Simple Volume Profile with a Point of Control (POC). The script does the following:
Accumulates volume in user-defined “bins” (price buckets) for a session. Resets the volume accumulation each new “session”: On a Daily chart, it considers weekly sessions (resets each Monday). On a 4H chart, it considers daily sessions (resets at the start of each trading day). Finds the Point of Control (the price bin with the highest accumulated volume). Plots the histogram and the POC line on the chart.
