"Those studying the market..are studying what someone said instead of what market said about itself" Richard Wyckoff
As a trader, we have to trust our system and follow its orders. A setup is an 'order' from the market. When you recognize it, you act on it - you don't agree or disagree, for one reason or another. You just take it.You cannot know until afterwards whether it was a good one. Sometimes you may have a hunch, but that is best ignored, if you have a reliable trading system. The research has already been done. Don't mix R&D with trading - they should be kept completely apart.
