I am taking the minute wise custom data of an indian equity(got from tradingview). The SMA values of all the minute data of the first day match with tradingview. But from the second day onwards the SMA values of the minute data is constant, On the third day, the values comes different, but it again remains the same the whole day. 

If the first day data is correct, I am unable to understand why from the second day the values are coming constant..
