The problem it fixes
Closing a position means finding someone to take the other side of it. Usually that happens instantly and invisibly. Sometimes it does not: a large position in a thin market, a fast move, or a quiet session for that asset class can all mean the liquidity available at that moment is smaller than the size you are trying to close.
Previously the close would partially fill and stop, leaving you holding a remainder you had to notice and act on. That is a bad moment to be handed a manual task, the reason liquidity is thin is usually that something is happening, and the reason you are closing is usually that you want to be out of it.
The old workaround was to click Close repeatedly, each click taking whatever liquidity had returned since the last one. The new behaviour does exactly that, automatically, without you sitting over it.
What it does not change
It is not a fill guarantee. The retry mechanism works through available liquidity as it appears. It does not create liquidity, and it does not control the price of each fill. A position closed across several retries in a moving market will close at several different prices, and the blended result may be worse than the price you saw when you clicked.
It does not remove the reason for the retry. If a position routinely needs multiple attempts to close, that is telling you the size is large relative to the liquidity in that market, which is a sizing consideration for the next trade, not a platform issue.
It does not affect whether you are allowed to close. Closing or reducing a position is never blocked on Ouinex, regardless of free margin or margin call state. The retry is about execution, not permission.
What you will see
Click Close and, in the ordinary case, the position closes and disappears. In the case where liquidity is short, the position will close over a few moments as the retries work through it rather than all at once.
If a position is still showing after you have closed it, give it a moment before clicking again, the retry may already be working. The position info panel shows the live quantity, which is the reliable way to see what is actually left.
FAQ
I clicked Close but my position did not close in one go. What happens? Ouinex retries automatically in the background, up to 50 times, until the position is fully closed. There is nothing to do on your side, no need to click Close again or to submit the remaining quantity manually.
How many times does Ouinex retry? Up to 50 attempts. In practice a position that cannot be closed within that many attempts is facing a genuine and sustained absence of liquidity in that market.
Will the retries all fill at the same price? Not necessarily. Each attempt takes the liquidity available at that moment, so in a moving market the fills can happen at different prices and the blended close price may differ from the price shown when you clicked.
Does this work on partial closes too? The retry applies to closing the position. For a deliberate partial exit, use the partial close function, which closes a quantity you specify.
The bottom line
A close that does not complete instantly is now handled for you rather than handed back to you. Wait a moment before clicking again, check the position info panel for the live quantity, and treat a position that consistently needs multiple attempts as a signal about size rather than about the platform.
