Shouldn't that read instead:
If total net profits >= 0
Profit/Loss index= (Total net profits + interest+ open position value) / amount of win trades
If total net profits < 0 (note that I also dropped the minus-sign in front of "Total net profits")
Profit/Loss index= (Total net profits + Open position value) / amount of losing trades
And how does this gets into a range of -100 to +100? There must be some mathematical knowledge only
available to Equis <G>
Just curious,
