Have you ever researched options by going to one option chain at a time? Did you find that inefficient and time consuming?
FDscanner started because the site creator wanted to optimize his research for selling put premium, and expand his research across the entire option universe.
We launched with the Options Scanner, and over time added additional features. The Tendies index screens for unusually low priced options with respect to 10 day stock price volatility, while the Skew index finds stocks with high Put/Call price imbalances.
If you made over $100 with this site, consider upgrading to Pro which has all 3702 US stocks with options. The free site contains S&P500 stocks.
MAX Tendies Index
A purpose built screener for weekly options with tight spreads.
We built a custom indicator, NTR, based on past 10 days volatility and used it to set price targets for every stock. Then we rank all options by the number of times it will multibag if that price target is hit. The number of times it’ll multibag is the Tendies Index.
In short, the Tendies index finds options that are underpriced relative to recent price movement, narrowing down millions of options to a hundred. It will then be up to you, the trader, to find and seize profitable trades. The index updates every 15 minutes during trading hours, and does a final update at Friday, 90 minutes after open.
Put/Call Skew Index
What is Skew index
Call Skew index shows the ratio of 10% OTM calls to 10% OTM puts and vice versa for Put Skew index.
The option expiry date used is the next monthly expiry date, it’s always between 30 – 60 DTE.
Find Supply/Demand imbalances
An equally OTM put and call should theoretically be priced the same. Skew index curates a list of stocks with unusual supply/demand imbalance in options for you to research further.
Using the Skew index
- If you’re a contrarian, you yield better risk/reward ratios betting against the skew.
- Put premium sellers benefits from high put skew.
- A basket of put options with high call skew could be a more effective hedge than SPY puts.
