I have quite a few strategies, yes.
Initially, years ago, I used only a few.... recently, I changed that to quite a few more than a few.
Sleytus was good enough to develp and share his application 'MT4-Tracker' which allows us to analyze the performance of, I guess, an unlimited number of strategies with only a few mouse clicks. That changed the game.
Then he shared his 'Portrfolio Maker' app which allows many strategies to be compiled into 1 EA, thereby increasing the capacity of Metatrader4 tremendously.
So...... I spend a lot of time generating new strategies each day, trying different things and then forward testing them.
I do not have a count of the strategies that I am testing, I know that a couple people have more than 1,000.
Use FSBPro to the fullest and test every thing that you can invent, it is well worth the effort.
