Naked POC Indicator: Formula, Settings and How to Read It

Naked POC draws the point of control of each past session that price has not traded back through since. A level stays on the chart only while no later bar's range has covered it, and disappears the moment one does.

Naked POC ships with the Senzoukria desktop app, in the Structure & sessions group of the indicator catalogue. It is drawn on the price chart.

What Naked POC measures

The touch test is inclusive and has no tolerance: any bar after that session whose low is at or below the POC and whose high is at or above it removes the level permanently. Each session's point of control comes from its aggregated volume profile — the price level that traded the most volume during that session — and when two levels tie, the lower price is used, following the Sierra convention adopted across this platform. Every surviving level is drawn from the start of the session following it through to the right edge of the chart. When the instrument's tick size is unknown, prices are quantised at 1e-6 so that no raw floating-point value is used as a profile key; the arithmetic stays exact either way.

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:

Naked POC (nPOC) : POC de chaque session PASSÉE que le prix n'a JAMAIS retouché depuis — aucune barre postérieure à la session avec low ≤ POC ≤ high (test de touche INCLUSIF, sans tolérance). Un niveau par nPOC encore vierge, tracé du début de la session suivante au bord droit (to: null — un nPOC touché n'est simplement pas émis). POC par session : profil agrégé (`addBarToProfile`), égalité → prix le plus BAS (Sierra, choix du repo). Tick inconnu → quantification 1e-6 (canon) : le calcul reste exact, aucune clé f64 brute.

How to read it

  • An untouched POC marks a price where a past session concentrated its volume and where price has not returned since.
  • Age is a description, not a ranking: a level unvisited for two weeks has been unvisited longer than yesterday's, which does not make it stronger.
  • Several naked POCs stacked close together mark a band where consecutive sessions concentrated their volume before leaving it behind.
  • The level vanishing is itself the event — once price trades through it, it is no longer a naked POC and is not drawn.
  • Everything here depends on the history you have loaded: a level can only look untouched relative to the bars in the chart, so a shallow history will show levels that deeper history would have cleared.

What it does not show

The indicator identifies a price with a history and stops there; what happens if price reaches it is not part of the calculation. The output depends entirely on loaded history depth and on the session anchor being appropriate for the instrument — on a continuously traded crypto series that anchor is a convention. A session with very thin volume still produces a point of control, and that POC may reflect noise rather than genuine acceptance. The profile needs volume distributed by price, so a feed that does not supply it weakens the POC itself. And since the touch test is inclusive with no tolerance, a single one-tick wick through the level removes it for good.

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 naked POC?
A naked POC, or untested point of control, is the highest-volume price level of a past session that price has not traded back through since that session ended. It is used as a reference price because it marks where an earlier auction concentrated activity and then left without returning. Once price trades at that level again, it is no longer naked.
Why did a naked POC disappear from my chart?
Because price traded through it. The test is inclusive and has no tolerance: any bar after that session whose high-to-low range covers the POC clears the level, including a bar that only wicked through it for a single tick. The level is then no longer drawn, since it has been tested.
Which price is chosen when two levels have the same volume?
The lower of the two prices is used. That follows the Sierra convention, which this platform applies consistently wherever a point of control tie has to be broken. It matters mostly on quiet sessions and coarse tick grids, where exact volume ties between adjacent price levels are more common.
