Min Delta Indicator: Formula, Settings and How to Read It
Min Delta charts the lowest value the running delta reached inside each bar, as a histogram. It marks the deepest point of selling aggression during the bar, independently of where delta finished.

Min Delta 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 Min Delta measures
The series reads the optional intrabar low-delta field written by the backend when the tick source provides it, and prints nothing when the field is missing or not finite. It is defined separately from Max Delta so that either extreme can be enabled and coloured on its own, which is useful when only one side of the auction is under study. A positive reading, shown in neutral grey, means the running delta never dipped below zero during the bar: there was no moment at which aggressive sellers were collectively ahead.
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:
Delta minimum INTRA-barre : lit `deltaLow` (champ OPTIONNEL, mêmes règles que `max-delta` — barre sans le champ ou non fini → pas de point, jamais de valeur inventée). Def séparée de `max-delta` : chaque extrême s'active et se colore indépendamment.
How to read it
- A deep negative column paired with a closing delta near zero describes selling that entered the bar and was met before the close.
- A grey, positive column means net aggression stayed on the buy side at every point of the bar, a stronger statement than a positive closing delta alone.
- When the minimum is deep but the bar's price low barely extends, the selling was met by resting bids rather than moving price.
- A run of deep minima without correspondingly lower closes describes repeated selling attempts that price is not following.
- Read the column against the bar's volume: a deep minimum on a thin bar can come from very few contracts.
Parameters and defaults
Colours are inverted relative to Max Delta: positive readings default to grey (#9e9e9e) and negative ones to red (#ef5350), so the eye is drawn to the selling extreme and not to the benign case. Smoothing defaults to 1 and can go to 200, but averaging a trough across bars raises it artificially and hides the single-bar events the indicator exists to surface.
| Parameter | Type | Default | Range |
|---|---|---|---|
| Smoothing | number | 1 | 1 – 200 |
What it does not show
A deep minimum can be produced by one large sell order or by a long stream of small ones, and this series cannot tell the two apart. It also reports nothing about the resting bids that absorbed the selling, which is heatmap and DOM territory rather than delta territory. The value depends on tick-level data with an aggressor side, so bars built from aggregated sources are simply skipped, and the scale changes with bar type and volume, making cross-timeframe comparison unreliable.
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 does min delta show on a footprint bar?
- It shows how far the bar's running delta fell at its worst point for buyers, wherever inside the bar that happened. Because the value is taken from the tick sequence and not from the finished level table, it survives even when the bar closes with a positive delta. That makes it a record of selling pressure the closing figure alone would hide.
- What is the difference between min delta and bar delta?
- Bar delta is the final value at the close of the bar, while min delta is the most negative value the same running total touched on the way there. A bar can close at +120 after having been at −600, in which case bar delta reports the outcome and min delta reports the fight. Reading them together shows whether the close was reached smoothly or against resistance.
- Does a deep min delta mean sellers are in control?
- It means sellers pressed hard at some point inside the bar, nothing more. If price held while delta went deeply negative, the reading describes selling that was met by resting buy orders, which is close to the opposite conclusion. The indicator records aggression, and control is only visible when that aggression is compared with what price and the book actually did.
