Not sure I understand the point of trailing stop orders in their current state.

What is the point of setting a limit price in advance. The whole point of trailing stop imo is to maximize profit, I would expect the limit price to be the trailing stop price. The limit price should be dynamic.

i.e. if I set my trailing delta to 5% I expect my limit price to rise with the price and if the price goes against me by 5% then an order would be executed at market price.

e.g. Using the Binance example, I would expect my position to be sold at market price (~$17100) once the market price crosses the trailing stop price.
