Automated Support & Resistance Zones for Trading Bots

Support and resistance are where most discretionary trades begin — and where most automation attempts stall, because "the level" was always drawn by hand. The Support/Resistance Zones indicator solves that: it derives zones automatically from swing pivots and widens them by a multiple of ATR, so your bot sees the same areas a chart-reader would.

How It Works

Two inputs shape the zones (defaults: lookback 5, zone ATR multiplier 0.5):

• Lookback controls which swing pivots qualify — larger values keep only significant swings.
• Zone ATR Mult turns each pivot into a zone rather than a line, because markets respect areas, not exact prices.

The indicator outputs the current Zone High and Zone Low boundaries, plus Zone Break Up and Zone Break Down events when price escapes.

How to Trade It

1. Zone bounce (mean reversion). Price enters the lower zone and a momentum trigger like RSI turns up → long back toward the middle of the range.

2. Zone break (breakout). The Zone Break Up event fires → the market has cleared observed resistance; enter with the break, stop back inside the zone.

3. Confluence filter. Only take your existing strategy's longs when price is above the zone — i.e., not walking straight into resistance.

Building It in Setup.Cash

Add Support/Resistance Zones in the strategy builder and use the break events or zone boundaries in your conditions. It pairs naturally with Pivot Points (projected levels vs observed ones) and the Swing High/Low Detector it is built upon. The extended library adds Smart Money Concepts and ZigZag for deeper structure work.

Tuning

• Lookback 5 / Mult 0.5: balanced defaults.
• Bigger lookback: fewer, more respected zones (swing trading).
• Bigger ATR mult: wider zones — fewer false breaks, later entries.

Zones give your bot a map; your entry logic supplies the timing. Backtest bounce and break variants separately — they thrive in opposite regimes.
