Very Bearish Call Credit Spread (at risk: $25) for 9/15 expy

VFS

Very bearish Call Credit Spread. Based on the expectation of a huge drop between now and expiration on 9/15.

+1 $55 call 9/15
-1 $50 call 9/15

Credit received: $475

If the share price is NOT below $50 on 9/15 I will have to buy to close for approx. $500 (plus maybe a couple more bucks to get the order fill). Another risk is the short strike could be early assigned. But either way, the loss would be ~$25. If this thing falls big best case scenario is that I will walk away free and clear with the $475 credit received.
