Climax bars Indicator: Formula, Settings and How to Read It
Climax Bars marks bars where effort and result were both statistically extreme: volume and price range each exceeded their recent average by a set number of standard deviations. A dot is drawn at the high of every bar that passes both tests.

Climax bars ships with the Senzoukria desktop app, in the Tape & flow group of the indicator catalogue. It is drawn on the price chart.
What Climax bars measures
For each bar, the mean and the population standard deviation are computed over the N bars strictly before it, so the bar under test never contributes to its own baseline. Volume must exceed its mean plus k standard deviations, and the range — high minus low, in price units — must exceed its own mean plus k standard deviations. Both comparisons are strict, which means that even on a perfectly flat baseline, where the deviation is zero, a bar still has to beat the average to qualify. The defaults are 20 bars and 2 standard deviations. No marker is drawn during the warm-up period, before N complete bars exist.
The formula, as implemented
This is not a description of how the indicator is usually defined elsewhere — it is what the shipped code computes, documented next to the implementation:
Barres CLIMAX — effort ET résultat extrêmes simultanés : vol[i] > μ_vol + k·σ_vol ET range[i] > μ_range + k·σ_range range = high − low (unités de PRIX : le z-test est invariant d'échelle, aucun tick size requis). μ/σ (population, ÷N) sur les N barres STRICTEMENT précédentes (convention de famille, cf. en-tête) ; inégalités STRICTES — baseline constante (σ = 0) : seul un vrai dépassement de la moyenne déclenche. Défauts : N=20, k=2 (l'extrême statistique classique). Marqueur : dot au HIGH de la barre. Warm-up → aucun marqueur.
How to read it
- A climax dot says the bar was unusual in both effort and travel relative to its own recent history. It does not say the move is over.
- Location carries most of the meaning: a climax bar after an extended run is read differently from one at the start of a move or on a scheduled news release.
- Watch the bars that follow. Failure to extend beyond a climax bar's extreme is the observation traders usually act on, not the dot itself.
- Clusters of climax bars indicate a change of volatility regime, after which the baseline itself shifts and markers become rarer.
- Because the test is relative, a quiet instrument can produce markers on bars that are small in absolute terms.
Parameters and defaults
Period defaults to 20 bars and sets how far back the baseline reaches: a short period adapts fast and flags more bars, a long one holds a stable reference and flags fewer. Sigma defaults to 2, the conventional threshold for a statistical outlier; raising it toward 3 leaves only the rarest bars, lowering it toward 1 produces markers on ordinary activity. Because the range is measured in price units, the test is scale-invariant and needs no tick size.
| Parameter | Type | Default | Range |
|---|---|---|---|
| Period | number | 20 | 2 – 500 |
| Threshold (σ) | number | 2 | 0.5 – 5 |
What it does not show
The marker is a statistical statement about one bar against its own recent past, not a turning point and not a signal. It appears only once the bar has closed, so the extreme price it marks has already traded. The baseline is sensitive to what precedes it: after a quiet stretch, moderate bars qualify, and after a volatile stretch, genuinely large bars do not. Over the first N bars of a chart no marker can be produced at all, since a partial window would misrepresent the period it claims to cover.
Using it in Senzoukria
Add it from the Indicators panel of any footprint chart or candle chart. It runs on futures data from Rithmic or Databento and on crypto pairs from Binance and Bybit, on the same engine — the calculation does not change with the venue, only the data feeding it does. Market data subscriptions are billed by the provider, separately from the app.

Frequently asked questions
- What is a climax bar in orderflow analysis?
- A climax bar is one where both the traded volume and the price range are unusually large compared with recent bars. The combination matters: heavy volume with a small range suggests absorption, while a wide range on light volume suggests thin trade. A climax bar is the case where effort and movement are extreme together.
- How many bars are needed before climax markers appear?
- At least as many as the period setting, which defaults to 20. The baseline mean and standard deviation come only from bars strictly before the one being tested, so no marker can be drawn until a full window exists. Partial statistics are not used, since they would misstate the period.
- How do I make climax detection less sensitive?
- Raise the sigma threshold, which defaults to 2 standard deviations; moving it to 2.5 or 3 restricts markers to progressively rarer bars. Lengthening the period has a related effect, since a longer baseline is less disturbed by a recent quiet or volatile stretch.
