The goal of the Move Stop Loss To is to create a trailing stop that will only activate when orders are filled.
Will only work if Bybit Pro is up and running on the account and instrument you're trading at the moment your order is filled and network conditions are optimal.
You have a ladder that filled a long position for 100 contracts with an average at 55940.93
Now, you want to take some profits, so you place a limit order at 56000 like this :

Once that order fills, your position will now be 50 contracts and a stop loss is placed at 55941 (above entry)
You can now add another sell order at 56100 that will move your SL at 56000 and so on…
