TCS has completed long term correction phase as well as completed C&H with depth of around 1100 points with neckline around 4041 so that gives a target around close to 200% fib retracement that is 5163.
NIFTY IT index is also near to close the C&H pattern and if that happens that will pull most of the healthy IT stocks i the rally and TCS is the leader.
I would wait for this month closing and if it closes above ~4300 (above yellow line) then the trade will be active. If stock moves higher then would buy like to buy on retest.
