Fungsi Terbina Dalam

_G(K, V)

_G(K, V), dengan fungsi kamus global yang boleh disimpan, menyokong kedua-dua backtest dan bot. Struktur data adalahKVsetiap bot mempunyai pangkalan data yang berasingan. ia akan sentiasa wujud selepas memulakan semula atau apabila docker keluar.Kmestilah rentetan, yang tidak sensitif huruf besar.Vboleh menjadi apa-apaJSONApabila fungsi_G()dipanggil dan tiada parameter yang dihantar dalam operasi bot, fungsi_G()mengembalikanIDdaripada bot semasa.

function main(){
    // Set a global variable num with a value of 1
    _G("num", 1)     
    // Change a global variable num with the value "ok"
    _G("num", "ok")    
    // Delete global variable num
    _G("num", null)
    // Return the value of the global variable num
    Log(_G("num"))
    // Delete all global variables
    _G(null)
    // Return bot 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);
    // does not support auto robotId = _G();
}

Nota: Apabila menggunakan_Gfungsi untuk menyimpan data, ia harus digunakan dengan munasabah mengikut memori dan ruang cakera keras peranti perkakasan, dan tidak boleh disalahgunakan.Penumpukan memori problem.

_D ((Timestamp, Fmt)

_D(Timestamp, Fmt), mengembalikan rentetan masa yang sepadan dengan stempel masa yang ditentukan. Nilai parameter:Timestampadalah jenis numerik, dalam milidetik.Fmtadalah jenis rentetan;Fmtlalai kepada:yyyy-MM-dd hh:mm:ss; nilai pulangan: jenis rentetan. Ia mengembalikan rentetan stempel masa yang ditentukan, dan mengembalikan masa semasa tanpa lulus sebarang parameter; contohnya:_D()atau_D(1478570053241), di mana format lalai adalahyyyy-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);
}

Nota: Apabila digunakan_D()dalamPythonstrategi, kita perlu memberi perhatian bahawa parameter yang dihantar adalah timestamps dalam kedua (timestamps tahap milidetik dalamJavaScriptdanC ++strategi, dan 1 saat = 1000 milidetik). Dalam bot, apabila menggunakan fungsi_D()untuk menganalisis rentetan masa dengan cap masa yang boleh dibaca, anda perlu memberi perhatian kepada zon masa dalam sistem operasi program docker. fungsi_D()Menganalisis stempel masa sebagai rentetan masa yang boleh dibaca berdasarkan masa sistem docker.

Sebagai contoh, menganalisis stempel masa1574993606000dengan kod:

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

def main():
    # Beijing time server runs: 2019-11-29 10:13:26, and the docker on another server in another region runs this code will get the results: 2019-11-29 02:13:26
    Log(_D(1574993606))

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

_N(Nombor, ketepatan)

_N(Num, Precision), nombor koma terapung berformat. Nilai parameter:Numadalah jenis nombor;Precisionadalah jenis bilangan bulat. Nilai balik: jenis nombor.

Contohnya:_N(3.1415, 2)akan memadamkan nilai selepas dua tempat perpuluhan3.1415dan kembali3.14.

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);
}

Jika anda perlu menukar N digit di sebelah kiri titik perpuluhan kepada 0, anda boleh menulis:

function main(){
    var i = 1300
    Log(i)
    var ii = _N(i, -3)
    // Checking the log shows that it is 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…)adalah fungsi cubaan semula, digunakan untuk toleransi ralat antara muka mengenai mendapatkan maklumat pasaran dan memperoleh pesanan yang belum selesai, dll.

Antara muka akan memanggil fungsi yang ditentukan secara berterusan sehingga ia kembali dengan berjaya (parameterfunctionmengembalikan nilai null apabila memanggil fungsi rujukan ataufalseakan cuba panggilan semula). Sebagai contoh,_ C(exchange. GetTicker), selang cuba semula lalai adalah 3 saat, yang boleh memanggil fungsi_CDelay (...)untuk menetapkan selang percubaan semula, seperti_CDelay (1000)bermaksud fungsi perubahan_CPercubaan semula untuk 1 saat.

Untuk fungsi berikut:

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

Mereka semua boleh dipanggil untuk melakukan toleransi ralat oleh fungsi_C(...). Fungsi_C(function, args...)tidak terhad kepada toleransi ralat fungsi yang disenaraikan di atas.functionadalah dipetik tidak dipanggil, dan memberi perhatian bahawa ia adalah_C(exchange.GetTicker), tidak_C(exchange.GetTicker()).

function main(){
    var ticker = _C(exchange.GetTicker)
    // Adjust _C() function's retry interval to 2 seconds
    _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);
}

Untuk fungsi dengan parameter, apabila menggunakan_C(...)untuk melakukan toleransi ralat:

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);
}

Ia juga boleh digunakan untuk penanganan toleransi ralat fungsi tersuai:

var test = function(a, b){
    var time = new Date().getTime() / 1000
    if(time % b == 3){
        Log("Meet the criteria! ", "#FF0000")
        return true
    }
    Log("Retry!", "#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("Meet the criteria!", "#FF0000")
        return True
    Log("Retry!", "#FF0000")
    return False

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

// C++ does not support this method for fault tolerance of custom functions.

_Silang ((Arr1, Arr2)

_Cross(Arr1, Arr2)mengembalikan bilangan tempoh persimpangan arrayarr1danarr2. nombor positif adalah tempoh kenaikan, dan nombor negatif adalah tempoh penurunan, dan 0 bermaksud sama dengan harga semasa. nilai parameter: pelbagai jenis nombor.

Anda boleh mensimulasikan satu set data untuk menguji fungsi_Cross(Arr1, Arr2):

// Fast line indicator
var arr1 = [1,2,3,4,5,6,8,8,9]
// Slow line indicator
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};
    Log("_Cross(arr1, arr2) : ", _Cross(arr1, arr2));
    Log("_Cross(arr2, arr1) : ", _Cross(arr2, arr1));
}

JSONParse ((strJson)

JSONParse(strJson), fungsi ini digunakan untuk menganalisis rentetan JSON. rentetan JSON yang mengandungi nombor besar boleh dianalisis dengan betul, dan nombor besar akan dianalisis ke dalam jenis rentetan. Sistem backtesting tidak menyokong fungsi ini.

function main() {
    let s1 = '{"num": 8754613216564987646512354656874651651358}'
    Log("JSON.parse:", JSON.parse(s1))    // JSON.parse: {"num":8.754613216564988e+39}
    Log("JSONParse:", JSONParse(s1))      // JSONParse:  {"num":"8754613216564987646512354656874651651358"}
    
    let s2 = '{"num": 123}'
    Log("JSON.parse:", JSON.parse(s2))    // JSON.parse: {"num":123}
    Log("JSONParse:", JSONParse(s2))      // JSONParse:  {"num":123}
}

import json

Warna tersuai

Setiap rentetan mesej boleh berakhir dengan nilai RGB seperti:#ff0000, yang mewakili warna latar depan yang akan dipaparkan. Jika ia dalam format seperti#ff0000112233, enam bahagian belakang terakhir mewakili warna latar belakang.

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

def main():
    Log("Red", "#FF0000")

void main() {
    Log("Red", "#FF0000");
}

Maklumat Log

Apabila bot berjalan, maklumat log dicatat dalam pangkalan data bot, yang menggunakansqlite3fail pangkalan data terletak di dalam peranti dengan program docker, dan lokasi yang tepat fail adalah dalam kamus program docker (robotcontoh: fail pangkalan data bot dengan ID130350berada dalam direktori../logs/storage/130350 (..adalah kamus di mana pelabuhan darirobotterletak), dan nama fail pangkalan data adalah130350.db3.

Log dalam sistem backtest boleh dimuat turun dengan mengklik [Muat turun log] butang di sudut kanan bawah halaman backtest selepas backtest selesai. Apabila anda perlu memindahkan bot ke docker pada pelayan lain, anda boleh memindahkan fail pangkalan data bot (fail pangkalan data dengan sambungan db3) ke pelayan sasaran pemindahan, dan menetapkan nama fail ke ID bot yang sepadan di platform. Dengan cara ini, semua maklumat log bot sebelumnya tidak akan hilang kerana migrasi ke peranti baru.

Log ((...)

Log(message)bermaksud menyimpan mesej ke dalam senarai log. Nilai parameter:messageboleh menjadi apa-apa jenis. Jika anda menambah watak@selepas rentetan, mesej akan memasuki antrian push dan akan didorong ke akaun WeChat semasa platform FMZ Quant Trading, dan Email, Telegram dan WebHook di Push settings akan didorong (buka halamanDasbor, AkaundanTetapan tekanoleh perintah untuk menetapkan ikatan).

Nota:

• Push tidak disokong dalam Debug Tool.
• Push tidak disokong dalam Backtest System.

function main() {
    Log("Hello FMZ Quant!@")
    Sleep(1000 * 5)
    // Add the string to #ff0000, print the log in red, and push the message
    Log("Hello, #ff0000@")
}

def main():
    Log("Hello FMZ Quant!@")
    Sleep(1000 * 5)
    Log("Hello, #ff0000@")

void main() {
    Log("Hello FMZ Quant!@");
    Sleep(1000 * 5);
    Log("Hello, #ff0000@");
}

WebHookTekan:

Gunakan program perkhidmatan DEMO yang ditulis dalamGolang:

package main
import (
    "fmt"
    "net/http"
)

func Handle (w http.ResponseWriter, r *http.Request) {
    defer func() {
        fmt.Println("req:", *r)
    }()
}

func main () {
    fmt.Println("listen http://localhost:9090")
    http.HandleFunc("/data", Handle)
    http.ListenAndServe(":9090", nil)
}

SetWebHook: http://XXX.XX.XXX.XX:9090/data?data=Hello_FMZ

Selepas menjalankan program perkhidmatan, melaksanakan strategi dan tekan maklumat:

function main() {
    Log("msg", "@")
}

def main():
    Log("msg", "@")

void main() {
    Log("msg", "@");
}

Menerima maklumat dorong, dan program perkhidmatan mencetak maklumat:

listen http://localhost:9090
req: {GET /data?data=Hello_FMZ HTTP/1.1 1 1 map[User-Agent:[Mozilla/5.0 (Macintosh; Intel Mac OS X 10_9_3) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/xx.x.xxxx.xxx Safari/537.36] Accept-Encoding:[gzip]] {} <nil> 0 [] false 1XX.XX.X.XX:9090 map[] map[] <nil> map[] XXX.XX.XXX.XX:4xxx2 /data?data=Hello_FMZ <nil> <nil> <nil> 0xc420056300}

Cetakbase64imej dikodkanFungsiLogmenyokong mencetak imej yang dikodkan dalambase64, bermula mereka dengan`, dan berakhir dengan`Contohnya:

function main() {
    Log("`data:image/png;base64,AAAA`")
}

def main():

void main() {
    Log("`data:image/png;base64,AAAA`");
}

Logmenyokong mencetakmatplotlib.pyplotobjek-objekPythonsecara langsung, iaitu, selagi objek mengandungisavefigkaedah, anda boleh menggunakanLoguntuk mencetak secara langsung, contohnya:

import matplotlib.pyplot as plt 
def main(): 
    plt.plot([3,6,2,4,7,1]) 
    Log(plt)

Pertukaran bahasa automatik log cetakFungsiLogmenyokong pertukaran bahasa; apabila fungsi output teks, ia akan beralih ke bahasa yang sepadan secara automatik mengikut tetapan bahasa pada halaman platform. Sebagai contoh:

function main() {
    Log("[trans]Chinese|abc[/trans]")
}

def main():
    Log("[trans]Chinese|abc[/trans]")

void main() {
    Log("[trans]Chinese|abc[/trans]");
}

LogProfit ((Profit)

LogProfit(Profit)merakam nilai keuntungan, mencetak nilai keuntungan, dan melukis lengkung keuntungan mengikut nilai keuntungan.Keuntunganadalah jenis nombor.

Jika fungsi berakhir dengan watak&, ia hanya boleh merealisasikan melukis carta keuntungan, dan tidak mencetak log keuntungan, seperti:LogProfit(10, '&').

LogProfitReset (()

LogProfitReset()menghapuskan semua log keuntungan; anda boleh mengambil parameter nilai bilangan bulat untuk menentukan bilangan item yang disediakan.

function main() {
    // Print 30 points on the income chart, then reset, and only retain the last 10 points 
    for(var i = 0; i < 30; i++) {
        LogProfit(i)
        Sleep(500)
    }
    LogProfitReset(10)
}

def main():
    for i in range(30):
        LogProfit(i)
        Sleep(500)
    LogProfitReset(10)

void main() {
    for(int i = 0; i < 30; i++) {
        LogProfit(i);
        Sleep(500);
    }
    LogProfitReset(10);
}

LogStatus ((Msg)

LogStatus(Msg), maklumat tidak disimpan dalam senarai log, hanya maklumat status semasa bot dikemas kini; ia dipaparkan di atas log dan boleh dipanggil beberapa kali untuk mengemas kini status. Nilai parameter:Msgboleh menjadi apa-apa jenis.

function main() {
    LogStatus('This is a normal status prompt')
    LogStatus('This is a status prompt in red font # ff0000')
    LogStatus('This is a multi-line status message \n I am the second line')
}

def main():
    LogStatus('This is a normal status prompt')
    LogStatus('This is a status prompt in red font # ff0000')

    LogStatus('`' + JSON.stringify(table) + '`')                    
    // Table information can also appear in multiple lines
    LogStatus('First line message\n`' + JSON.stringify(table) + '`\nThird line message')
    // That supports multiple tables displayed at the same time, and that will be displayed in a group with TAB
    LogStatus('`' + JSON.stringify([table, table]) + '`')
    
    // You can also construct a button in the table, and the strategy uses "GetCommand" to receive the content of the cmd attribute

Apabila membina butang bar status untuk interaksi, data input juga disokong, dan arahan interaktif akhirnya ditangkap olehGetCommand()fungsi. Untuk menambahinputitem kepada struktur data kawalan butang dalam bar status, contohnya, menambah"input": {"name": "Number of opening orders", "type": "number", "defValue": 1}kepada{"type": "button", "cmd": "open", "name": "open position"}, anda boleh membuat butang muncul kotak dialog dengan kawalan kotak input apabila diklik (nilai lalai dalam kotak input adalah 1, yang ditetapkan oleh data defValue), dan anda boleh memasukkan data untuk dihantar dengan perintah butang. Sebagai contoh, apabila menjalankan kod ujian berikut, selepas mengklik butang Open position, kotak dialog dengan kotak input muncul. Selepas memasukkan111dalam kotak input dan mengklik OK,GetCommandfungsi akan menangkap mesej:open:111.
