Timeframe M1 · unit norm
The Negative Directional Indicator measures how much of the recent price range is attributable to downward movement - normalized by the average true range.
Above 25: sellers are meaningfully driving price lower within each bar. Below 20: sellers are relatively passive. High −DI with high ADX = a confirmed downtrend.
Where +DI measures buyers' work, −DI measures sellers' work. A big −DI means sellers have been consistently hammering new lows.
Janira computes −DI 14 (M1) 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.
