# Supply and Demand Daily Supply and Demand Daily is an indicator on [Vela](https://vela.luxalgo.com/chart), our next-generation charting platform, written in Pine Script®. Builds each day's supply and demand zones automatically from the prior session and plots them as support and resistance on any chart. Zone width tells its own story (wide areas kept price away, thin ones saw constant testing), and the running history doubles as a trend map. A hands-off zone tool made for day traders. - Indicator in the LuxAlgo Library, by LuxAlgo, published Jun 22, 2023. - Access: free. - Concepts: [Supply & Demand Zones](https://www.luxalgo.com/library/concept/supply-and-demand-zones/) (primary), [Volume Profile](https://www.luxalgo.com/library/concept/volume-profile/) - Open on Vela: https://vela.luxalgo.com/chart?pineScriptCodeId=cmpwn65ep008ovhsgsaiheb3v - Page: https://www.luxalgo.com/library/indicator/supply-and-demand-daily/ **Supply and Demand Daily** delivers a fresh pair of [supply and demand areas](https://www.luxalgo.com/library/concept/supply-and-demand-zones/) every session, each built from the previous day's trading and projected onto the current chart. There is nothing to anchor and nothing to redraw: the tool applies the volume logic of the visible-range original on a fixed daily cadence, leaving a running trail of zones that records where buyers and sellers have been defending price. ## How to Trade the Supply and Demand Daily? - **Supply overhead, demand underfoot**: upper areas mark where sellers are likely to dominate and price may stall or reverse; lower areas mark buyer territory where an upward bounce becomes more plausible. - **Read the width**: wide zones are ones price rarely revisited (a sign of supply or demand strong enough to deter a return), while thin zones show levels the market keeps testing. - **Zones as trend filter**: a drop below the prior day's demand zone leans bearish, and a climb above its supply zone leans bullish. - **Watch pullbacks and throwbacks**: price returning toward a freshly broken zone offers a second look at the level before the move resumes. Because each zone is stamped from completed daily data, the historical series shows how these areas migrate as the market trends or ranges. ## Supply and Demand Daily Settings - **Threshold %**: percentage of total volume used to set the areas. Higher thresholds yield broader zones and a wider band of potential support and resistance. - **Resolution**: the number of bins used to determine each area; more bins mean finer delineation. - **Intra-bar TF**: the timeframe the indicator samples for intra-bar data. ## Frequently Asked Questions ### How does this compare with the anchored version? [Supply and Demand Anchored](https://www.luxalgo.com/library/indicator/supply-and-demand-anchored/) asks you to place the calculation window yourself, which suits event-by-event analysis. The daily build automates that decision, rebuilding zones from each completed session so the chart always opens on current levels. ### What does an unusually wide zone tell me? Width reflects how price interacted with the area: wider zones typically mean price seldom returned, pointing to strong supply or demand. Thinner zones mark prices the market tested repeatedly, highlighting ongoing interest. ### How do I get Supply and Demand Daily? It's free in the LuxAlgo Library.
