Let keep it simple in gauging the trend. I'd taken 5 EMA strategy to gauge the overall trend.
Simple 5 EMA strategy –
1)Candle closing above 5 EMA is bullish with supports at 5 EMA
2)Candle closing below 5 EMA is bearish with resistance at 5 EMA
Applying 5 EMA strategy to Nifty 1 year Weekly Charts we could find that currently nifty closed
below 5 EMA after a long time with resistance near 4292 zone. As the week is about to end 4292
levels should be keenly watch. A close above 4292 denotes still bulls are under control. Else weakness
to witness in coming sessions.

Your observation on nifty 5 day ema support is very infrmative. If I had known and followed your 5 day ema, I would have made lot of money. Thank you for sharing the info with everyoneregardshkreddy
