Pretty easy to see on the hourly chart why the decline stopped where it did today!
I actually have this automated and works well enough on 18 markets. I have found through backtesting you have defined pivot strength, where to start trendline drawing to next defined pivot. Strength of pivot is how many lower highs to the left and right of highest high in so many months then finding where you can start to draw to as your second pivot, I tested for a defined number of bars before I can draw to second pivot, reason for this, too few would show too steep of a trendline and offered too many losses. I never draw trendlines thru bars, not saying shouldn't be done, but backtesting I wanted to have better defined rules.
Method does me well, and also on intraday methods great places to exit trend trades.
