Nifty has been following these trend lines and break above or below it may result in big momentum movement.. on the downside we have a 20 EMA at 16725 below which we may see huge selling coming in. As per the volume profile Major support (high volume node) is some where near 15880. On the upside a break above the trendline resistance of 17200 may take u to 17350 - 450 very quickly. If nifty sustains above that then we can see a big rally also - but it will largely depend on the Russia-Ukraine-US news flow
