Volume lock when dragging orders on the chart. Currently, when dragging orders on the chart, Price and Quantity are blocked (their value does not change), and the Volume value changes. However, most often, especially on the spot market, orders are for a specific value (Volume), usually expressed in USDT. When such an order is moved on the chart, its value increases or decreases, which sometimes leads to a situation in which its value is too high or too low relative to the trader's plan. This often leads to a situation where an error occurs because the balance is too small to complete the order, so the order is removed from the chart and has to be added manually again. I suggest adding the option to lock it in the interface by, for example, clicking the padlock icon next to Volume, which would lock the value. Alternatively, such Volume blocking could be enabled in the application settings.
