@Alan That heatmap on the earningschart page is kind of a relict. It was there before the whole backtest page. You can access calendars on the backtest page. Let me know if you have more questions.
With great sadness, we inform you of the death of our long time contributor Michael C. Thomsett.
Michael was a widely published author with over 80 business and investing books, including the best-selling Getting Started in Options.
Michael wrote about 70 articles for the SteadyOptions blog.
He will be missed.
