Observation 1 : Making 100% return on capital of 15 lac in 7 days, will annoy a lot of people.
Observation 2 : A lot of people will advise why you are wrong and are gambling.
Observation 3 : The fact that you are a gambler or a calculated risk taker would be decided by this : How you would have managed this trade if it had gone 5% or 10% against you? What was your SL level? (personally believe going all in or leveraged is o.k in a high probability trade, with strict SL levels)
Observation 4 : The question to ask is what did the winner do right? What can I learn from it and incorporate in my trading system?
Observation 5 : Unless a mindset is changed, the trading results will always be what it has been in the past.
