MT5开仓订单返回"None"

Question

我是新手，正在尝试为MT5构建一个python机器人。我试图通过python发送MT5交易，但它总是返回"；无"；。

我已经输入了所有需要的信息，可能是因为小数错误吗？

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):

# 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)

结果：C： \Users\andyq\PycharmProjects\BinanceTrading\venv\Scripts\python.exe"C：/Users/andyq/PycharmProjects/BinanceTrading/datapreparation.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})

进程已完成，退出代码为0

Answer 1

卷应该是Double所以：

'volume': 10

应该是：

'volume': 10.0

Answer 2

我遇到了同样的问题，为了解决这个问题，您应该检查请求字典中的所有数据类型。数量、止损、获利和价格应该是浮动值，并记住订单应该是内部
