Hi RM
The short answer is about 2000 Chart hours last year trading the M5 chart during the London Session, but studying the reversal points on M1.
I have also had many discussions with seriously good Forex and Future traders over candle patterns at the end of a trend. The one above is know as a 3 bar reversal and I also seek out 123's and especially if it ends with a 2B. I trade the flow of the market and aim to enter my trades at point of accumulation after REJECTION has occurred . I used to use normal market orders but last years experience has proven to be that Limited BUY or SELL orders placed within the accumulation zone in the direction of the greater trend is the way to go. Its actually really easy to trade this way.
Here is an example on this weeks trade I got - Sell at Accumulation point in the direction of a proven trend.
