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. 70 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 $35.00 08-21 call last traded $3.60 on 07/17 (now $3.10/$4.10) — try a limit near $3.60. Also watch the $35.00 01-15 call last traded $7.78 on 07/07 (now $5.20/$7.30) — try a limit near $6.25; the $40.00 01-15 call last traded $5.70 on 07/10 (now $4.00/$5.70) — try a limit near $4.85. Most tradeable put: the $35.00 10-16 put last traded $2.90 on 06/30 (now $2.05/$2.60) — try a limit near $2.33.
