What volume chart was that? It wasn't ES - well, it's certainly nothing like my ES volume chart!
Today's not a good day - the spread between high and low of the day so far is a measly 5.75 ES points, and less than 50 Dow points. When you have a big drop like we did yesterday it's rather like she's fallen down the stairs, and therefore after a fall, she sits at the bottom all dazed. That's what the market is doing now, recovering from the fall.
As the action is sideways, there's nothing much you can tell from the volume today.
On your first chart, you see that the price bars out of the starting gate were sideways, which is always tricky. Your short entry was ideal though, but for a short-term trade you should have exited on the first HH. For a longer-term hold you would have exited when you saw the right shoulder of the inverted head & shoulders.
But today is tricky, so far. I've not made a trade yet; just sitting here knitting and reading a book until there's some sort of pattern to trade off. I thought the inverse h&s might be good - it was nicely formed on ES, but had lower peaks on the Dow (not a good sign).
You can 'feel' that there is a move coming up - lull before the storm, etc.
The big picture head & shoulders we spoke about yesterday has now formed the right shoulder, and so you would expect a downwards movement to complete it. The price today looks as if it is a bear flag - easier to see on 30 min ES, so we might get a nice movement before the close of play today. If not, we'll get it Monday.
