Here, do some research on this term... simply put, it's a trading tool used either from support or resistance or total price moves.... that usually will show a reversal area on a sharp move, either up or down...
With EESO trading for so long at .009 to .01 area, there had to be a ton of demand waiting to pounce on a 50% sale on EESO this morning.... so it was a NOBRAINER, imo, to place an order at the .0045 level... BTW, I already sold the new shares at .007 for a nice 50%+ trade....
