It is hard to say DIA looks bearish at this point.
Biotech is definitely flashing warning signs although it is set up to bounce this week. This sudden increase in range and volume don't bode well. I will be very actively watching this one in case a strong bearish scenario appears. This one has home run potential.
IWM dropped out of its channel/ wedge to much delight of the internet bears but I would like to see its reaction Mon/ Tues before getting too excited here. If it does follow through, SPY/ DIA might be good shorts.
QQQ made a vigorous bounce Friday and has a chance of putting in another leg up. If there is an index that has upside, this is the one to track but the false breakout should give warning to those going long.
The SPY fade scenarios. The oversold spikes have given back some the next day, especially the strong ones. There are lots of possibilities here so it's best to be very nimble. I am working primarily with 15-30 -60 min frames to line up entry points.
SPY could easily continue in its slightly upward froth for a while. An ideal situation would be an overshoot out of the wedge that fails as a short entry. On the long side, I would want the choppiness to diminish to feel more confident about scaling up.
