The Volume at Price (VAP) indicator allows you to see a simple graphic of the closing prices that have occurred the most within defined price zones. The position of the VAP, and the number and size of price buckets can be adjusted, along with lookback period (eg 52 weeks, bars on screen) over which the data is calculated.
