Weekly charts shows overheating of nifty, but looking at the trend, I see a double top formation today. So it is better to be on the sidelines and short when nifty touches the previous top.
Also, if you see the daily chart, you see two gaps,
- between 5645 and 5680
- between 5438 and 5519
This has to be filled before any further upside.
The weekly overheating factor can assure that there is no further upside. If this happens, keep daily tenken sen (5651) as target.
