Hi sarlamonu,
definition of trend is different for every one. I mostly see a trend based on my cci method.
and other common method for me is like higher bottoms for uptrend, and lower tops for downtrend.
Whenever price breaks the recent higher bottom, which is broken in the case of cipla, downtrend is established. Now if the price action braks the previous high from here, which is around 350, then it will be uptrend establishment again. But if it fails to break the 352 and falls before that, then it will be downtrend. But for now downtrend is already established as recent higher bottom was broken to downside.
If you see the chart below you can see that, between the blue support and resistance, this share is trading a rangebound behaviour. it can still retrace upto 302 levels or even more, if something drastic happens. Higher bottom was also broken on 10th may.
