Delta Concentration % Indicator: Formula, Settings and How to Read It

Delta Concentration % ships with the Senzoukria desktop app, in the Delta group of the indicator catalogue. It is drawn in its own panel below the chart.

What Delta Concentration % measures

The most imbalanced level is the one with the largest absolute difference between buy and sell volume; it is found among the same usable levels that feed the denominator, so a level discarded for zero quantity or an invalid price disappears from both sides of the ratio and the share stays honest. Because the denominator is a signed sum taken in absolute value at the end, levels pulling in opposite directions cancel each other, and the result can legitimately exceed 100%: a bar with +50 at one level and −45 at another nets to +5 while its largest level is 50, giving 1000%. That behaviour is deliberately not clipped, since capping the value at 100 would erase exactly the case worth seeing. When the bar's summed level delta is zero, no point is plotted, because a division by zero is an absence of reference rather than a reading of 0%.

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:

Concentration du delta — quelle part du déséquilibre de la barre tient à UN seul niveau : value = |delta du niveau le plus déséquilibré| / |Σ delta des niveaux| × 100 Le niveau « le plus déséquilibré » = celui de |buy − sell| maximal. Numérateur ET dénominateur viennent des MÊMES niveaux exploitables (et non de `totalDelta`) : un niveau écarté par le canon (qty = 0, prix non fini) doit disparaître des deux côtés du rapport, sinon la part est fausse. POURQUOI : 100 % = tout le delta de la barre est venu d'un prix unique (un gros ordre ponctuel) ; 20 % = flux réparti sur toute la barre. La lecture change du tout au tout pour un même delta global. Convention : valeur > 100 % LÉGITIME et non bornée — des niveaux de signes opposés s'annulent au dénominateur (ex. +50 et −45 → total +5, max 50 → 1000 %). C'est l'information la plus utile de l'indicateur : borner à 100 l'effacerait. Delta total nul → PAS de point (x/0 n'est pas « 0 % », c'est une absence de référence).

How to read it

• Values near 100% mean essentially one price produced the bar's imbalance. That is consistent with a single large order, though the indicator itself cannot establish who traded.
• Low readings, in the region of 20%, describe flow spread across the range: many levels each contributed a small part of the same net delta.
• Readings far above 100% are informative, not errors. They mark bars where buying at some prices and selling at others largely cancelled, leaving a small net delta over a much larger internal fight.
• The same bar delta can carry very different concentration values, so read the two together. Concentration changes what the delta means; it does not change the delta.
• A sudden jump in concentration on an otherwise ordinary bar points to one price doing the work, which is a reason to look at the footprint of that bar rather than to act on the value.

Parameters and defaults

Colour only affects the plotted line. Smoothing defaults to 1, which leaves the percentage exactly as computed on each bar; any higher value averages it over that many bars, and since this indicator exists to surface the isolated bar where one price did the work, averaging is working against its purpose more than for most series.

What it does not show

The indicator is a ratio, so it is blind to size: a 100% reading on a bar of forty contracts and one on a bar of forty thousand look identical. It identifies the largest imbalance, not who created it, and cannot distinguish one institutional order from several participants happening to trade at the same price. Bars whose level deltas sum to zero produce no point, which leaves gaps in the series on balanced bars. In thin markets, where a bar may only hold a couple of levels, concentration is mechanically high and says little.

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.
