In 60 mins chart, nifty is holding the trendline, however is shows a double top, which will be confirmed if yesterday's low of 4535 fut is broken.
4580 is a level that i dont expect nifty to cross today. and if 4535 is broken it can slide to 4489 for intraday.
if 4580 is not crossed today, and we break 4535, we will see 4308 within this week.
