How the math works & Constants:

This calculator reverse-engineers the math so your Price Loss + Entry Fee + Stop Loss Fee equals your target risk.
Sizing assumes no slippage or spread change, and floors to 0.001 lots (meaning your actual total loss will slightly under-risk vs target).
Trading fees (Fee per Side) are included in the sizing.
Swap fees (typically 0.05% on positions held at 0000 UTC) are not included in sizing.
