A small mathematical error has been made here.
However, when we look at large percentage short position gains or in total, it can cause huge calculation errors.
Short position profit is calculated as follows:
Profit Percent = pp
Short Position Profit = ((100 / (100 - pp )) - 1 ) * 100
Short Position Profit = ((100/98.47) - 1 ) * 100
Short Position Profit = (0.0155) * 100 = 1.55 (percent)
Total Profit = (Lev * Short Position Profit * Position Size) / 100 =
= (33 * 1.55 * 3) / 100 = 1.5345
Our new capital = 100 + 1.5345 = 101.534
