On 12th Jan Nifty formed an ascending triangle, indicating price action will move up. On 13th Jan we had a spike movement in opening. At the end of the day, nifty formed a descending triangle indicating price action will go down. I have taken smaller time frame so that the triangles will be more visible. On breaking the triangle's base at 8375 Nifty can move up to 8300. History always repeats itself. If you check past history when new president step in to power in US, share markets will boom. As bank nifty has regained its strength, it wont allow nifty to fall further. Bank nifty is moving inside the rectangle. When it breaks 18750 it will go up to 18550. This retracement will last for 2 or 3 days only.
