We broke a critical level at 4400 and have been floating down in a channel to 4350 ever since. Now 4350 remains a crucial pivot.
Below 4350 we test 4300 and below that we test 4250. Hold 4350 and we can get back to 4370-4375 where Friday option data is showing a potential pin with 3500 contracts of 4375p short and 5000 contracts of 4370c short.
