let me explain
so with the short term bottom in place, an oversold condition into the bottom, for a first retest, is USUALLY successful.
also, depends on what time frame is looked at... the 8/11 pre-market can be considered the first retest, on a shorter time frame..
in anycase, today's open was a low risk opportunity.
this types of chances will occur many times in the coming weeks, as the strong emotional spots do exist on the charts now.
