when I make new chart (menu File/New/Chart), in the field "Price based on" I can select Ask, Bid or Last (picture 1).
If I select "Ask" in this field, then what means the Volume on the chart (picture 2) ?
Is this the [total volume of all orders for sell] ?
Or it is the [volume of the best orders for sell (orders with the lowest price)] ?
Or something else ?
Thanks
