Built-in functions

_G(K, V)

_G(K, V)The function implements a saveable global dictionary function, which supports both retrieval and disk; after retrieval, the saved data is cleared. The data structure isKVTables, permanently stored local files, a separate database on each disk, that remain after a restart or administrator logs out.KIt has to be written as a string, without a big or small distinction.VIt can be used for anything.JSONSequential content. Calls during disk operation._G()If the function does not pass any parameters, then the function is not a function._G()The function returns the current disk.ID。

function main(){
    // 设置一个全局变量num，值为1
    _G("num", 1)     
    // 更改一个全局变量num，值为字符串ok
    _G("num", "ok")    
    // 删除全局变量num
    _G("num", null)
    // 返回全局变量num的值
    Log(_G("num"))
    // 删除所有全局变量
    _G(null)
    // 返回实盘ID
    var robotId = _G()
}

def main():
    _G("num", 1)     
    _G("num", "ok")    
    _G("num", None)
    Log(_G("num"))
    _G(None)
    robotId = _G()

void main() {
    _G("num", 1);
    _G("num", "ok");
    _G("num", NULL);
    Log(_G("num"));
    _G(NULL);
    // 不支持 auto robotId = _G();
}

Please note: Use_GWhen storing functional persistent data, the memory and hard disk space of the hardware device should be used reasonably and not abused; otherwise, it may causeMemory leakageThe question is:

_D(Timestamp, Fmt)

_D(Timestamp, Fmt), returns the time string of the specified time frame.TimestampFor the numeric type, the value is milliseconds.FmtFor the string type,FmtThe implication is:yyyy-MM-dd hh:mm:ss, returns the value: String type. Returns the string that corresponds to the specified time frame (milli-second) without passing any parameters._D()Or_D(1478570053241)The default format isyyyy-MM-dd hh:mm:ss。

function main(){
    var time = _D()
    Log(time)
}

def main():
    strTime = _D()
    Log(strTime)

void main() {
    auto strTime = _D();
    Log(strTime);
}

Please note:PythonStrategic use_D()The parameters that need to be taken into consideration are the second-level time stamp.JavaScript、C++In the strategy, a millisecond-scale timestamp is used, where 1 second equals 1000 milliseconds). Use in real time_D()When a function parses a timestamp as a readable time string, it is necessary to pay attention to the time zone and time setting of the operating system where the host program is located._D()The function parses a time stamp as a readable time string that is set based on the time of the host system.

For example, a time frame is1574993606000Use code to parse:

function main() {
    Log(_D(1574993606000))
}

def main():
    # 北京时间的服务器上运行：2019-11-29 10:13:26 ，另一台其它地区的服务器上的托管者运行此代码结果则为：2019-11-29 02:13:26
    Log(_D(1574993606))

void main() {
    Log(_D(1574993606000));
}

_N(Num, Precision)

_N(Num, Precision), format a floating point number.NumFor the numerical type,PrecisionFor the integer type. Return value: numeric type.

For example,_N(3.1415, 2)Will be deleted3.1415The function returns the value after the decimal point.3.14。

function main(){
    var i = 3.1415
    Log(i)
    var ii = _N(i, 2)
    Log(ii)
}

def main():
    i = 3.1415
    Log(i)
    ii = _N(i, 2)
    Log(ii)

void main() {
    auto i = 3.1415;
    Log(i);
    auto ii = _N(i, 2);
    Log(ii);
}

If you want to change all the n digits to the left of the decimal point to 0, you can write it like this:

function main(){
    var i = 1300
    Log(i)
    var ii = _N(i, -3)
    // 查看日志得知为1000
    Log(ii)
}

def main():
    i = 1300
    Log(i)
    ii = _N(i, -3)
    Log(ii)

void main() {
    auto i = 1300;
    Log(i);
    auto ii = _N(i, -3);
    Log(ii);
}

_C(…)

_C(function, args...)This function is a re-test function, which is used to retrieve transactions, retrieve unfinished orders, etc.

The interface will continue to call the specified function until it successfully returns the ((parameter)functionReturns a null value when a function is called orfalseI'm going to try calling you again.)_C(exchange.GetTicker)By default, you can call the default retry interval of 3 seconds._CDelay(...)Functions to set retest intervals, such as_CDelay(1000), refers to change_CRe-test the function with an interval of 1 second.

For the following functions:

• exchange.GetTicker()
• exchange.GetDepth()
• exchange.GetTrades()
• exchange.GetRecords()
• exchange.GetAccount()
• exchange.GetOrders()
• exchange.GetOrder()
• exchange.GetPosition()

It's all good._C(...)Function to call error tolerance._C(function, args...)Functions are not limited to the error tolerance of the functions listed above, parametersfunctionIt's a function reference, not a function call._C(exchange.GetTicker)It's not_C(exchange.GetTicker())。

function main(){
    var ticker = _C(exchange.GetTicker)
    // 调整_C()函数重试时间间隔为2秒
    _CDelay(2000)
    var depth = _C(exchange.GetDepth)
    Log(ticker)
    Log(depth)
}

def main():
    ticker = _C(exchange.GetTicker)
    _CDelay(2000)
    depth = _C(exchange.GetDepth)
    Log(ticker)
    Log(depth)

void main() {
    auto ticker = _C(exchange.GetTicker);
    _CDelay(2000);
    auto depth = _C(exchange.GetDepth);
    Log(ticker);
    Log(depth);
}

Use for functions with parameters_C(...)When to make mistakes:

function main(){
    var records = _C(exchange.GetRecords, PERIOD_D1)
    Log(records)
}

def main():
    records = _C(exchange.GetRecords, PERIOD_D1)
    Log(records)

void main() {
    auto records = _C(exchange.GetRecords, PERIOD_D1);
    Log(records);
}

It can also be used for error tolerance for custom functions:

var test = function(a, b){
    var time = new Date().getTime() / 1000
    if(time % b == 3){
        Log("符合条件！", "#FF0000")
        return true
    }
    Log("重试！", "#FF0000")
    return false
}

function main(){
    var ret = _C(test, 1, 5)
    Log(ret)
}

import time
def test(a, b):
    ts = time.time()
    if ts % b == 3:
        Log("符合条件！", "#FF0000")
        return True
    Log("重试！", "#FF0000")
    return False

def main():
    ret = _C(test, 1, 5)
    Log(ret)

// C++ 不支持这种方式对于自定义函数容错

_Cross(Arr1, Arr2)

_Cross(Arr1, Arr2)Returns the array.arr1andarr2The number of cross cycles of the array. A positive number is the up-and-down cycle, a negative number is the down-and-down cycle, and 0 is the same as the current price.

It can simulate a set of data tests._Cross(Arr1, Arr2)The function:

// 快线指标
var arr1 = [1,2,3,4,5,6,8,8,9]
// 慢线指标
var arr2 = [2,3,4,5,6,7,7,7,7]
function main(){
    Log("_Cross(arr1, arr2) : ", _Cross(arr1, arr2))
    Log("_Cross(arr2, arr1) : ", _Cross(arr2, arr1))
}

arr1 = [1,2,3,4,5,6,8,8,9]     
arr2 = [2,3,4,5,6,7,7,7,7]
def main():
    Log("_Cross(arr1, arr2) : ", _Cross(arr1, arr2))
    Log("_Cross(arr2, arr1) : ", _Cross(arr2, arr1))

void main() {
    vector<double> arr1 = {1,2,3,4,5,6,8,8,9};
    vector<double> arr2 = {2,3,4,5,6,7,7,7,7};

Customized colors

Each message string can be used.#ff0000This RGB value at the end represents the foreground that needs to be displayed.#ff0000112233In this format, the last six characters represent the background colour.

function main() {
    Log("红色", "#FF0000")
}

def main():
    Log("红色", "#FF0000")

void main() {

Log information

Log information is stored in the database of the disk while the disk is running, using the database of the disksqlite3Databases, on-disc database files on the device where the host program is located, database files on the host program (((robotIn the executable directory. For example:130350The database files on the hard disk are../logs/storage/130350In this directory..I mean,robotThe directory where the administrator program is located), the database file is called130350.db3I'm not going to lie. The logs in the retrieval system can be retrieved after the retrieval is complete by clicking the retrieval button in the bottom right corner of the page.Download the log] button to download. When a host on another server needs to migrate a disk, it can move the database file on the disk (extension named db3) to the migration destination server, setting the file name to the corresponding disk ID on the platform. This way, all log information on the previous disk is not lost when moving to the new device.

Log(…)

It also supports input data when the Build State Button interacts, and interaction instructions are ultimately executed by the Build State Button.GetCommand()Function capture. Increase in data structure of button controls in the status barinputFor example, give{"type": "button", "cmd": "open", "name": "开仓"}Increased"input": {"name": "开仓数量", "type": "number", "defValue": 1}When the button is clicked, a pop-up window with an input box control (data set to defValue by default in the input box) can be entered and sent along with the button command. For example, when the following test code is run, a pop-up window with an input box pops up after clicking the "Open" button and is entered in the input box.111After that, click "Confirm".GetCommandThe function captures the message:open:111。

Running effects:

Please note: When the policy is running on the hard disk, the status bar will go into sleep mode and stop updating if the history is reviewed on the hard disk page. Only the status bar data will refresh when the log is on the first page. Supports output in the status barbase64Encoded images, also supported for output in the form shown in the status barbase64Post-encoded images. The example code is no longer displayed because the string data of post-encoded images is generally very long.

• cfgA.extension.layoutAttributes

  If this property is set to "single", the graph will not be overlaid (not displayed as a split-page tag) and will be displayed separately (flat display).

• cfgA.extension.heightAttributes

  This property is used to set the height of the chart, which can be set to a numerical type, or to "300px".

• cfgA.extension.colAttributes

  This property is used to set the width of the chart, which is divided into 12 units of page width, and set to 8, which means that the chart is 8 units wide.

  The following is a complete example of a strategy:

  • The JavaScript version
  • Python version
  • C++ version

  The graph configuration object in the example above shows the effect:

  

• Data on the chart configuration object can be updated by modifying the chart configuration directly and then updating the chart:

  For example, in this example,JavaScriptParts of the code paragraph of the exampleThe complete paradigm）：

  cfgC.series[0].data[0][1] = Math.random() * 100
  cfgE.series[0].data[0][1] = Math.random() * 100
  // update实际上等于重置了图表的配置
  chart.update([cfgA, cfgB, cfgC, cfgD, cfgE])
  

  AdoptedaddMethods to update data, such as adding an item to a pie chart,JavaScriptParts of the code paragraph of the exampleThe complete paradigm）：

  // 为饼图增加一个数据点，add只能更新通过add方式添加的数据点，内置的数据点无法后期更新
  chart.add(3, {
      name: "ZZ",
      y: Math.random() * 100
  })
  

• Additional useChartExamples of functions

  A simple example of a graphic:

  // 这个chart在JavaScript语言中是对象，在使用Chart函数之前我们需要声明一个配置图表的对象变量chart
  var chart = {                                           
      // 该字段标记图表是否为一般图表，有兴趣的可以改成false运行看看
