I don't think such a trick can be done. I usually only use it once and leave it. Do you also use it for spot trading? or is it more suitable or better used for futures trading?
Why shouldn't that be possible? It is basically a "take profit" where you simply indicate what profit you are already satisfied with ... even if the price is even lower than your target with a classic take profit.
By shifting the limits as he has described, you will definitely exit with a profit. You just have to be careful not to set the limit too close to the current price, at least not with cryptos. These usually fluctuate quite strongly during the day, so a 5% limit may already be too tight, especially with altcoins.
