Let’s talk about reduce-only orders.
In one-way position mode, the same buy or sell order can either open or close a position. Reduce-only is used to ensure that an order can only close a position, not open one.
To be honest, I hadn’t noticed this before either: after closing a position manually, don’t forget to check whether any previously placed take-profit or stop-loss orders are still active and need to be canceled.
By the way: $BTC current price 68192.01 (24h -4.36%).
When prices are highly volatile, don’t chase orders. Wait for the price to stabilize before deciding.
