DislikedI've been taking a look at this CI indicator this weekend and I'm really liking it compared to my usual RSI....Ignored
Good question. If the BB is close to flat or if price is hitting a 'level' (in the chart posted by you 1.2934 was the daily high 22 July) then I would enter at that peak/level, if not then better safe than sorry and wait for price action to confirm the reversal.
In the example posted I had forgotten about the 22 July high and the 5min doji that conformed with the trendline formed by the two previous highs was good enough confirmation. But as a rule I wouldn't wait for 5min bars to close.
I hope that answers the question.
