I had showed you how to scan for IV Rank using IV Percentile on Thinkorswim platform in the last article. I use the scan to find stocks and ETFs with high IV Rank everyday before market open. I only trade options for stocks and ETFs with high IV Rank, following tastytrade methods.
However, I am not able to tell is the IV Rank for certain stock or ETF trending up or down from the scanning results. It is more useful if we have the visual on the trend of IV Rank in the chart. Tastyworks is not really good for plotting chart as of this time. Luckily I still maintain two platforms and Thinkorswim is just the best way to do that. What I did was to find a IV Rank script and put inside the chart. Here is how I did it.
