Was scrolling through and noticed one of those high volume low spread bars on EMC, had a nice following upbar im assuming due to sellers being exhausted but met resistance fairly soon after (up another 20+%). Appears after a failed test to have quickly come back to test for supply around that high volume bar, being close to the demand line I'm thinking it might look to do something similar to the previous succesful test, already had a good test 4 bars back but seems to be just dipping its toes under that support line, looking to maybe spring or further low volume testing, or was that big volume the start of some distribution, worth keeping an eye on as it touches.
