Awesome
and his strategies make some good money. I know because I have copied some of his stuff.
Notice that all of them are related to a moving average of some sort.
Some writers say that moving averages and donchian systems have been the best over the long haul, and that is why I focus on these indicators in my strategies.
Not everyone can do that ........ because you have to be of a certain age to use these. LOL
I have made money with each of these, I have not yet learned how to make money with donchian.
In any event, for my purposes FSBPro has enough indicators and tools to provide the basis for many profitable strategies.
