OCO order

Definition

Two linked orders where filling one cancels the other.

Why it matters

Standard for stop and target pairs, and the safest way to avoid an accidental double position after a fast fill.

Example

A target at $61 and a stop at $57 linked as OCO: when the target fills, the stop cancels automatically, so you are never left with an accidental short.

How to track it in a journal

TradeStack calculates the core performance numbers — win rate, average win and loss, profit factor, expectancy, drawdown and consistency — automatically from imported trades, so oco order stops being something you estimate and becomes something you read.
