Drawing a Horizontal Line is the most easiest job in Trading.....
Red Lines: Pivots on a larger TimeFrame (47min/60min).... Amused by me mentioning a TF of 47min.... It is just to maintain data integrity... as I also give importance to volumes.... In one Trading Session we get 8 candles of 47-min....
Yellow Lines: Two or more Pivots on a smaller TimeFrame (5min/15min)..... No rigid rule, but when you see price taking a turn from a particular area persistently on a smaller TF....
If you have the data..... draw these lines yourself and then look at my charts.... They would look quite similar
