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 $110.00 08-21 call last traded $6.75 on 08/07 (now $4.40/$7.30) — try a limit near $5.85. Most tradeable put: the $105.00 03-19 put last traded $16.75 on 06/24 (now $10.60/$14.20) — try a limit near $12.40.
