binance trailing stop let you set the price at which your buy or sell orders will be triggered. This feature has two main purposes: to alert you when the price is about to drop or rise and to protect your profit. Trailing stops can be set as a percentage or as a range. The lower the trailing price, the higher the probability of triggering your order. If you want to place a limit order, you can set it to the last price, or a mark price. If the price does not reach the mark price, the trailing stop will still trigger.
