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. 103 contracts (avg 257 vol/day, 102 traded recently)

RGEN averages only 257 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 $125.00 08-21 call last traded $23.88 on 07/14 (now $14.50/$18.30) — try a limit near $16.40. Also watch the $145.00 08-21 call last traded $11.60 on 07/17 (now $4.20/$7.70) — try a limit near $5.95. Most tradeable put: the $140.00 08-21 put last traded $7.67 on 07/17 (now $8.20/$12.30) — try a limit near $8.20.
