Much as I would like to provide clarification, I can only say I originally read things as you do/did.

I believe the distinction here is that in the past the IWM Robot would trade neutral signals, leaving it to Billy to determine whether the trade should be long or short depending on his pivot setups. (I think I have this right.)

So "All Signals" includes those trades as well as the buy/strong buy and sell/strong sell trades; the "Strong Signals" measures only includes buy/strong buy and sell/strong sell signals.

Pascal/Billy need to confirm this, to be sure.
