How these tools are built
- Browser-side math. Calculations run on your device. The tools do not send your inputs anywhere.
- You supply the market data. There are no live prices or exchange rates. Where a conversion rate matters, you type it, so you know where it came from.
- Formulas are shown. Every page lists its formula, a worked example that matches the default inputs, and its limitations.
- Brokers differ. Contract sizes, fees, margin rules and liquidation methods vary. Treat results as planning figures and check them against your platform.
