un-losable collar on Zillow

I'm now in 800 shares of Zillow. Earnings are in a couple of weeks. I just had the $51 covered call expire. Today is an up day AND the2nd bull candle in a row (which appears it wants to close below the 10 ema on the daily chart)

So, I'll get into a collar for about a .50 credit. This will be an unloable trade = my favorite!
