MBX covered call FAQ
What does the MBX covered call calculator prefill?
A near-30-delta MBX call (and put, for the cash-secured mode) at the bid/ask midpoint from the delayed Cboe chain, plus MBX's delayed price and the days to that expiration. Every field stays editable.
How is a MBX covered call return calculated?
Premium collected divided by your MBX cost basis gives the return if flat; the capital gain up to the strike plus premium gives the return if called. Both are annualized over the days to expiration for comparison.
Is this live data?
The prefill uses delayed (~15 minute) quotes, labeled with their as-of time. Check live quotes at your broker before trading; this page is educational arithmetic, not a recommendation.
