Alternative count: Suppose if wave (x),red color completed at 10:30 (Jan 25), fall from 10:30 is final part and almost completed, just z pending.
Max level it can fall further (should not go below this level)
Nifty : 14144 , Banknifty : 30718
To confirm that trend is reversed, it should cross this points from tomorrow low
Nifty: 301 , Banknifty: 10015
Either case - whether this alternative or previous one, fall may not continue stronger and there may be pull back as described
