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 call: the $105.00 10-16 call last traded $4.47 on 09/10 (now $1.80/$2.70) — try a limit near $2.25. Also watch the $120.00 10-16 call last traded $2.41 on 08/31 (now $0.00/$1.40) — try a limit near $0.70. Most tradeable put: the $100.00 12-17 put last traded $16.60 on 09/01 (now $17.50/$22.50) — try a limit near $17.50.
