There used to be a tournament conducted by futures first called trade mogul, which was to trade on S&P, Oil, Gold and eur-usd. I came 2nd in india in that tournament, they called the top 25 for interview, I got rejected in the interview round, they said I am too old to learn trading and my risk apetite is very small as per their aptitude test but I had taken large risks in the tournament which contradicts themselves. That was two years ago. I came 2nd just by taking huge risks with normal method, but if I had done the same thing with real money results would have been drastic
So, any tournament that evaluates you as per return percentage is not a good method of evaluating trading performance as per my view as each person has different risk apetite.
I prefer zerodha 60 day challenge rather which does not rank traders but applauds those who are consistent in their performance by refunding all deducted brokerages.
