Entry is USD 100 and the assumed stop fill is USD 95. With USD 500 of planned risk, would you buy 5 units or 100 units?
Answer: 100 units. Each unit has USD 5 of assumed loss, so 500 / 5 = 100. Five units would risk USD 25 under the same assumption.
This is cash-position arithmetic before costs. Contract multipliers, gaps and slippage need separate treatment.
