I frequently trade options on Tesla, which has an expansive and very active options chain, with large numbers of puts and calls available to be bought or sold at a wide range of prices expiring weekly.
By comparison, other stocks have smaller numbers of puts and calls available within a more limited price range and often with expiration date options being no more than one per month. As in, an option for December 2017 instead of one for each week of December.
Although I've tried google searches akin to "stocks with high volatility" and "stocks with large options chains," I haven't found anything else like Tesla.
How can I find other such stocks that are good for short-term options trading? It's not something I know how to research. I don't know what to look for.
