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. 104 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 $150.00 11-20 call last traded $17.75 on 06/25 (now $15.80/$19.40) — try a limit near $17.60. Also watch the $145.00 08-21 call last traded $11.60 on 07/17 (now $10.10/$13.00) — try a limit near $11.55; the $160.00 08-21 call last traded $6.20 on 07/16 (now $3.70/$7.60) — try a limit near $5.65. Most tradeable put: the $145.00 08-21 put last traded $11.04 on 06/25 (now $8.90/$12.30) — try a limit near $10.60.
