I would like to be able to set the account history for each chart. When multiple charts are displayed and day trading or sca trading is displayed even on the long term charts such as daily, the candlesticks are not visible. The MA is sometimes not displayed in the middle of a chart due to a bug. The sensitivity of the mouse wheel when expanding and contracting the chart is too high, and turning the wheel just a little too far makes it impossible to stop at the right place.
