If you don't have trouble waiting for your setups then you have the world by the shorties.In my own case, there is not much wait. I generally get 20 trades a day. I am too exhausted to trade all of them. The trading day lasts 14.5 hours. I trade 3 min charts. That is 290 bars a day.
The pattern I described is called 3 push pattern (also called 'wedge') as discussed by Al Brooks in his books. There is not always a climax. The pattern reverses sometimes with leg count. The probability issue in that case is slightly complicated since the previous trend can go for one more leg before a reversal. This can take out the SL. It will force one to re-enter after that 4th push. Further, if there is a channel forming in the previous direction, this pattern builds within a lower time frame and you then have to trade intuitively.
In my original post, the discussion about probability is not specific to this trade. So, I did not delve into the specifics earlier.
Break a leg!
