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. 64 contracts (avg 125 vol/day, 64 traded recently)

CALX averages only 125 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 $45.00 08-21 call last traded $1.40 on 07/17 (now $1.00/$1.40) — try a limit near $1.20. Also watch the $40.00 08-21 call last traded $2.80 on 07/17 (now $2.25/$4.10) — try a limit near $2.80; the $50.00 08-21 call last traded $0.40 on 07/17 (now $0.30/$0.60) — try a limit near $0.40. Most tradeable put: the $37.50 08-21 put last traded $2.34 on 07/17 (now $1.80/$2.70) — try a limit near $2.25.
