How to use ORDER_TYPE_CLOSE_BY in Python ?

New comment
 

Hi,

request = {
                "action": mt5.ORDER_TYPE_CLOSE_BY,
                "symbol": 'USDEUR',
                "volume": 2,
                'position': 123456,
		'position_by':???,


               # "price": 0.9,
                 "sl":0.9,
}


                
                }
result = mt5.order_send(request)


how can I open an opposite position with ORDER_TYPE_CLOSE_BY using Python?

Error is always 13200 failed cancel order #0 buy 0 at market [Invalid request] regardless of what inputs I with the request send.

According to the mql5 documentation I need  request.position_by=PositionGetInteger(POSITION_TICKET)

However in the python module, the function PositionGetInteger doesnt exist!

Using a random number or converting the position_ticket into int() doesnt work apparently.

And let's say there is a way to use it...how to combine it with Pending Stop-Orders or Stop Loss?

So what I actually want to do is, once a position hits the StopLoss, I want to open an opposite position.

I know, I could just close one position with a StopLoss and have another opposite pending Stopp-Order ready on the same price, but I want to save the spread (if it is possible like suggested on hedging accounts).

You cannot "open" a position using closeby. Closeby is to be used when you already have offsetting orders open on a hedging account and you need to reconcile them as one order closing other. 

import MetaTrader5 as mt5
import pprint


def closeby_all(symbol, **kwargs):
    results = kwargs.get('results', [])
    positions = mt5.positions_get(symbol=symbol)
    it = iter(positions)
    try:
        first_position = next(it)
        second_position = next(p for p in it if p.type != first_position.type)
    except StopIteration:
        return (True, results)
    res = mt5.order_send(dict(
        action=mt5.TRADE_ACTION_CLOSE_BY,
        position=first_position.identifier,
        position_by=second_position.identifier
    ))
    results.append(res)
    if res.retcode == mt5.TRADE_RETCODE_DONE:
        return closeby_all(symbol, results=results)
    else:
        return (False, results)


def main():
    account = mt5.account_info()
    assert account.margin_mode == mt5.ACCOUNT_MARGIN_MODE_RETAIL_HEDGING
    symbol = mt5.symbol_info('EURUSD')
    tick = mt5.symbol_info_tick(symbol.name)
    buy_req = {
        'action'   : mt5.TRADE_ACTION_DEAL,
        'type'     : mt5.ORDER_TYPE_BUY,
        'symbol'   : 'EURUSD',
        'volume'   : 0.1,
        'price'    : tick.ask,
        'deviation': 200,
    }
    sell_req = {
        **buy_req,
        'type' : mt5.ORDER_TYPE_SELL,
        'price': tick.bid

    }
    for order in [buy_req, sell_req]:
        mt5.order_send(order)

    is_done, trade_results = closeby_all(symbol.name)
    for res in trade_results:
        pprint.pp(res._asdict())


if __name__ == '__main__':
    try:
        assert mt5.initialize(), f'Failed to initialized: {mt5.last_error()}'
        main()
    finally:
        mt5.shutdown()
 
Aha, thanks for the code! Seems I totally misunderstood, what CloseBy means.
