On-Balance Volume accumulates volume on up-bars and subtracts it on down-bars. The 10-bar slope of that cumulative series, divided by total session volume, measures how fast net participation is rising or falling right now.
Positive values signal that more volume is flowing into up-bars than down-bars over the last ten candles. Negative values signal the opposite. Values near zero indicate indecision or a volume-neutral drift.
Imagine a scoreboard: every time a candle closes higher, add its trading volume; when it closes lower, subtract it. The slope tells you whether that scoreboard is rising or falling quickly - fast rising means buyers are louder, fast falling means sellers dominate.
Janira computes OBV Slope (10-bar, normalized) deterministically from live price action, the same way for every reading - no discretion, no hidden weighting. This page explains the method; it is not a live reading and not advice.
