PropSize – TradingView Prop Firm Risk Calculator

Calculate futures position size and risk from your daily-loss and drawdown buffers while using TradingView.

PropSize is a futures position-sizing and risk-estimation tool designed to be used alongside TradingView. It helps traders estimate an appropriate whole-number contract quantity before entering a trade based on their remaining daily-loss and drawdown buffers. Key features: • Manual entry price and stop-loss inputs • LONG and SHORT trade support • Daily-loss and drawdown buffer controls • Percentage-based and fixed-dollar risk sizing • Estimated commission and slippage costs • Stop distance in points and ticks • Estimated risk per contract and total trade risk • Trade feasibility checks • Risk exposure classification • Whole-contract position sizing • Support for selected equity index, energy, and metals futures contracts • Native Chrome Side Panel for use alongside TradingView PropSize uses manual inputs only. It does not automatically read, scrape, or extract TradingView chart data. Your PropSize inputs and preferences are stored locally using Chrome extension storage. The extension does not transmit your locally stored trade and risk inputs to our servers and does not use analytics or remote tracking. PropSize does not connect to brokers or prop firms and does not execute, place, modify, or close trades. PropSize is an educational risk-estimation tool and is not financial advice. Users are responsible for verifying current futures contract specifications, broker fees, prop-firm rules, and account restrictions. PropSize is designed to complement Prop Firm Risk OS.
