You should be able to get the 4's on EWKS if your early enough in the morning either way 5's wont be bad either...with news and such EWKS is heading to higher grounds of 4's and 5's even without news this will be a momo play on monday and such.
u can buy monday morning before uptick .. depends on the volume .. if a lot of people are going to be ready sunday to hit it monday premarket , it can blow to 5' quick .. but slap the ask . GL
