Income call
For income on OSK you already hold: sell the Oct 16 $170 call and take $80 now. If OSK climbs to $170 by Oct 16, your 100 shares are sold at $170, so only do it if you're happy selling there.
If it climbs past $170 your 100 shares are sold at $170 and you keep the $80. That is the trade working, not a loss.
