As per my analysis, unexpeted movement is there due to budget day. if Nifty is going to sustain above 13967 and the Support trendline (green). which nifty broke earlier, nifty could go there to retrest (Gapup) and fall down till 13585 or 13147. On the other hand if Nifty opens gapdown, nifty could touch 13139 then move upwards till 13756.
