Firstly, when you put this into USD terms, Rs(a.k.a. INR) 50000 = 669.54 USD.
Right there, that tells you, in general, the pricing of the stocks he trades and the percentage moves his trading. His Rs 1000 losses = 13.39 USD, and the Rs 2000 gains =26.78 USD.
That said, I agree with his principles of Scalping (or intraday "swing") and keeping a fixed account size. OTOH, for a scalper, 100 trades a week is very low, a 40% win rate (which is meaningless for most everyone EXCEPT a scalper) is not very good, and to operate from your gut is just simply, a losing method.
Better than futures? I don't think so. 1 TICK of a MICRO ES equals 1.25 US = INR 93. Maybe he doesn't have access to CME, because that's pretty damn flexible for sizing, which he claims is why he doesn't trade futures.
I submit his success is relevant ONLY in his locale. It is not scalable to markets priced in stronger currency. He would fail miserably, imo. Worth a write-up? Only in his country. Worth a read? Not really.
