&gt;sell 80 SPY 267put 
  
 Does that mean that im using my original 80 Long SPY 269 puts as the collateral? Doesn't selling 80 spy puts require like 8000 shares of spy? I never touched selling contracts because i heard its dangerous and that was enough for me to never touch look into it.

Yes, the SPY 269puts are the collateral.
