The Volume Profile (VP) is a 2nd dimensional horizontal view of the market price and volume difference at each tick or set tick range.
VP calculates and displays the volume difference for each tick range. Meaning, it takes how many contracts were bought at the ask, versus sold at the bid price and totals the differences plus or negative.
It displays the differences in cyan for positive and red for negative colors and plots the numeral text differences for each lot size.
The Range Tick Size measures the volume difference as a whole rather than just 1 tick. It combines the calculation into into set tick ranges. 4 ticks would be 1 full point in the ES Sp500 for example. Much more effective is seeing true momentum.
You can set up to 3 lot sizes. We defaulted 1, 25 and 100 lots. The larger the lot size, the darker the color.
When set to 25, you will only profile 25 lots and more. The 100 lots is the same; profile 100 lots of more. You can see the small to larger traders all on the same line now with different faded colors.
