I am interested in building an indicator based off a time of sales and tick chart. The basic concept is this: I want an easier way to read the tape and to watch for supply vs demand.

What I want is an indicator that plots a histogram of the difference between the number of contracts at the ask vs the number of contracts at the bid. I want this difference taken from a tick chart of choice.

For example: If the tick chart settings were set to 233 tick chart, the histogram will plot the difference between the number of contracts at the ask minus the number of contracts at the bid off one 233 tick bar.

The parameters for the tick chart settings can be changed to whatever.

If anyone can help me with this it would be appreciated. I have no knowledge of EL or coding. Thanks
