order_check

检查是否有足够的资金执行所需的交易操作。检查结果以MqlTradeCheckResult结构返回。

order_check(
   request      // 请求结构
   );

参数

request: [in] 描述所需交易操作的MqlTradeRequest类型结构。所需的未命名参数。下面描述了填写请求和枚举内容的示例。

返回值

检查结果以MqlTradeCheckResult结构返回。回答中的request字段包含传递到order_check()的交易请求的结构。

注意

成功发送请求不代表所请求的交易操作就可成功执行。order_check函数类似于OrderCheck。

TRADE_REQUEST_ACTIONS

ID	描述
TRADE_ACTION_DEAL	以指定参数（设置市价单）下现价交易订单。
TRADE_ACTION_PENDING	在指定条件下（挂单）下执行交易订单，
TRADE_ACTION_SLTP	更改持仓止损和止盈
TRADE_ACTION_MODIFY	更改之前所下交易订单的参数
TRADE_ACTION_REMOVE	删除之前所下的挂单
TRADE_ACTION_CLOSE_BY	反向平仓

ORDER_TYPE_FILLING

ID	描述
ORDER_FILLING_FOK	这个执行规则意味着一笔订单只能按照指定的交易量执行。如果金融产品的必要数额目前在市场上不能满足，则该订单将不会被执行。所需交易量可以由几个可用报价组成。
ORDER_FILLING_IOC	在订单中规定的交易量范围内，以市场最大交易量执行交易的协议。如果不能完全成交，则将执行可用交易量的订单，并取消其余交易量。
ORDER_FILLING_RETURN	这个规则只适用于市价单（ORDER_TYPE_BUY和ORDER_TYPE_SELL）、limit和stop limit订单（ORDER_TYPE_BUY_LIMIT、ORDER_TYPE_SELL_LIMIT、 ORDER_TYPE_BUY_STOP_LIMIT和ORDER_TYPE_SELL_STOP_LIMIT）以及市价执行和交易所执行模式的交易品种。如果部分成交，则剩余交易量的订单不会被取消，等待进一步处理。在激活ORDER_TYPE_BUY_STOP_LIMIT和ORDER_TYPE_SELL_STOP_LIMIT订单期间，将创建一个对应的限价单ORDER_TYPE_BUY_LIMIT/ORDER_TYPE_SELL_LIMIT，并使用ORDER_FILLING_RETURN类型。

ORDER_TYPE_TIME

ID	描述
ORDER_TIME_GTC	订单将一直保留在队列中，直到手动取消
ORDER_TIME_DAY	订单仅在当前交易日有效
ORDER_TIME_SPECIFIED	订单在指定日期之前有效
ORDER_TIME_SPECIFIED_DAY	订单在指定日23:59:59之前有效。如果此时间不在交易时段内，到期将在最近的交易时间内处理。

例如：

import MetaTrader5 as mt5
# display data on the MetaTrader 5 package
print("MetaTrader5 package author: ",mt5.__author__)
print("MetaTrader5 package version: ",mt5.__version__)

# establish connection to MetaTrader 5 terminal
if not mt5.initialize():
    print("initialize() failed, error code =",mt5.last_error())
    quit()

# get account currency
account_currency=mt5.account_info().currency
print("Account сurrency:",account_currency)

# 准备请求结构
symbol="USDJPY"
symbol_info = mt5.symbol_info(symbol)
if symbol_info is None:
    print(symbol, "not found, can not call order_check()")
    mt5.shutdown()
    quit()

# 如果市场报价中没有此交易品种，请添加
if not symbol_info.visible:
    print(symbol, "is not visible, trying to switch on")
    if not mt5.symbol_select(symbol,True):
        print("symbol_select({}}) failed, exit",symbol)
        mt5.shutdown()
        quit()

# prepare the request
point=mt5.symbol_info(symbol).point

    "tp": mt5.symbol_info_tick(symbol).ask+100*point,
    "deviation": 10,
    "magic": 234000,
    "comment": "python script",
    "type_time": mt5.ORDER_TIME_GTC,
    "type_filling": mt5.ORDER_FILLING_RETURN,
}

# 执行检查并显示结果'按原状'
result = mt5.order_check(request)
print(result);
# request the result as a dictionary and display it element by element
result_dict=result._asdict()
for field in result_dict.keys():
    print("   {}={}".format(field,result_dict[field]))
    # if this is a trading request structure, display it element by element as well
    if field=="request":
        traderequest_dict=result_dict[field]._asdict()
        for tradereq_filed in traderequest_dict:
            print("       traderequest: {}={}".format(tradereq_filed,traderequest_dict[tradereq_filed]))

# shut down connection to the MetaTrader 5 terminal
mt5.shutdown()
