Option screener
An option screener is a tool that evaluates options based on criteria and generates a list of potential trading ideas. Most people who trade options are technical traders. It essentially means they look for patterns in charts. Also they use statistical correlations and deviations and give them Greek names like alpha beta theta gamma.
Few professional money managers use technical analysis and these tools are typically used by individual traders. Its counterpart, fundamental analysis, similarly uses some math to generate ratios, but the inputs and outputs are much more tangible (e.g. income, revenue, assets).
==Overview==
Options, particularly exchange-traded options, are highly volatile securities whose market prices can change rapidly. In addition, the number of options in a market can be large. For instance, as of December 2013, there were over 550,000 individual equity option contracts, written on nearly 6,100 underlying stocks and exchange-traded funds (ETFs), listed on the various U.S. options exchanges. Each contract is typically listed on multiple exchanges, resulting in millions of separate option prices that all change in real-time.
