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. 131 contracts (avg 206 vol/day, 129 traded recently)

RGEN averages only 206 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 $115.00 11-20 put last traded $8.50 on 07/21 (now $4.50/$6.60) — try a limit near $5.55.
