Supply&Demand is a trading indicator that automatically identifies and plots key supply (resistance) and demand (support) zones on price charts in real time. It detects swing highs and lows using configurable lookback and zone-width settings, adapting to any market or timeframe. The indicator highlights “virgin” zones—areas untouched by price—emphasizing potential institutional order levels, with an option to hide touched zones for chart clarity.

It supports multi-timeframe filtering, allowing users to display zones aligned with higher timeframe multiples on lower timeframe charts, facilitating confluence analysis. Zones are non-repainting and non-lagging; once drawn, they remain fixed, ensuring reliable historical analysis. Custom alerts notify users when price enters or breaks these zones, and detailed logs track zone creation and interactions.

The indicator operates by scanning each new bar for pivot highs and lows, constructing rectangular zones extending forward, and filtering overlapping zones to retain the most significant areas. It offers a “virgin-only” mode to focus on fresh institutional levels.

Example strategies include zone rejection, multi-timeframe confluence, and break & retest setups, often combined with RSI or MACD divergence for higher-probability signals. A real-world example on EURUSD H4 demonstrates entry, stop-loss, and take-profit placement based on demand zones and candlestick confirmation.
