preference/option in settings "Reset Chart on Start Charting"

It might be good to introduce a preference "Reset Chart on Start Charting" so that the Start Charting "Chart" is always clean. To deal with people who don't enable this feature, your "Start Charting" button should initiate a function that clears all trade plan triggers (left pane) and all chart objects labelled "VEMA-Trigger*" as a minimum, or have this as a second option in the preferences area.
