Updated Position Size Calculator - Fixed Dollar amount, point value ATR

Hello Traders,
A very simple code aiming to help you size your position, according to the amount you're accepting to lose AND the current volatility ATR.
Why is it important to use ATR size ? Markets move, and having fixed stoploss values will lead to getting stopped out in case of volatility increase.
You also need to size down your trades in case of more volatily, as more points can be taken or lost.
Hope it helps!
