MT5 開倉單返回“無”

Question

我是新手，正在嘗試為 MT5 構建 python 機器人。 我試圖通過 python 在 MT5 中發送交易，但它總是返回“無”。

我已經輸入了所有必需的信息，可能是因為小數錯誤嗎？

import os
from datetime import datetime
import MetaTrader5 as mt5
import requests
import datetime as dt  # for dealing with times
import numpy as np
import json
import pandas as pd
import pytz

ea_magic_number = 9986989 # if you want to give every bot a unique identifier

def open_trade(action, symbol, lot, sl_points, tp_points, deviation):
    '''https://www.mql5.com/en/docs/integration/python_metatrader5/mt5ordersend_py
    '''
    # prepare the buy request structure
    symbol_info = mt5.symbol_info(symbol)

    if action == 'buy':
        trade_type = mt5.ORDER_TYPE_BUY
        price = mt5.symbol_info_tick(symbol).ask
    elif action =='sell':
        trade_type = mt5.ORDER_TYPE_SELL
        price = mt5.symbol_info_tick(symbol).bid
    point = mt5.symbol_info(symbol).point


    action_request = {
        "action": mt5.TRADE_ACTION_DEAL,
        "symbol": symbol,
        "volume": lot,
        "type": trade_type,
        "price": price,
        "sl": round(price - sl_points * point,5),
        "tp": price + tp_points * point,
        "deviation": deviation,
        "magic": ea_magic_number,
        "comment": "sent by python",
        "type_time": mt5.ORDER_TIME_GTC, # good till cancelled
        "type_filling": mt5.ORDER_FILLING_RETURN
    }
    # send a trading request
    result = mt5.order_send(action_request)
    return result, action_request

def close_trade(action, action_request, result, deviation):
    '''https://www.mql5.com/en/docs/integration/python_metatrader5/mt5ordersend_py
    '''
    # create a close request
    symbol = action_request['symbol']

    if action == 'buy':
        trade_type = mt5.ORDER_TYPE_BUY
        price = mt5.symbol_info_tick(symbol).ask
    elif action =='sell':
        trade_type = mt5.ORDER_TYPE_SELL
        price = mt5.symbol_info_tick(symbol).bid
    position_id=result.order
    lot = action_request['volume']

    action_request={
        "action": mt5.TRADE_ACTION_DEAL,
        "symbol": symbol,
        "volume": lot,
        "type": mt5.ORDER_TYPE_SELL,
        "position": position_id,
        "price": price,
        "deviation": deviation,
        "magic": ea_magic_number,
        "comment": "python script close",
        "type_time": mt5.ORDER_TIME_GTC, # good till cancelled
        "type_filling": mt5.ORDER_FILLING_RETURN,
    }
    # send a close request
    result=mt5.order_send(action_request)

currency_pair = "GBPUSD"


# establish connection to MetaTrader 5 terminal
if not mt5.initialize(login=31706337, server="MetaQuotes-Demo",password="mzhjm8hi"):
    print("initialize() failed, error code =", mt5.last_error())
    quit()


trade = open_trade('buy', currency_pair, 10, 500, 2000, 10)
print(trade)

結果：C:\Users\andyq\PycharmProjects\BinanceTrading\venv\Scripts\python.exe "C:/Users/andyq/PycharmProjects/BinanceTrading/data prepare.py"

(None, {'action': 1, 'symbol': 'GBPUSD', 'volume': 10, 'type': 0, 'price': 1.26224, 'sl': 1.25724, 'tp': 1.28224, 'deviation': 10, 'magic': 9986989, 'comment': 'sent by python', 'type_time': 0, 'type_filling': 2})

Answer 1

音量應該是 Double 所以：

'volume': 10

應該：

'volume': 10.0

Answer 2

我遇到了同樣的問題，為了解決這個問題，你應該檢查請求字典中的所有數據類型。 交易量、止損、止盈和價格應該是浮動值並記住訂單應該是整數
