Time And Sales Delta

The indicator displays the delta and the cumulative delta based on the "Time & Sales" deals list data.

In addition to the standard timeframes, the indicator displays data regarding the seconds timeframes (S5, S10, S15, S20, S30) to choose from.

Using the rectangle, user can select an arbitrary area in the indicator subwindow to view the ratio of the volumes of deals of buyers and sellers within this area.

For trading symbols that have the tick history without the content of the list of deals, an interpretation algorithm is exist: 

• Each positive Ask tick is interpreted as the unit of volume to buy. 
• Each negative Bid tick is interpreted as the unit of volume to sell. 

This algorithm works in the mode Calculation=Interpretation and is relevant mainly for currency pairs.
