Turtle Trading Risk Adjusted Position Size Calculator

Turtle Trading Risk Adjusted Position Size Calculator

Hello Traders !

Turtle Trading Risk Adjustment Calculator (inspired by the Turtle Traders Position sizing methods) aims to objectively help day traders allocate the appropriate position size per trade by scaling different instruments by their risk, as measured by their volatility via the ATR (default - Average of 14 period True Range). By doing so This volatility-based position sizing method normalizes risk across different asset classes.

Understanding The formula


Formula U normalizes positions sizes among any non FX asset, by representing a standard unit of risk as a fraction of volatility adjusted by a risk coefficient (note higher risk coeff values (high uncertainty) will lead to lower trade capital allocation i.e lower position size - Varying the risk coefficient is relevant in expressing uncertainty) and scaled to ones trading account size relative to 1 contract of the asset to be traded, This is referred to as the Dollar volatility, formula D.

Dollar volatility is a bit confusing but in essence it is simply a factor of the asset price such that quantity sums to ones Trading account balance or how many times larger ones trading account is than the assets current market price, or more formally The amount of value a $1 change in the contract would impact your trading account given you are current trading all you account equity.

Formula TVPP is my own adaptation of the Turtle Trading Position Sizing formulas and the standard value per pip formula adjusted for volatility, this iteration has the same logic as stated above although the formulas vary.
