How it works: this option gives you an ability to adjust the number of decimal places in volume amounts. Default value = 4, minimum = 0, maximum = 8.
Example: volume 0.11223344 with setting value = 4 will be displayed as 0.1122. Reducing the number of decimal places facilitates the perception of values. The setting does not apply on volumes (orders, positions, trades by price) because accuracy is important in its case.
