Support of Nifty

As I have mentioned in my last post, Nifty will not go below the trend line showing in chart. as this trend line is supporting nifty since 2008, but if this trend line broke and nifty will remain below this line for three four days than it will create a big problem. if we go through the chart of Bank Nifty, we found the same trend line there.
