Reaction Entry Engine
A zone touched ten times isn't support anymore. The edge is in the first reaction.
Most zones get drawn after they already worked. This one grades them before price arrives.
Free & open-source · Works on any market and timeframe · An educational analysis tool, not financial advice.
An open-source supply & demand framework: it builds zones from confirmed pivots, validates them with an impulse filter and a quality grade, then projects a full entry / stop / target the moment price makes its first qualifying touch.
Supply and demand is everywhere — and that's the problem. Most tools paint a box on every pivot and treat the first touch exactly like the tenth, so your chart fills with levels and you're left guessing which one actually matters. A fresh zone backed by a real impulse move behaves nothing like an area that's already been chewed through five times.
Reaction Entry Engine is built around one selective idea: the first qualifying touch. It constructs zones from confirmed pivots (chart and higher-timeframe), filters out weak formations with an impulse check, and scores what's left with a quality model that grades each zone A / B / TRASH based on displacement, reaction and penetration. Only when price makes its first touch into a zone that passes your grade does it project a complete entry, stop and target — with on-chart review panels that show how prior projected setups behaved under your exact settings.
It's a structured decision-support and review framework — open-source, so you can read every rule, and free to add to your charts. Not a black box, not a promise: a sharper way to decide which zones deserve your attention.
- Focus on the first reaction into a zone, not the noisy retests
- Filter out weak pivots with the impulse-strength check
- Let the A / B / TRASH grade rank zones before price gets there
- See entry, stop and target projected automatically on a touch
- Free & open-source — read and verify every rule yourself
Traders who treat the first reaction into a zone as the one that matters
6 components, one output
Pivot-built S&D zones
Supply and demand zones constructed from confirmed pivot highs and lows — as areas, not single lines — on the chart and a higher timeframe.
Impulse validation
Filters out pivots that formed without real directional commitment, using candle range, body and close-location vs ATR (and optional volume).
Quality grading (A / B / TRASH)
Scores each zone on post-formation displacement, reaction size, penetration depth and repeated-touch penalties.
First-touch selection
Acts on the earliest qualifying return into a valid zone instead of reacting to every revisit.
Entry / stop / target projection
Projects entry, SL and TP with lines and boxes, with an RR-based target and configurable stop distance.
Review panels
Performance and daily panels summarise projected trades, win rate, profit factor, R and drawdown under your current settings.
From a blank chart to a read
- Add the indicator to a standard candlestick chart.
- Choose zones from the chart timeframe, a higher timeframe, or both.
- Set touch detection (wick / body / both) and enable the impulse filter to drop weak formations.
- Enable the quality engine and pick your minimum accepted grade.
- Wait for a qualifying first-touch BUY or SELL reaction.
- Use the projected entry / stop / target as an analysis framework, and the review panels to compare settings over time.

An exhausted move plus a rejection candle isn't a guess. It's pressure changing hands.
