Delta divergence

Delta divergence occurs when price moves in one direction while delta moves in the other: a higher close on negative delta, or a lower close on positive delta. It flags a move that aggressive flow did not pay for, which often means absorption by resting orders.

Two kinds of divergence

The bar-to-bar version compares one bar with the previous one. If the close is higher and the bar delta is negative, sellers were aggressive yet price rose. If the close is lower and the delta is positive, buyers were aggressive yet price fell. Each case is a single event.

The cumulative version compares the change in CVD with the change in price over a window of bars. Price at a higher level with a lower cumulative delta over the window means the leg was less aggressively bought than the previous one. This filters out the noise of a single auction.

  • Bar-to-bar: close[i] > close[i−1] and delta[i] < 0 → bearish marker; mirror for bullish.
  • Cumulative: ΔCVD < 0 and Δprice > 0 over N bars → bearish; mirror for bullish.
  • Both use strict inequalities. An unchanged close or a zero delta is not a divergence.

Why the marker follows the flow

  • The marker takes the sign of the delta, against the price. Net buying while price falls means someone is accumulating against the drop, so the marker is bullish and drawn at the bar low.
  • Net selling while price rises means the rise is not paid for by aggressors; the marker is bearish and sits at the bar high.
  • Using the same convention for both the bar and the CVD version keeps the two readable side by side.

In Senzoukria

Delta Divergence is an overlay indicator that draws arrows on the price chart using the bar-to-bar rule above. The first bar of a series gets no marker because there is no previous bar to compare with. CVD Divergence uses the windowed rule on the session cumulative delta; both bars of the window must belong to the same session, and no marker is drawn during warm-up or across a reset.

There is also a continuous score version, Price/Delta Divergence, drawn in a pane rather than as events: it compares the sign of the change in close with the sign of the change in delta over N bars and returns a value between −2 and +2. The event markers and the score answer different questions and are deliberately separate.

Confirming and avoiding traps

  • Open the footprint at the divergent bar. Absorption shows as heavy bid volume at the top of an up bar, or heavy ask volume at the bottom of a down bar.
  • Divergence during a strong trend often resolves by continuation. The absorbing side can be exiting, not reversing.
  • A divergence on a bar with tiny volume is noise. Check the size of the delta, not only its sign.
  • Missing delta on imported bars produces no marker, not a bullish or bearish one.

Frequently asked questions

Is delta divergence a reversal signal?
It is a mismatch between price and aggression, which is one condition often seen before reversals. It also appears during pauses in trends and before continuation. Treat it as a reason to look at the footprint and the resting liquidity at that price, not as an instruction.
Which is more reliable, bar delta divergence or CVD divergence?
They measure different things. The bar version catches single-auction events and is noisier; the CVD version compares the accumulation of one leg with the price displacement and is slower. One way to combine them is to frame a level with the CVD version and to time the reaction at that level with the bar version.
