I think there's a strategy to avoid this instead of using the stop-loss why not use isolated one with low margin and adjust the leverage to point your liquidation to the stop-loss you want. This would prevent to lose more than using the stop-loss I saw many traders doing this on very volatile new coins to avoid that issue.
Now, I see why they do that than using stop-loss.
It can work but sometime you can get liquidated when the margin could still mantain the unrealized loss.
With future these kind of things always irks me, because apparently there's no foolproof way to prevent from excessive loss caused by market volatility. It is what it is.
That's exactly why we choose isolated and your stop loss is your liquidation.
Meaning only the margin amount you would lose if its liquidated no further losses because it is liquidated unlike if you set a SL if there a slipage there's a possibility you could lose more than the SL you set.
Excessive loss? You didn't get what I mean that's why I choose isolated than cross is to avoid that issue and use your liquidation as your SL. You just need to adjust the leverage to adjust your liquidation.
