Staying firm to the decision you have taken should do the trick, sure you might alter your trades at times and come out successfully some times but that's not a guarantee you can carry-out such alterations simultaneously and be profitable all the times. Doing so also means you didn't carry-out your TA perfectly and would start making you loss confidence in yourself.

The market is under the influence of manipulators, the whales know their games can trick gullible traders to falling victims to their games so they do this occasionally. You just have to stick to you plans and if they don't play out as you have expected you work on yourself in improving your chart reading skills/interpretation.
