As we can see NIFTY is now heading towards important resistance after a successful one sided upmove, we it was more like a one sided upmove we can expect some retracement now and since the zone maked in the chart has previously acted as a strong support, can now act as a stronger resistance and get some rejection making a successful head and shoulders pattern in bigger time frame for further upmove hence we should prepare for every rise as a selling opportunity till 16800 levels
