Nice response on EGH today. Friday's big effort small spread bar followed up yesterday with what I can only read as a test of sorts, extremely low volume small spread, closing high but only thing excluding it as a test is none below previous close. Ideally does this read as a no demand bar? If anything it completed a shakeout over 4 days? Today's bar pushed through several lines of potential resistance with a spread only equalled by the recent shakeout on similar volume and another in late June on lower volume which did have its low retested later.
It's fascinating that such a high volume bar can be followed by such a low volume bar the next day and yet be holding enough pressure to follow up with today's bar.
