Opportunity BasketRiskGuard: Broker-Native Position Sizing Plugin
A lightweight plugin that integrates directly into popular brokers' trading platforms (Interactive Brokers, TD Ameritrade, TradeStation, Lightspeed) and automatically calculates position size in real-time as traders enter stop-loss and risk percentage. The plugin pulls live account balance, calculates max shares/contracts based on the trader's risk formula (Account Size × Risk % ÷ Stop Distance), and displays the safe position size before order entry—preventing oversizing at the moment of execution.

Traders struggle to consistently calculate and manage risk per trade without manual spreadsheet errorsActive traders and investors manually calculate risk per trade using spreadsheets or mental math, leading to inconsistent position sizing, blown accounts, and missed opportunities. Current solutions lack integrated, real-time risk calculation tied to their actual trading accounts and market data. Traders need a reliable system that automatically calculates optimal position size based on account size, stop loss, and risk percentage to prevent catastrophic losses.
