In this final part of the introduction, the speaker discusses the stages of a candletstick pattern. He talks about the three criteria needed before any action is taken. First, there must be a trend (up or down). Secondly, there must be a pattern that has developed. Finally, there must be confirmation in the anticipated direction.
A professional trader does not look for certainty, rather, they look to put a trade on that has the best odds of suceeding.
He talks through a few setups: a bearish reversal pattern, continuation pattern, and sideways trend (should be ignored). He also mentions that a candlestick setup has the most potential on a short term timeframe only, typically from 1 to 6 bars after the setup has been identified and confirmed.
