Here is another ChartAffair RV Tool update. I fixed a bug similar to the previous one. When building straddle RV chart I noticed there are some artifacts in the end of the chart.

However, previous stock RV data can occupy larger range, so some values remain from previous RV chart and that messes up things.
To fix this I added the following line in DisplayFrontendData() in straddle and calendar code (shown in bold):
