Now one might say that this is just a one off thing, my counter to that is that maybe you don't get this big move in one day quite frequently, but it always happens across 5 days to expiry. I will take this trade anytime where the risk reward is mind blowing. Even if you get 1 good trade in 3 months like this you can equate to 50 or even 100 failed trades. So who needs a Wipro/Infy/Eicher to get rich. Always plan your trade and then trade your plan. These examples are just illustrative in nature for you all. Don't go overboard with it. Do your own due diligence before trading on anybody's views.
