Calculation notes
- Needs volume confirmed by the exchange. On data sources that cannot confirm it, TraderAI keeps this indicator unavailable instead of estimating volume.
- Explicit multiplier times high-low divided by observed spot base volume, in price per base-volume unit. Zero volume is unavailable; a flat range with positive volume is zero. This is not Money Flow Index and does not predict price direction.
