Notes:
* PF     - average profits expected per trade:
           >  1.0: $1 invested returns > $1 (profitable)
           =  1.0: $1 invested returns   $1 (breakeven)
           <  1.0: $1 invested returns < $1 (loss).
 
* TScore - observed probability due to chance at 95% CI:
           >  1.645: not just dumb luck
           <= 1.645: dumb luck.
 
* ZScore - duration of Win/Lose streaks:
           >=  1.645: shorter duration
           <= -1.645: longer duration.
 
* Optf   - optimal percent of capital to invest:
           >  0: might be worthy to invest
           <= 0: save your money.
