While identifying the precise end point of an extension is often a challenge, you can become quite rich by joining in once the extended wave 5 finishes.
Typically, a market comes down to the level of 2nd wave of the just completed 5th wave
So i assume Tata Motors is a buy @ 169 to 170 with a SL of 165 for a target of 180
Disclaimer - 1) I'm a learner
2)I do have long positions in Tata motors
3) This is only a 15 minute chart !!
