Tools in the chart are not stable

there is some bugs in the drawing and tools used for chart for example a vertical line that draw on the daily is not present on other timeframes (this bug is not persistent but did happen) the fibo retracement could not be used on the 5 min timeframe (can be used on the timeframes) the scaling of the chart get ruined if i modify the scaling on onetimeframe the others are ruines and there is no auto scale to reset so each time i should do it manually other than this there is problem of loading data that can occur but not persistent hope you can fix all that thanks :)
