What you see

  • Rows. One per contract. Click any header to sort.
  • Mark. The mid price. A wide bid and ask means an illiquid contract, so treat its greeks with care.
  • OI and volume. Open interest is contracts outstanding. Volume is what traded today.

What to look for

  • Check an aggregate view against the real contracts before you trade it.
  • The expiry carrying the liquidity, which is often not the one you assumed.

Questions

Can I filter the chain by delta?

Yes. Add delta_min= and delta_max= to the command, or use the filters inside the panel.

Where does the data come from?

Crypto chains aggregate the listed options venues. US chains come from the consolidated OPRA feed.
