The trade is based upon 5min. chart so for very small time frame (today only trade). Dun buy at the highs, wait for pullback to 491.50 to 493 zone and some sort of confirmation to buy. The first target would be the vertex of the rising wedge @ 600 levels. The 100% of the morning bull move would be the next target @ 603.75
For better understanding of structure look for 5 min. chart.
