It is sold as an API and MCP connector with Free, Pro $49, Desk $199 and Enterprise (contact sales) tiers.

Net P&L = (exit − entry) × units − total fees. Enter the applicable venue fees yourself. This tool does not model fills or estimate Sharpe from a single trade. For many trades, use the Sharpe and drawdown calculator.
