MEXC OCO Order: One-Cancels-the-Other, Explained Honestly

What OCO Actually Means

One-Cancels-the-Other links two orders — typically a limit order above the current price and a stop-limit order below it — so that filling one automatically cancels the other. It's a way to set a take-profit and a stop-loss at the same time without babysitting the screen.

How OCO Works on MEXC

MEXC's spot form supports conditional order types, but on freshly listed pairs the real issue isn't the ticket type — it's whether either leg of an OCO can actually fill at a reasonable price in a thin book.

Setting Up the Two Legs

Set the profit-taking limit price above the market and the stop-limit trigger below it (for a long position), matching your actual risk tolerance rather than a round number that feels satisfying.

If MEXC Doesn't Offer a Single OCO Ticket

Two separate conditional orders can approximate the same behavior, but you'll need to manually cancel the other leg once one fills — MEXC's interface may or may not do that automatically, so test it with a small size first before relying on it for a real position.

Fees on Both Legs

Whichever leg fills gets billed MEXC's normal maker or taker rate depending on how it executes — an OCO ticket doesn't carry a special combined fee.

• Confirm which leg actually filled
• Confirm the other leg was cancelled, don't assume
• Check the fee charged matches maker or taker as expected
