5);
BKN=0&&C>MA5,BK;                        // There is no BK signal in the day and the latest price is greater than the 5-period moving average, then buy and open a position

Position functions

MYVOL

Take the lot number of orders.

MYVOL take the lot number of orders.

Usage: Take the lot number of orders, it is mostly used for lot calculation when multiple contracts are loaded in the scale in/dump model.

Remark:
Backtesting: Return to the lot size set in the backtesting parameters.

Examples:
// When the order lot size in the loading parameter is set to 3, the order lot size of BK written following is 6
C>O,BK(2*MYVOL);
C<O,SP(BKVOL);

MONEY

Funds available in the account.

MONEY funds available in the account.

Usage: MONEY returns to the available funds in the account for calculation of positions, lot sizes, etc.

Calculation methods:
1.The initial value of MONEY in the account is the starting capital set in the margin parameters.
2.The initial value of MONEY in the historical backtesting is the initial capital set in the backtesting parameters.
3.The MONEY value of the current K-line of the position opening signal: available funds before opening a position - margin for holding positions - handling fee, where margin for holding positions = opening price * margin ratio * trading unit * lot size.
4.Money value of K-line not closed after opening = money value of K-line before opening signal + floating profit and loss profit.
5.The MONEY value of the current K-line of the closing signal: available funds before closing the position + profit and loss of closing the position + margin released by closing the position - handling fee, where the margin released by closing the position = opening price * margin ratio * trading unit * lot size.

Remarks:
1.The signal execution method is 'confirm the order after the K-line is completed' or 'XX order and review after the K-line is completed':
  a.When the signal to open a position is a K-line, the return value of MONEY is the available funds of the previous K-line - margin for opening a position - handling fee.
  b.When the closing signal is a K-line, the return value of MONEY is the available funds of the previous K-line + closing profit and loss + margin released by the position - handling fee.
2.Select the signal execution method as 'send a signal to place an order without reviewing':
  a.When the signal to open a position is a K-line, the return value of MONEY is the available funds of the previous K-line - margin for opening a position - handling fee.
  b.When the closing signal is a K-line, the return value of MONEY is the available funds of the previous K-line + closing profit and loss + margin released by the position - handling fee.
3.The signal execution method is 'When the K-line is completed to confirm the signal to place an order', the closing profit and loss = (the closing price of the K-line of the closing signal - the opening price) * lot size * trading unit - handling fee.
4.When the signal execution method is 'the signal is placed immediately without review', the closing profit and loss = (the order price of the closing signal - the opening price) * lot size * trading unit - handling fee.
5.After the account is initialized, the return value of MONEY is the funds available in the initialization box.

Examples:
K:=MONEY*0.2/(C*MARGIN*UNIT+FEE);               // The number of lots that can be opened with 20% of the account's available funds (this writing method is applicable to contracts that charge a fee based on a fixed number of lots), FEE custom, or calculated

MONEYTOT

Account Equity.

MONEYTOT account Equity.

Usage: MONEYTOT returns to the current account equity, and the model performs position control. It is used for fund management such as order lot size.

Calculation method: MONEYTOT=Account available funds + position margin.

Remarks:
1.The initial value of MONEYTOT in the account is the initial capital set in the margin parameters.
2.The initial value of MONEYTOT in the historical backtesting is the initial capital set in the backtesting parameters.
3.When the account is initialized:
  a.The current signal is the opening signal, and the return value of MONEYTOT is the available funds of the account in the initialization box.
  b.The current signal is the closing signal, then MONEYTOT returns to the available funds of the account + margin in the initialization box.
4.The signal to open a position is the K-line: MONEYTOT = available funds in the account + margin for holding positions.
5.After opening a position and before closing a position: MONEYTOT returns to the available funds in the current account + margin for holding positions.
6.The current k-line of the closing signal: when the position is 0, MONEYTOT = available funds; when the position is not 0, MONEYTOT = available funds + margin occupied by the position.
Remark:
The available funds in the position list are the available funds including floating profit and loss (= current equity - margin occupied by positions).

Examples:
K:=MONEYTOT*0.2/(C*MARGIN*UNIT+FEE); // The number of lots that can be opened with 20% of the account equity(this writing method is applicable to contracts that charge a fixed lot size), FEE customization, or calculation.
