如何从 Python 关闭 MT5 订单？答案

【问题标题】：How Close an MT5 Order from Python?如何从 Python 关闭 MT5 订单？

【问题描述】：

我正在尝试通过 MT5-python API 从 python 脚本向我的 MT5 终端发送订单。

我可以开仓，但如何通过 Python mt5-API 平仓？

我这样开一张买票：

import MetaTrader5 as mt5 
lot = 0.1
request = {
"action": mt5.TRADE_ACTION_DEAL,
"symbol": symbol,
"volume": lot,
"type": mt5.ORDER_TYPE_BUY,
"price": price,
.....
"type_time": mt5.ORDER_TIME_GTC,
 "type_filling": mt5.ORDER_FILLING_RETURN,
}

enter copoint = mt5.symbol_info(symbol).point

但是发送“关闭”的命令和形式是什么？

非常感谢！

【解决方案1】：

更简单的方法

mt5.Close(symbol,ticket=ticket)

注意：ticket 与 position_id 相同

【解决方案2】：

订单的结构是一样的，只是在收盘时，你必须指定你从第一个订单返回的结果对象中得到的position_id。显然，如果关闭一个买单，关闭请求就是一个卖单。这是您可以用来进行买卖的代码。

import MetaTrader5 as mt5


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

def get_info(symbol):
    '''https://www.mql5.com/en/docs/integration/python_metatrader5/mt5symbolinfo_py
    '''
    # get symbol properties
    info=mt5.symbol_info(symbol)
    return info

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 = get_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

    buy_request = {
        "action": mt5.TRADE_ACTION_DEAL,

        "volume": lot,
        "type": trade_type,
        "price": price,
        "sl": price - sl_points * point,

    }
    # send a trading request
    result = mt5.order_send(buy_request)        
    return result, buy_request 

def close_trade(action, buy_request, result, deviation):
    '''https://www.mql5.com/en/docs/integration/python_metatrader5/mt5ordersend_py

    # create a close request

        price = mt5.symbol_info_tick(symbol).bid
    position_id=result.order
    lot = buy_request['volume']

    close_request={
        "action": mt5.TRADE_ACTION_DEAL,
        "symbol": symbol,
        "volume": lot,

        "type_filling": mt5.ORDER_FILLING_RETURN,
    }
    # send a close request
    result=mt5.order_send(close_request)


# This is how I would execute the order
result, buy_request = open_trade('buy', 'USDJPY', 0.1, 50, 50, 10)
close_trade('sell', buy_request, result, 10)
