Searching for Options

Hi Guys,
What is the best way to search for High IV options using thinkorswim? I tried different ways. In the 1st screenshot of TOS, does not give me filter to add IV.

In the 2nd screenshot of TOS, nothing comes up with the filters applied.

Because the little white button on the right towards the bottom is set to 1m (1minute candles) click on it to change it to 1d (1day). Might as well change you max volume slider to as high as it will go.

Intersect with "all stocks", that ok? Or would you recommend something else like tasty-trade or S&P 500?
-What do you think about the Days to Exp 30-45 ?
-The volume is Stock Volume, not options volume. That ok ?
-If I was to add Delta, what value do YOU put in ? I was told -1 to +1
-Any other helpful filter you can suggest ?
Thanks

The way you have it is fine....maybe 30-55 days would be good. I would only add more filters if I was getting too many results. Your probably not going to get too many on the scan.

Another interesting scan is under the scan tab click on "Spread Hacker" . I usually just scan for a price range and days to expiration 30-55. Then you can sort by name or volatility or probability or whatever. It's kinda cool for ideas.
