I only meant to close my position—how did I suddenly end up short?
In One-Way Mode, a regular sell order can’t tell whether you mean to “take profit” or “open a short.” It simply follows the order parameters.
For example, suppose you’re holding a 1 BTC long position and have placed a separate regular limit sell order for 1 BTC, intending to exit if the price rises. Later, you manually close your long position, but don’t cancel the old sell order or set it to Reduce-Only. If the order later meets the conditions for execution and margin, it could open a short position you never intended to hold.
According to Binance’s official explanation, Reduce-Only in One-Way Mode ensures an order can only reduce an existing position, not increase it. This restriction means “you can only close out, up to your current position size”—not that the order is guaranteed to be accepted, or that it will execute at a particular price.
This is worth checking carefully for BTC, ETH, and SOL contracts. Regular standalone orders, order groups with linked cancellations, and different position modes may all work differently. Don’t rely only on whether the button says “Take Profit.”
I’d focus on checking whether any open orders remain after the position reaches zero, and whether subsequent orders are allowed to increase exposure. If your exit plan exists only in your head, the system may execute it as your next trade.
