This trade can turn out to be a great trade. Should always stay flexible in mindset.
If didn't exit as traded, would have got stopped out but tape reading was good so still managed to make small profit. 
For squeeze like that should set an alert at the low again. If it is powerful it should not touch the low again. In this case it does so it's not looking good.

In fact, when it broke the low again it went all the way down

Bought in too late.. I should have bought in when it broke PM support. My mistake is I didn't notice I was close to a zone level with SPX because I was looking at spy. Note to self, pay attention to all charts!
