Dude..
Feb 23- FEB 28 - 1.8 million shares traded ( M-F)
Look at March 02 - March 06 - 1.7 million shares ( Monday - Friday)
March 09 to March 13 - 1.6 million shares (monday - Friday)
Several days in FEB had more shares traded than on the 13th....
Volume is more or less the same...nothing out of the ordinary...
