Aha! I think I figured this out. The reason that the chart trades look different when changing the strategy from using enterLong() to reverseLong() is because I've been re-training it between those changes.

When re-training, apparently it gets different parameters that cause it to actually trade differently.

This light-bulb went off in my head when I accidentally forgot to re-train after flipping the strategy. I just clicked Test and then Result... and doing this (ie, using same parameter set) shows trading throughout (or not) consistently during that 2009 period.

Now I feel accomplished LOL. I can say the week hasn't been a waste for my ongoing Zorro knowledge...
