Reporting Calculator Discrepancies
Our calculators are designed to model standard perpetual futures arithmetic accurately. However, exchange specifications vary significantly across venues (e.g., maintenance margin rate schedules, contract multipliers, index calculation rules).
If you identify a calculation discrepancy between our tools and your exchange’s order panel, please include the following details in your message:
- Calculator Tool: The specific tool used on calculator.becofree.org
- Exchange & Asset: The trading venue and contract name (e.g., Binance BTCUSDT Linear Perpetual)
- Inputs & Parameters: Account equity, entry price, stop-loss price, margin mode (isolated/cross), and leverage
- Observed Difference: The output generated by our calculator versus the exchange’s displayed order preview
This information allows our team to review the contract specifications and update our underlying mathematical models promptly.
Communication Guidelines & Response Time
- Response Time: We endeavor to review and reply to all legitimate inquiries within 24 to 48 business hours.
- No Financial Advice: Please note that Becofree is an educational and analytical research platform. We strictly do not provide personalized financial advice, portfolio evaluations, or trading signals. Inquiries requesting market forecasts or trade recommendations will not receive a response.
