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. 74 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 $30.00 08-21 call last traded $9.41 on 07/17 (now $8.70/$9.50) — try a limit near $9.10. Also watch the $40.00 08-21 call last traded $2.80 on 07/17 (now $2.40/$2.70) — try a limit near $2.55; the $37.50 08-21 call last traded $3.30 on 07/16 (now $3.50/$4.00) — try a limit near $3.50. Most tradeable put: the $40.00 08-21 put last traded $3.59 on 07/16 (now $3.80/$4.20) — try a limit near $3.80.
