## Use case: option strategy based on IV to SV ratio

### Overview

In modern financial markets, it is becoming increasingly difficult to keep up with the flow of information. The right set of tools is often the key to understanding what’s important and what’s not. This is especially true in the case of option markets where the number of outstanding contracts is enormous.

Here we examine one possible scenario of options analysis using dxFeed Options Scanner.

The ratio of implied (IV) and statistical (SV) volatility of the underlying security measures the relation between the theoretical and the market price of the option. A high ratio indicates the option is overpriced (e.g, investors treat the asset as a hedge) and vice versa (e.g., insufficient liquidity).

If the ratio is sufficiently high, (e.g., greater than 1.3), it is a possible sign that option-selling strategies are viable. There’s a range of applicable approaches, such as selling the naked or covered option, or shorting the straddle (a combination of a call and put), to name a few. While the choice of a particular strategy is up to each trader’s style and risk preference, dxFeed Options Scanner allows them to quickly highlight cases for further analysis. We would also like to narrow our search down to the options near the money, with a strike price between 0.95 and 1.05 of the latest available price of the underlying security.

### Using dxFeed Options Scanner

Choose the options data points to receive:

price

symbol

Select the data points that will be used to find options you are interested in:

underlying.atmIv60Day = the implied volatility of an ATM option with a residual maturity of 60 days

underlying.statVol2Month = the annualized historical standard deviation of logarithmic returns, calculated based on 2 calendar months

strikeMoneyness = the ratio between the options strike and the latest available price of its underlying security

dayVolume = current day volume of the instrument

callput, Call $\left(C\right)$ or Put $\left(P\right)$

To get the ratio between ATM IV and SV, create a new mathematical expression:

ratio: underlying.atmIv60Day / underlying.statVol2Month

Add filters to the desired attributes. In this case, we are interested in near the money call options with sufficient trading volume and a high IV to SV ratio:

a ratio greater than 1.3

strikeMoneyness between 0.95 and 1.05

dayVolume greater than 1000

callput equals $C$ (call)

The results will be returned with the data for selected data points. For example, the result might be presented as follows:
