Bernard,
a.
P = 1 + (SellPrice - BuyPrice) / BuyPrice;
is EXACTLY equivalent to
P=SellPrice/BuyPrice;
because
P=1+(S-B)/B=(B+S-B)/B=S/B
b.
What is CP in words?
This will help perhaps to continue.
If I take verbatim the
CP = CP * P;
means
CP-CP*P=0, IE
CP*(1-P)=0, IE
either CP=0 or P=1
Better say what is CP in words.
