Data sources
Three things to understand about where numbers come from on this platform — and where they do not.
Calculators & tools
The interactive calculators on TradeBien run entirely on inputs the reader supplies, and the spread cost and leverage risk pages work through a fixed example with the method shown. 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 change only through a reviewed update to the site. 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.
