If you ask why I would do that, imagine if there were a resistance coming and I want to buy only if this resistance got broken and price went higher
Pionex limit order and smart trade bot, when I input a buy price higher than the current price, they buy immediately at the current price
Answer
Putting a lmit order above current price means you are betting the market would go down but im case you get it wroung and market grows up you would like to be a part of the trade hence you use a stop buy. Go to trade on the app , go to bot , create bot , look out for STOP LIMit bot then set your limit buy order.
