After accepting a loss from a trade you thought was going to be a good one, ask yourself this question, "Is the structure, bias, and context still intact?" If so, stay with the bias. Look for Change Control the second time and a possible re-entry.
Now, not every single time after losing do you immediately just want to rush and re-enter. There will be plenty of losing trades where you just have to accept that the chart isn't doing what you thought or maybe you're in doubt and it's best to walk away. (Always remember the quote, "When in doubt, stay out".)
In this specific recap on /RTY Futures, the initial trade was a loser but the bias, content, and context was still there and all we had to do was wait for the next pattern of change control for 2nd entry.
