Nifty slowly drifting down is having occasionaly bear climax bars and moving down. Here, both bulls and bears not doing a great job. Bulls not have the force to pull nifty up and bears dont find excited to push it hard.
Trading in channel nifty is at the bottom of the channel and made a doji bar followed by a bear failure bar, continued by a bull body bar. so bulls and weak bears will book profit here pushing nifty to the higher trendline and good risk reward trade setup available.
