Yes 50 points on downside is still possible. But normally after a 500 points on the DOWNside market does a U turn for at least 250 points, which would be 5500. Plus one more indicator is the MAX Pain still at 5500. So market can Revisit 5500 before Expiry or Market can even expire around 5500. But it is a Positional Call. Better to Trade 5500CE which is now available at @ 17.
