Output information in the status bar of the backtesting system or live trading page.
LogStatus(…msgs)
The parameter msg is the content of the output, and the parameter msg can be passed more than one.
msg
false
string, number, bool, object, array, any type supported by the system such as null.

// It supports multiple tables at the same time, will be displayed in a group with TAB

// You can also construct a button in the form, and use the GetCommand strategy to receive the contents of the cmd attribute

In combination with the GetCommand() function, construct the status bar button interaction function (old button structure):
function main() {
var tbl = {
type: "table",
title: "operation",
cols: ["column1", "column2"],
rows: [
["Open position operation", {"type": "button", "cmd": "open", "name": "open position", "input": {"name": "number of open positions", "type": "number", "defValue": 1}}],
["Close position operation", {"type": "button", "cmd": "coverAll", "name": "close all positions"}]
]
}
LogStatus(_D(), "\n", "`" + JSON.stringify(tbl) + "`")
while (true) {
var cmd = GetCommand()
if (cmd) {
Log("cmd:", cmd)
}
Sleep(1000)
}
}
import json
def main():
tbl = {
"type": "table",
"title": "operation",
"cols": ["column1", "column2"],
"rows": [
["Open position operation", {"type": "button", "cmd": "open", "name": "open position", "input": {"name": "number of open positions", "type": "number", "defValue": 1}}],
["Close position operation", {"type": "button", "cmd": "coverAll", "name": "close all positions"}]
]
}
LogStatus(_D(), "\n", "`" + json.dumps(tbl) + "`")
while True:
cmd = GetCommand()
if cmd:
Log("cmd:", cmd)
Sleep(1000)
void main() {
json tbl = R"({
"type": "table",
"title": "operation",
"cols": ["column1", "column2"],
"rows": [
["Open position operation", {"type": "button", "cmd": "open", "name": "open position", "input": {"name": "number of open positions", "type": "number", "defValue": 1}}],
["Close position operation", {"type": "button", "cmd": "coverAll", "name": "close all positions"}]
]
})"_json;
LogStatus(_D(), "\n", "`" + tbl.dump() + "`");
while(true) {
auto cmd = GetCommand();
if(cmd != "") {
Log("cmd:", cmd);
}
Sleep(1000);
}
}
Input data is also supported when constructing status bar buttons for interaction, and the interaction commands are captured by the GetCommand() function eventually. Add input items (old button structure) to the data structure of the button control in the status bar, for example, adding "input": {"name": "number of open positions", "type": "number", "defValue": 1} to {"type": "button", "cmd": "open", "name": "open position"} will cause a popup with an input box control to appear when the button is clicked (the default value in the input box is 1, which is the data set by defValue). You can enter a data to be sent along with the button command. For example, when the following test code runs, after clicking the "open position’’ button, a popup window with an input box pops up. Enter 111 in the input box and click “OK”. The GetCommand() function will then capture the message: open:111.

var tbl = {

It supports for grouped button controls (old button structure), functionally consistent with status bar buttons that support data entry (set by using the “input” field). Interactive commands are ultimately captured by the GetCommand() function. The difference is that with the "group" field setting, when the button is clicked to trigger the interaction, the dialog that pops up on the page contains a set of group of input controls set up to enter a group of data at once.
A few points to note about the "group" field in the structure of the status bar button control and the group button control:
type property in group supports only the following four types, and the defValue property is the default value.
“selected”: A dropdown box control that uses the | symbol to separate each option in a dropdown box as it is set.
“number”: Numeric input box control.
“string”: String input box control.
“boolean”: Checkbox control, checked for (Boolean) true, unchecked for (Boolean) false."name": "tradePrice@orderType==1" setting, which makes the tradePrice input control available only when the orderType drop-down control is selected as a Pending Order.| symbols to separate the content of the description in Chinese and English.name, description in group and name, description in the button structure do not have the same definitions even though they have the same field names.
The definition of name in group is also different from the definition of name in input.Log("cmd:", cmd) statement in the following example test:
cmd: open:{"orderType":1,"tradePrice":99,"orderAmount":"99","boolean":true}, i.e., what is returned by the GetCommand() function when an interaction occurs: open:{"orderType":1,"tradePrice":99,"orderAmount":"99","boolean":true}.type property of the button control supports only: "button".
Button controls that support input data, i.e. controls with the input property set, the type property in the configuration information of the input field supports multiple control types.
Refer to the following examples:function main() {
// Status bar button control (set input field to implement) testBtn1 button triggered by the page in the drop-down box control using the options field to set options, using the defValue field to set the default options. This is different from the other examples in this chapter, which use defValue to set the options directly.
var testBtn1 = {
type: "button",
name: "testBtn1",
cmd: "cmdTestBtn1",
input: {name: "testBtn1ComboBox", type: "selected", options: ["A", "B"], defValue: 1}
}
/*
Status bar button control (set input field implementation) testBtn2 button triggered by the page in the drop-down box control using the options field to set the options, options field in the options field not only supports the string,
the use of the ```{text: "description", value: "value"}``` structure is also supported. Use the defValue field to set the default option, which can be multiple choice (multiple choice via array structure). Multiple choice requires setting the additional field multiple to a true value.

When the status bar group button control (implemented by setting the group field) and the status bar button control (implemented by setting the input field) are clicked to trigger interaction (old button structure), the drop-down box control in the dialog box that pops up on the page also supports multiple selections. The following example demonstrates how to design a drop-down box control with multiple selection options:

Support to set horizontal and vertical scroll mode of status bar table. Set scroll attribute to "auto", when the number of vertical rows of the status bar table exceeds 20 rows, the content will be scrolled. When the number of horizontal columns exceeds the page display range, the scroll attribute can be used to alleviate the lagging problem of writing a large amount of data in the status bar during live trading. Refer to the following test example:
The information output from the LogStatus() function when the live trading is running is not saved to the live trading database, but it updates the current live trading’s status bar content only.
The LogStatus() function supports printing base64 encoded images, starting with ` and ending with `. For example: LogStatus("`data:image/png;base64,AAAA`").
The LogStatus() function supports passing matplotlib.pyplot objects directly into Python, as long as the object contains the savefig method, it can be passed as a parameter to the LogStatus() function, for example:
import matplotlib.pyplot as plt
def main():
plt.plot([3,6,2,4,7,1])
LogStatus(plt)
When the strategy is running live trading, if you go through the history on the live trading page, the status bar will sleep and stop updating. Only the status bar data will be refreshed when the log is on the first page. It supports outputting base64 encoded images in the status bar, and it also supports outputting base64 encoded images in the table displayed in the status bar. Since the string data of the encoded image is generally very long, the sample code is not shown.
