How many times are we reminded to "add this to your trading arsenal"? NG, IMO. When I was a kid I had indicators for up, down and sideways markets, and anything that I could invent to be
"sure" that all was well before taking a trade. It was like preparing a boat for a voyage; prepare for everything. The boat will never leave the dock!
A successful trader needs only one thing to know when time and price are out of balance and that a reversal will follow. Not a lagging indicator. Wolfe Wave practitioners know this in advance.
Old saying: Beware of the man with one gun, he knows how to use it.
