Closing position with Metatrader5 for Python library

[francesco.re1107]

Hi,

I'm trying to use this library for python.

I've successfully connected to my account and placed an order with this code:

request = { 
        "action": mt5.TRADE_ACTION_DEAL, 
        "symbol": pair, 
        "volume": 0.02, 
        "type": mt5.ORDER_TYPE_SELL, 
        "price": tick.bid, 
        "deviation": 50, 
        "type_time": mt5.ORDER_TIME_GTC, 
        "type_filling": mt5.ORDER_FILLING_RETURN, 
    } 

    # send a trading request 
    result = mt5.order_send(request) 
    if result.retcode != mt5.TRADE_RETCODE_DONE: 
        print("Order failed: {}".format(result.retcode))
    else:
        print(result.order)

But when I want to close that position with the following code, it gives me 10013 error, which means Invalid request

def close(order_ticket):
    request = { 
        "action": mt5.TRADE_ACTION_CLOSE_BY, 
        "volume": 0.01,
        "order": order_ticket,
        "type_filling": mt5.ORDER_FILLING_RETURN, 
    } 

    # send a trading request 
    result = mt5.order_send(request) 
    if result.retcode != mt5.TRADE_RETCODE_DONE: 
        print("Order closing failed: {}".format(result.retcode))
    else:
        print("closed correctly")

I can't figure out how to close positions. Also the docs is not explanatory. 

I would like also to close positions partially.

Thanks

You have to add the position_id (position ticket number) to the 'position' key. 

import pymt5adapter as mt5


def send_order(req, n=5):
    for _ in range(n):
        res = mt5.order_send(req)
        if res.retcode == mt5.TRADE_RETCODE_DONE:
            break
    return res


def main():
    symbol = mt5.symbols_get(function=lambda s: s.trade_mode == mt5.SYMBOL_TRADE_MODE_FULL)[0]
    buy_order = dict(
        action=mt5.TRADE_ACTION_DEAL,
        type=mt5.ORDER_TYPE_BUY,
        symbol=symbol.name,
        price=mt5.symbol_info_tick(symbol.name).ask,
        volume=symbol.volume_min,
        deviation=100,
    )
    result = send_order(buy_order)
    print(result)
    if result.retcode == mt5.TRADE_RETCODE_DONE:
        deal = mt5.history_deals_get(ticket=result.deal)[0]
        position = mt5.positions_get(ticket=deal.position_id)[0]
        close_order = dict(
            action=mt5.TRADE_ACTION_DEAL,
            type=mt5.ORDER_TYPE_SELL,
            price=mt5.symbol_info_tick(symbol.name).bid,
            symbol=position.symbol,
            volume=position.volume,
            position=position.ticket,
        )
        result = send_order(close_order)
        print(result)


if __name__ == "__main__":
    with mt5.connected():
        main()

On a side note you can also try the pymt5adapter package. https://pypi.org/project/pymt5adapter/
