At weekly level Nifty has closed with a Doji pattern. This indicates that after three weeks of successive gains traders are slightly indecisive about future marktet move. This indecision also gets highlighted in the daily chart below.
At daily level also Nifty failed to breach the crucial 5900 mark today and closed at 5842 points. Breaching 5900 is crucial to come out of the downward trend line. But, Nifty has closed today under that and now stands at a crucial support and if it falls below 5800 it may slide further.
