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. 94 contracts (avg 29 vol/day, 94 traded recently)

RYTM averages only 29 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 put: the $120.00 10-16 put last traded $10.75 on 08/13 (now $19.90/$23.80) — try a limit near $19.90.
