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. 92 contracts (avg 581 vol/day, 91 traded recently)

CALX averages only 581 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 $40.00 01-15 call last traded $3.80 on 07/24 (now $4.10/$4.50) — try a limit near $4.10. Also watch the $37.50 08-21 call last traded $1.50 on 07/24 (now $1.65/$1.85) — try a limit near $1.65; the $35.00 01-15 call last traded $5.35 on 07/21 (now $6.00/$7.10) — try a limit near $6.00. Most tradeable put: the $37.50 08-21 put last traded $2.55 on 07/24 (now $1.75/$2.15) — try a limit near $1.95.
