ANET Arista Networks Options Ahead of Earnings

Analyzing the options chain and the chart patterns of ANET Arista Networks prior to the earnings report this week,
I would consider purchasing the 280usd strike price Calls with
an expiration date of 2024-2-16,
for a premium of approximately $18.25.
If these options prove to be profitable prior to the earnings release, I would sell at least half of them.
