Actually there is a great way to use lagging indicators to trade with. Example you could keep track of how far a price spikes above and below an average before it turns opposite direction. Also those inflection points when failed usually signal the beginning of a momentum move in the same direction.
Agreed. The point is that I accomplish this with my trading plan without indicators. This is not something that is complicated or a convoluted approach but one I have used now for 19 years without modifying it (no need to as it works). I have changed one thing: eliminated Stops.
However, I respect your point made and agree -- perhaps just a different approach. Thanks for the comment.
