has anyone used trade with precision?

I have checked out their stuff from time to time, and a few years ago I went to a presentation by Nick McDonald who is the spearhead of TWP..
The guy would appear to do quite well from the occasional times I have seen his videos , and then reviewed his comments after time had passed.
He is very technical , with a methodical method. The main point I've taken from his videos is the importance of establishing support/resistance levels on multiple time frames
