Free Options Heatmap for Comparing Premium Yields Across Expiries
Hi All,
I've been selling options for a while, and one thing I always found annoying was comparing contracts across expiries. I would end up manually calculating premium yields to figure out which contract was actually providing the best return.
So I built an options heatmap that calculates yield % across all strikes and expiries in one view, making it easier to quickly identify where selling may make the most sense without manually doing the math. It also clearly highlights earnings weeks, since elevated premiums can sometimes reflect higher event risk rather than better opportunities.
The heatmap has 3 modes:
• Premium: quickly identify highest-returning contracts
• Assignment Risk Indicator (ARI): estimates assignment risk by considering remaining extrinsic premium and time to expiry
• Delta: traditional probability view of the contract finishing ITM
Clicking on any contract opens additional details including premium metrics and Greeks. The heatmap updates every 5 minutes and is completely free to use. Would love feedback and ideas on improving it.
