Session Volume Profile HD is a trading indicator that displays a horizontal volume profile for each trading session directly on the price chart. It visualizes how trading volume is distributed across price levels within defined sessions, helping traders identify high-activity zones, fair value areas, and key support and resistance levels based on volume behavior.

The indicator processes volume data at each new bar close by scanning bars within the selected number of sessions. It distributes tick volume across the price range of each bar, separating volume into buy-side (bullish bars) and sell-side (bearish bars) components using bar open/close direction as a proxy. The volume profile is rendered as a layered horizontal histogram anchored to the session's time boundary.

Visual elements include teal buy bars, red sell bars, a yellow Point of Control (POC) line marking the highest volume price level, a blue overlay representing the value area containing a configurable percentage (default 70%) of total session volume, and white dotted lines marking session high and low prices.

The indicator redraws only once per new bar to ensure stable rendering without flickering. Buy/sell volume is approximated using bar direction due to platform data limitations, with bullish bars weighted 65% buy / 35% sell and bearish bars the reverse. This indicator supports markets including Forex, indices, commodities, stocks, and cryptocurrencies.
