Overview
Forex PS queries the 5-minute closing price of a user-configurable conversion currency pair using a security call to convert risk across currencies. The script computes the converted risk per pip and plots the final lot size value directly as an overlay on the main price chart. The account currency, risk amount, and stop-loss distance are fixed in the code, and plotting lot units directly over price action distorts the vertical price scale.
