Order types & TP/SL

Bitnxs supports limit orders, market orders, stop (trigger) orders and take-profit / stop-loss (TP/SL) orders on every perpetual market. Limit orders that rest in the book pay the maker fee; orders that fill immediately pay the taker fee.

What order types does Bitnxs support?

Order type	What it does
Limit	Buys or sells at your price or better. Rests in the order book if not filled.
Market	Fills immediately against the best available prices.
Stop / trigger	Sends an order when the trigger price is reached.
Take-profit (TP)	Closes your position at a profit when the trigger price is reached.
Stop-loss (SL)	Closes your position to limit losses when the trigger price is reached.

Time-in-force options: GTC (rests until filled or cancelled), post-only (rejected if it would cross), IOC (fill what you can, cancel the rest) and FOK (all-or-nothing). Market orders never rest; their limit price acts as a price-protection band. Reduce-only orders can only shrink a position. See API order types.

How do take-profit and stop-loss orders work?

TP/SL orders are evaluated against the oracle price. For example, a stop-loss on a long position fires when the oracle price is at or below your trigger price and then submits a reduce-only sell, so it can only shrink your position, never flip it.

TP/SL trigger orders sit off-book and fire as reduce-only market orders when the oracle price crosses the trigger level (see trigger rules).

Should I use limit or market orders?

Use limit orders when you want a specific price and the lower maker fee (0.02%). Use market orders when speed matters more than price (taker fee 0.05%).

FAQ

What is a reduce-only order? An order that can only decrease an existing position.
