Sharing this idea as a reference to my primary HTF view - the chart was going to be too messy otherwise.
I don't have much experience in trading harmonics at all, but often I keep an eye on them as they respect fibs levels I trade a lot.
Also, maybe just a personal observation, but when i find it more difficult to trade, and it takes ages for the price to move in certain directions, there is probably a harmonic in play.
FVGs, OBs, algo levels and speed fan confluence as well. Trade safe :)
