If we gap up on Monday it has a 90% chance to close that gap by 4 pm so short the shit out of it. Not all gaps are equal, but the Monday upgap will be a second gap.
And it is pretty obvious what you meant by gaps, only idiots question it.
Yes only idiots that belong to the 99% failed traders group would have such assumption that a 2nd gap will be likely to be closed. Let’s hope that is the case just like the 2nd gap during the Brexit vote, laugh...
