Historical option prices for this thinly-traded ticker. Live quotes are wide and stale — use where each contract actually traded plus its 30-day range to place a limit order. 125 contracts (avg 99 vol/day, 125 traded recently)

RYTM averages only 99 option contracts/day, so quotes are thin and bid/ask spreads run wide. Use the last actually-traded price below to set a limit order rather than chasing the displayed ask. Most tradeable call: the $90.00 08-21 call last traded $18.81 on 07/17 (now $18.10/$22.10) — try a limit near $18.81. Also watch the $110.00 09-18 call last traded $10.48 on 08/07 (now $4.30/$7.70) — try a limit near $6.00; the $105.00 08-21 call last traded $10.00 on 08/07 (now $3.40/$6.40) — try a limit near $4.90.
