The key level to watch into the close is 13029.50. Trading on the weak side of this level will put the index in a bearish position.
The early price action suggests the direction of the index into the close will be determined by trader reaction to the pivot at 13623.00.
The close under 13872.00 formed a closing price reversal top. If confirmed on Wednesday then look for the start of a 2 to 3 day correction.
