Supply Demand Liquidity Confluence (SDLC)
A single lightweight overlay that combines two proven zone concepts into one engine: momentum-based Supply/Demand zones and pivot-based Liquidity (Support/Resistance) zones, with optional multi-timeframe confluence.
What it does
- Supply/Demand zones: flags the origin candle of a strong directional move. A move only qualifies if N consecutive candles push the same direction with an ATR-normalized slope above your angle threshold, so slow grinding trends don't get flagged as impulses.
- Liquidity zones: marks confirmed pivot highs/lows once price has closed on both sides of the swing, then tracks retests, overlap volume, and break confirmation (by close or by wick, your choice).
- HTF confluence: turn on a higher timeframe (e.g. H4 zones on an M15 chart) and the same engine runs a second pass, detected only on HTF bar close (not every tick), with its own zone pool so a strong D1 zone is never evicted to make room for M5 noise. HTF zones get a bolder border and richer fill so they read as the "important" levels at a glance.
- Zone age, break handling, and max active count are all configurable per zone type, and history is backfilled on attach so you see zones immediately, not just going forward.
How to use it
- Start on your trading timeframe with Supply/Demand and Liquidity zones both on. Watch for price reacting at a zone for the first time (label shows "Fresh") versus a zone that's already been retested multiple times, fresh zones tend to react more sharply.
- Enable HTF mode with a timeframe one or two steps above your chart (M15 to H4, H1 to D1, etc). The real edge is confluence: when an LTF zone overlaps an HTF zone, that's the level institutional flow tends to respect, and it's worth more weight than either zone alone.
- Use HTF zones as a bias filter. If price is inside or approaching a higher timeframe demand zone, be cautious about taking LTF supply signals against it, you'd effectively be fading the bigger structure.
- Switch Break Confirmation to "Wick" if you trade fast-moving pairs/indices and want earlier invalidation, or keep "Close" for fewer false breaks on choppy instruments.
- Tighten Minimum Impulse Slope Angle if you're getting too many Supply/Demand zones on noisy symbols, loosen it on trending instruments where you want earlier detection.
- Raise Minimum Retests if you only want to see levels the market has already respected at least once, useful for cleaning up the chart on lower timeframes with a lot of pivot noise.
No repainting logic beyond the normal "zone can still break on a later bar", no external dependencies, no DLLs. Fully configurable colors, labels, and zone lifecycle per zone type.
