Definition :

VPO is a Volume Price Opportunity. Instead of using bars or candles with an Open, High, Low, and Close price, each “bar” in a Market Profile is represented by horizontal bars against the price It is called Market Profile terminology.
In other words volume-price-opportunity (VPO) profiles are histograms of how many volumes were traded at each price within the span of the profile.
By using a VPO chart, you are able to analyze the amount of trading activity, based on volume, for each price level the market traded at for any given time period. The VPO Profile Chart study allows you to clearly see the areas where the market is trading with the max volumes.

The indicator can help determine Support-Resistance levels.

Tips :

• You can attach more than one indicator to a chart with different settings in these cases :
• If you want multiple sessions on a day,
• If you want both right and left on side histograms on a chart,
• If you want 2 or more histograms overlapping each other.
