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. 107 contracts (avg 580 vol/day, 106 traded recently)

CALX averages only 580 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 $37.50 08-21 call last traded $1.93 on 08/06 (now $2.40/$2.80) — try a limit near $2.40. Also watch the $40.00 09-18 call last traded $2.15 on 08/04 (now $1.65/$2.00) — try a limit near $1.83; the $40.00 08-21 call last traded $1.12 on 08/05 (now $0.00/$0.35) — try a limit near $0.18. Most tradeable put: the $40.00 08-21 put last traded $2.93 on 08/06 (now $0.00/$0.45) — try a limit near $0.23.
