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. 102 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 $145.00 08-21 call last traded $11.60 on 07/17 (now $2.75/$5.20) — try a limit near $3.98. Also watch the $150.00 08-21 call last traded $9.77 on 07/17 (now $1.05/$4.00) — try a limit near $2.53; the $165.00 08-21 call last traded $5.00 on 07/16 (now $0.25/$1.55) — try a limit near $0.90.
