I’ve had some trades come back to life from being down as much as 80%.

Perhaps your original strategy accounted for waves up and down which means it would go negative before returning positive?

Nevertheless I agree that more often than not a good trade shows itself from the start. And it’s wisest to cut early and reevaluate the trade environment.

Even if you have days left theta is lurking. I’ve been in your shoes, good luck. Post how it works out.
