Implied Volatility Rank

A broker I use calculates Implied Volatility Rank. I would like to use this in some explores I run looking for candidates.. I know nothing about coding and was hoping perhaps someone could give me an idea if this is an easy task, translating this to AFL code.

100 x (the current IV level - the 52 week IV low) / (the 52 week IV high - 52 week IV low) = IV Rank

many thanks-

Implied volatility is derived from option prices, not historical prices of the underlying instrument. Therefore, you would either need a source of pre-calculated implied volatility data (I don't know of any for retail traders) or if you wanted to calculate it yourself you would need a full complement of options data for every symbol on which you wanted to calculate IV Rank.

If you're using thinkorswim (one broker who provides IV Rank) then it would probably be simpler to create your initial scan using their tools, and then possibly import the resulting list into AmiBroker for further analysis.

Also, you may way to verify your license so that you can continue to post on the forum: License Verified badge
