Volumetric Spectrogram [by Oberlunar]

Volumetric Spectrogram [by Oberlunar] is a binned volume “spectrogram” that separates buy/sell pressure above vs below the current price and summarises it with two oscillators. Includes optional multi-feed (broker/exchange) aggregation, delta-based colouring, and a sideways compression marker.

Full Description

Most volume displays are either vertical bars or horizontal profiles that do not clearly tell you how pressure differs above vs below the current price. Volumetric Spectrogram builds a binned volume map over a lookback window and splits activity into two regions: bins above price (overhead pressure) and bins below price (support pressure). It then converts the regional buy/sell imbalance into two oscillators (Upper Oscillator and Lower Oscillator) so you can quickly analyse volumetric synchronisation, divergence, and compression.

For volume multi-source confirmation, the script can aggregate up to five broker/exchange feeds of the same market into a consolidated delta bias. Weighting can be Equal, Last Volume, or Adaptive (volume-weighted with an adaptive Supertrend-aligned penalty when a feed’s delta conflicts with its local regime). A small 3-lane strip displays Equal/Last/Adaptive biases side by side, and optional overlay candles can colour the main chart according to the selected mode.

Finally a Sideways Interceptor highlights low-energy phases using oscillator compression plus a volatility gate and a short entry/exit confirmation, drawing a band during compressed conditions (see the yellow bands).



How to

1. Set Volume Period and Volume Bins to balance stability vs responsiveness.
   
2. In Multi-Broker Volume Configuration, pick up to five broker/exchange symbols for the same market and select Weighting (Equal / Last Volume / Adaptive).
   
3. Enable Color bars and lane for delta visuals, and Overlay candles if you want candle coloring on the main chart.
   
4. Enable Sideways Interceptor to mark compression regimes; increase confirmation bars to reduce flicker.
   

Structural evidence
When pronounced volumetric spikes appear (up or down), the trend often reverses sharply. In the figure, the circles highlight the spikes; once the spike subsides (reversion toward baseline), the oscillator turns bullish. The double confirmation of two consecutive minimum spikes acts as support for a possible ensuing up-move, with fill colours confirming direction.


Sideways evidence and breakout
After the volumetric compression, it is possible to expect a breakout, such as shown in the following figure:

In this case, the bars to trigger the sideways interceptor are fixed to 1.

Neutral band bias
The Neutral band (|bias| ≤) setting acts as a deadband for the consolidated delta bias. It is useful when a market has a persistent underlying bullish or bearish tilt, and you want to reduce low-level “flicker” around the midpoint.

With a small Neutral band (near zero), the bias reacts to most changes in pressure:


With a larger Neutral band, only stronger pressure events are highlighted. In this mode, the three lanes (Equal / Last Volume / Adaptive) also make it easier to see whether there is cross-feed consensus:


Limitations & Risks

Buy/sell volume is approximated from candle direction, not true bid/ask delta. Broker/exchange feeds can differ in pricing and volume reporting, so aggregation should be treated as a consensus view. Sideways detection is heuristic and may not catch every transition.
