Index workflow

Heatseeker for SPX: a pre-trade map for nodes, confluence, and invalidation

A practical SPX Heatseeker workflow using GEX, VEX, SPY and QQQ confluence, King Nodes, Gatekeepers, ranges, VIX context, and map reshuffles.

Independent verdictSPX is where Heatseeker’s map-first workflow is easiest to understand, but the strongest read compares SPX with SPY and QQQ instead of trusting one index in isolation.

A pre-trade workflow designed to slow the decision before a fast contract creates urgency.

Decision rule: If the location has passed or invalidation is unclear, the workflow should produce “no trade.”

01

Build the map before the move

Begin with the largest nearby SPX nodes and mark the King and Gatekeeper zones on your chart. Identify range extremes and the midpoint. A midpoint with poor risk-to-reward is often where patience matters most.

Switch between GEX and VEX to see whether the structures reinforce one another. Then inspect SPY and QQQ for comparable floors, ceilings, or disagreement.

02

The SPX confluence checklist

Before taking an index trade, make the thesis survive several independent questions.

Is price at an edge or trapped in the middle?Do SPX, SPY, and QQQ support the same direction?Does VIX context help or fight the idea?Is the map stable or actively reshuffling?What exact behaviour invalidates the trade?
03

Why 0DTE makes discipline more important

Short-dated contracts magnify execution mistakes. A correct directional idea entered late can still lose through premium decay, volatility change, or a small reversal. Heatseeker can improve location, but it cannot repair oversizing or a missing exit plan.

Use the map to reduce forced trades. The highest-value output may be deciding that price already completed the easy part of the move.

Worked example

Build the SPX plan before the opening impulse

SPX opens between two important nodes with 0DTE contracts moving quickly.

Nearby levels define decision areas.SPY, QQQ, VIX, and chart structure provide confluence.Fast contracts make late entries and loose invalidation expensive.
Decision
Wait for a defined interaction, size from the invalidation, and skip the trade if the clean location has passed.
Invalidation
Price accepts through the level, the map reshuffles, or cross-index evidence reverses.

What this teaches: The map is most valuable before urgency changes the trade.

Frequently asked

Heatseeker SPX questions

Should SPX, SPY, and QQQ always agree?

Perfect agreement is not guaranteed, but Skylit guidance treats cross-index agreement as stronger confluence and disagreement as a reason to reduce confidence.

Is Heatseeker designed for SPX?

Skylit identifies SPX, SPY, QQQ, /ES, and /NQ among the high-liquidity products where Heatseeker is especially useful.
