@Djtux Can you double check your data source for ROKU IV on T-0 which was yesterday (May 1)
I had a long straddle open and was watching IV for the ATM strikes. I never got above 300 and actually fell down to around 275 as shown in Think or Swim

in VolHQ it shows that straddle IV went up to 530 which is not what I saw in real-time. I have noticed this a few times and its dangerous because the IV estimates seemed to be always inflated for many stocks. Thank you.
