I had a triangle formation drawn on a 4 hour chart.

This morning I noticed some momentum while price played back lower into the triangle.

I sold at market with a tight 10 pip take profit. I made sure to keep this ABOVE potential support, to be safe.

Actually the price moved more than 30 pips past my take profit (through the potential resistance.) This WILL happen and profit can be left on the table, which is fine.

At this time the Dollar Index was moving higher towards a potential resistance area
