The stochastic %K locates the current close within the high-low range of the last 14 bars and expresses it as a percentage. Here it is shifted by −50 so that 0 means 'exactly in the middle of the 14-bar range'.
A reading of +40 (raw K = 90) means the close is near the top of the 14-bar range - buyers have pushed price close to the recent high. A reading of −40 (raw K = 10) means the close is near the bottom. A reading near 0 means price sits at mid-range.
Imagine a ruler showing how far the last price is from the recent low versus the recent high. At +50 (top) the market closed at its highest in 14 bars; at −50 (bottom) at its lowest; at 0 it closed exactly in the middle.
Janira computes Stochastic %K (period 14) 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.
