Data sources
Three things to understand about where numbers come from on this platform — and where they do not.
Calculators & tools
Every calculator on TradeBien runs entirely on inputs the reader supplies. Pip value, margin requirement, spread cost, leverage exposure — none of these outputs depend on a live price feed. The math is deterministic: given the inputs, the result is exact. No external data source is involved in any calculation.
Reference rates
The Pre-Trade Console displays indicative mid-market reference rates for key instruments. These rates are maintained editorially and updated periodically. They are not streaming quotes, not broker prices, and not executable rates. Their purpose is to give the calculator panels a realistic starting point — the reader supplies or adjusts the actual rate they intend to trade.
What is not shown
Broker-specific spreads are not quoted as universal figures. Spread varies by broker, account type, and market conditions — any single figure would mislead a reader on a different platform. Real-time executable prices are not displayed. Historical price archives are not stored or presented beyond what individual educational examples require.
