Here is more on the web-based tools (pricing below):
Test your strategies before trading them in the market. Tweak your criteria, like delta and days to expiration and hundreds more triggers. The Backtester simulates an option strategy using daily data back to 2007. You can find backtester samples, instructions, videos, and tutorials here.
For example: "I want to buy a SPY 5% out-of-the-money put spread every time MACD and implied volatility contango goes negative," here's how.
Find the options meeting your criteria in real-time. Choose from pre-canned scans with default days to expiration and delta ranges. Make your custom scans and choose from hundreds of criteria.
Examples of possible scans:
Plot hundreds of options related data points historically back to 2007 from the ORATS data API. Also, define a range of an indicator to simulate buying and selling of the stock.
