What is the MFI API?
The Money Flow Index (MFI) is a volume-weighted RSI that oscillates between 0 and 100. Unlike pure price momentum indicators, MFI factors in trading volume — making it more sensitive to institutional accumulation and distribution. Our API delivers pre-calculated MFI(14) for any symbol and timeframe so your bot gets the signal, not the raw data.

Frequently Asked Questions
What period does MFI use?
We calculate MFI with a 14-period lookback (MFI_14), the standard setting. The calculation uses typical price × volume for each candle sourced from broker terminal data.
How is MFI different from RSI?
RSI uses only price changes. MFI incorporates tick volume, making it a volume-weighted oscillator. When price rises on low volume, MFI climbs less aggressively than RSI — helping distinguish genuine momentum from weak moves.
Can I get historical MFI values?
Yes — use GET /v1/indicator/history with indicator=MFI_14. Starter plan provides up to 30 days on H1+; Pro and Enterprise extend to 45 days.
Which symbols are available?
All symbols active on connected broker terminals — 50+ Forex pairs, XAUUSD, XAGUSD, BTCUSD, and select indices. Query GET /v1/symbols for the live list.
