Currently the SPX, while still in an uptrend, is stuck in a channel between 3000 and 3230.
It has again bounced on the 3000 support this week and is continuing upwards as expected.
First resistance is at 3090. If that one fails we drop to 3000 again.
If it breaks out we should see a quick run to the 3150 resistance and then 3230.
I'm currently long and planning to sell at 3090. Then I'll wait for confirmation when 3100 breaks to buy back in, or in case of a failed breakout, for 3000 to buy back in.
