Hot Zone Radar
By LuxAlgoFeb 19, 2026
Hot Zone Radar is an indicator on Vela, our next-generation charting platform, written in Pine Script®.
Hot Zone Radar turns raw volume into a thermal map of market liquidity, pairing a rolling Radar Dashboard heatmap with gradient support and resistance zones projected directly onto price. Cell colors run from deep blue and cyan (cold, thin liquidity) to bright red (hot, heavy liquidity), each graded against the busiest price level in the current volume profile, while a dotted price trace shows where the market sits within that structure.
How to Trade the Hot Zone Radar?
- HOT status: price is oscillating inside a major liquidity hub. Range-bound conditions are likely, favoring mean-reversion tactics.
- COLD status: price is moving through a low-volume vacuum, where momentum breakouts can accelerate with little in the way.
- WARM status: price is trending toward a high-volume cluster that can act as a magnet, useful for target setting.
- Gradient S/R boxes: the strongest liquidity clusters projected onto the chart; their gradient shifts when price enters, flagging active interaction where rejection or compression often develops.
Because the dashboard scrolls through time, it shows not just where volume sits but how long it has persisted: long-lived hot zones read as structural levels, while fading nodes warn the map is being redrawn.
Hot Zone Radar Settings
- Profile Lookback: how many bars feed the volume distribution.
- Resolution (Heatmap Grid): vertical bins and horizontal steps, more detail at a higher processing cost.
- Diffusion Blur and Intensity Gamma: smoothing strength and color sensitivity; lower gamma makes hot zones appear more readily.
- Show Gradient S/R Zones, S/R Sensitivity %, Gradient Steps: toggle the projected boxes, set the volume threshold a zone must clear, and control the layered glow.
- Position and Overall Panel Size: dashboard placement and scale.
