OCO Order

Order Types

どういう意味か

One-Cancels-the-Other: two linked orders where filling or triggering one automatically cancels the other. Used to set both a profit target and a stop at once.

You buy at $100 and place an OCO: a sell limit at $110 (take profit) and a sell stop at $95 (stop loss). If price hits $110 first, the $95 stop is canceled -- and vice versa.

初心者がよくやるミス

Beginners forget to use OCO and end up with an open stop-loss still live after their take-profit filled, accidentally re-entering a short or selling shares they no longer hold.
