CLOSE_BY ..?

[Carl Schreiber]

I refer to the article: https://www.mql5.com/en/articles/2299 (from 2016):

New trading constants

Due to the addition of the new Close By operation type, the new trading properties have appeared as well:

• TRADE_ACTION_CLOSE_BY — new trading operation type — close a position by an opposite one.
• ORDER_TYPE_CLOSE_BY — new order type — close a position by an opposite one.
• ORDER_POSITION_BY_ID — new order propertiy — ticket of an opposite position used for closing the current one.
• DEAL_ENTRY_OUT_BY — new deal type — close a position by an opposite one.

My goal (without any specific trading strategy in my mind, but just to see and check what might work) is to place a pending order that partially closes another pending order (after it will have become an open position of course) or to close an open position with a pending order.

SL and TP of a position always close the whole position. It is possible to (partially) close an open position partially with another open position, see Trade.mqh.

Now I would like to have placed pending orders that (partially) close the open position and that I could push up and down depending on the market development - as I said, an academic scenario.

Attached is a test EA tuned on the period D'2022.10.05 00:00' to D'2022.10.06 00:00' and EURUSD so that the StopLimit order does not fail on prices.

There is a nice profit, but I know the price trend - honi soit qui mal y pense ;)

My question: is it possible to use pending orders as kind of SL & TP (how? I failed what ever I tried) to close positions partially?

Or are the 'new' options from 2016 just for queries to the trade history?

PS: Unfortunately MQ makes no difference in their English documentation: order can mean a pending order or any order send to the server :(
