I usually let the generator do its thing, without locking or chaining because I am looking at certain statistics at the end of the day.
Once we start to use the locks and chains, we are limiting the performance of seeking the best results.
We actually need only a few indicators that are supplied in the installation, the generator will do the rest.... all we have to do is select the best results.
Personally, when I start the generator, I am looking for 6 stratgeies that meet my needs. and I let it run until it serves up the 6. That could take an hour or three days.
My 'secret' goal is to push EA Studio until I can net 3000 pips per day....
