Delta Streak — Delta, in its own panel below the chart.
What Delta Streak measures
Each bar's delta is reduced to its sign, and the counter either continues or restarts. A bar whose delta is exactly zero prints 0 and ends the run: it neither extends nor reverses the pressure, and the next signed bar starts again at +1 or −1. Because zero is a defined outcome rather than an absence, every bar carries a value and the histogram has no holes. The count runs continuously with no session reset, so a run started before the close can carry into the next session's bars.
The formula, as implemented
This is not how the indicator is usually defined elsewhere — it is what the shipped code computes, documented next to the implementation:
Compte SIGNÉ de barres consécutives de même signe de delta : +1, +2, … tant que delta > 0 ; −1, −2, … tant que delta < 0. Delta = 0 → 0 : une barre neutre CASSE la série (choix documenté — elle ne prolonge ni ne retourne la pression, la prochaine barre signée repart de ±1). Chaque barre a une valeur définie (0 compris) → l'histogramme est plein. Continu — pas de reset session.
How to read it
- A growing magnitude means the same side kept winning bar after bar, whatever each bar's delta was worth.
- A jump from +n to −1 marks the first bar of opposite-sign delta, with no intermediate state unless a bar closed at exactly zero delta.
- A long run alongside little price movement is worth checking on the footprint itself, since one-sided aggression that fails to move price is the shape absorption takes; confirm it on the bars rather than on the count.
- One zero-delta bar resets the counter, so two runs of four separated by a zero bar are not the same thing as one run of eight.
- Compare a run against the usual run lengths for that instrument and bar type instead of applying a fixed threshold.
Parameters and defaults
Smoothing defaults to 1, which keeps the exact integer count; any higher value, up to 200, averages the count across bars and turns the histogram into a trend of run length rather than the run itself. Positive and negative colors default to #26a69a and #ef5350, keeping the two directions separable at a glance.
| Parameter | Type | Default | Range |
|---|---|---|---|
| Smoothing | number | 1 | 1 – 200 |
What it does not show
A bar with a delta of one contract and a bar with a very large delta count the same, so length says nothing about intensity; read the delta itself beside it when that matters. Results depend heavily on how bars are built, since tick, volume and range bars produce run distributions that cannot be compared with those of time bars. On thin instruments, bars closing at exactly zero delta are frequent and fragment otherwise coherent runs. Like every delta-derived series it needs the aggressor side to be available and correct in the underlying data.

Frequently asked questions
- What does a delta streak of +5 mean?
- The last five consecutive bars each closed with positive delta, the current bar included. Nothing is said about the volume involved in any of them: five small positive bars and five very large ones both read +5. The count measures persistence of direction, not force.
- What breaks a delta streak?
- A bar whose delta is exactly zero. It prints 0, ends the current run, and the next signed bar starts over at +1 or −1. The choice is deliberate, a balanced bar neither continuing nor reversing the previous pressure, and it matters most on thin instruments and very short bar periods, where zero-delta bars are common.
- Is a long run of same-signed delta bars a trade signal?
- No. It records that one side kept being the aggressor over consecutive bars, and says nothing about what follows. The same length means different things depending on the instrument, the bar type and where price sits. Use it as a description of current pressure next to price structure and the footprint, not as an entry rule.
