How much does it cost to reverse a futures position?

A reverse is two fills, not one. OKX's help center describes its reverse button as closing an existing position and immediately opening an opposite position with the same quantity, and BingX's Trigger Reverse closes the position at the market price and opens an equivalent one in the opposite direction. Neither exchange lists a separate reverse fee — but each leg is a trade, so the normal trading fee applies to the close and again to the new open: roughly twice the position value × your rate.

What a reverse actually does

OKX: the reverse button closes an existing position and immediately opens an opposite position with the same quantity in a single action. OKX notes that a smaller reverse position may be opened if available margin is insufficient, that successful execution is not guaranteed, and — in its one-tap reverse guide — that the feature is available only in One-Way Mode.
BingX: Trigger Reverse waits for a trigger price (last, mark or index price), then closes the existing position at the market price and opens an equivalent position in the opposite direction, using the maximum margin available if margin is short.

One click, two orders. If you are long 1 BTC and reverse, 1 BTC is sold to close and another 1 BTC is sold to open the short — 2 BTC of fills in total.

How the fee adds up

Futures trading fees are charged on each fill as position value × fee rate (how futures fees are calculated). A reverse therefore pays:

the fee on closing the old position, and
the fee on opening the new one,

each on roughly the same position value. Both legs execute straight away against the order book, which is how taker fills work (maker vs taker fees), so plan for the taker rate on both — the standard taker rate on loweef's partner exchanges is 0.04–0.05% before VIP discounts. Your trade history shows the actual rate charged on each leg.

The market close can also fill away from the price you saw, especially in fast markets (slippage vs trading fee), and the new position starts paying or receiving funding from the next funding time (what a funding fee is).

Reverse vs doing it yourself

Speed: the button saves a step, which matters in a fast move.
Cost: the same two legs are needed either way. Doing it manually lets you use limit orders for one or both legs, which can fill at the maker rate if they rest on the book first — at the risk of not filling.
Size: a reverse opens the same size. If margin is short, OKX may open a smaller position and BingX uses the maximum margin available, so check the result.

In hedge mode an order in the opposite direction opens a second position instead of closing the first, so it is not a reverse at all — see hedge mode trading fees.

Reverses and fee rebates

A fee rebate is a share of the trading fees your account pays, so both legs of a reverse count like any other fills — a strategy that flips often generates twice the fills of one that only closes. Current figures on loweef's partner exchanges:

Exchange	Total rate	Welcome boost	Effective taker
AlphaX	65%	—	0.0175%
BingX	60%	70%	0.0200%
OKX	50%	60%	0.0250%
MEXC	55%	65%	0.0180%

Figures are estimates based on published fee schedules; actual costs depend on your VIP tier, whether each leg fills as maker or taker, and slippage.

Frequently asked questions

Is there a separate fee for the reverse button?

Neither OKX's help center nor BingX's Trigger Reverse description lists one. The cost is the normal trading fee on the two fills the reverse creates: closing the old position and opening the new one.

Why did reversing cost about twice a normal close?

Because it is two trades. A reverse closes your position and opens the opposite one at the same size, so you pay the trading fee on roughly twice the position value.

Can I reverse at the maker rate?

A one-click reverse is built to execute straight away, so expect taker fills. Placing the close and the new open yourself as limit orders that rest on the book can get the maker rate, but they may not fill.
