Combining standard 1st touch and breakout theory, one can see that blindly trading only first touch of a line before and after breakouts as support or resistance would have yielded a fair bit of win, although not 100%. See how a strong intraday break leads to retracement back to the lines to bounce for a short term extreme? One should not trade multiple times within that daily range in the event of a break to minimize risk as much as possible, technically- the picture show a whipsaw area after the main initial touch on the longer timeframes. With that said, the long term lines are expected for the extremes of a daily range but also combines multi timeframe analysis along those points. So it automatically prices in the intraday and the long term points, thus technically giving a greater chance of a reaction.
