The No Go area just got hammered in ETH...
What is ETH? It a farkin easy way to say Extended Trading Hours
Go or No Go comes from Jim Dalton, who only trades these areas and i like the lingo because it very descriptive. They usually involve the tops and bottom of brackets (ranges) that are well defined over several sessions. They also involve GAPs in RTH (Regular Trading Hours) where buyers or sellers can step in and reverse the market, or push through stops, as they did in ETH.
I hope intra-day traders don't find this too technical because its very basic market structure, involving no trend lines, fibb ratios, or anything like that. If you can't understand GAPs then its time to walk away.
