The best price refers to the TP/SL order prices that are easiest to trade after placing an order in the current market. Usually, market orders will always take precedence over limit orders. For limit orders:
- When closing a short position, the best price is the highest price of your TP/SL orders
Example: Assume currently, the last price is 100 USDT and User A submits 3 TP/SL orders at 80 (#1), 70 (#2), and 60 (#3) to close their short positions. Then the best TP/SL price for user A is 80 (#1).
- When closing a long position, the best price is the lowest price of your TP/SL orders
Example: Assume currently, the last price is 100 USDT and User A submits 3 TP/SL orders at 120 (#1), 130 (#2), and 140 (#3) to close their long positions. Then the best TP/SL price for user A is 120 (#1).
