No matter how long you wait and how much confirmation you see, a high % of patterns like this will fail. Google the work of Thomas Bulkowski to see from his research how badly most candlestick patterns actually perform.
This means maybe 1 trade in 3 will be a loser so you must always plan what you will do with the losers to keep losses small. Don’t forget to plan what to do with the winners to maximise their profits. Its generally a wasted effort to spend your days trying to find more and more and more reliable entry patterns.
