jinxu, why don't you start a journal and set up a new sim account and post the p&l everyday for one full month? If you do this and are profitable without a large drawdown I am sure you will have lots of pm's wanting to purchase it.
Wow. I looked at this thread yesterday, giggled, and then moved on. I assumed it was some random poser. Now that I see it's jinxu... I'm positively laughing out loud. I have to say, calling out a guy for a divorce is really plumbing new lows even for you, jinxu. Here's my system for a potential 200% return: head to Vegas, find roulette table, bet on black.
True, my performance is quite erratic but profitable with very few losing months. "Someone out there", "luck" - these types of words have little to do with long term trading performance, it's what's wrong with your mindset.
I'll answer that with a straight face. Yes, I think it's possible. See previous mention of heading to Vegas and betting on black. Leverage is all it takes to get 200% annual returns... once. As far as consistently getting 200% returns.. or even 100%.. or even 50% (unless your name is Jim Simons) with a reasonable Sharpe ratio? No, I don't think it's possible. I don't think it's possible, because no money manager in the world has ever done it... not even the billionaires. The fact that you firmly "believe" you can do it has no relevance on my world view.
200% return is very possible. In your case - you can't extrapolate 200% APR from your 10, 20 or even 50 trades during a timeframe of just a few weeks or a month. That linear hope based return curve meant nothing.
100% or 200% a year is absolutely possible with little draw down, if one day trades and the account is in 100k-500k range. Once size is increased the liquidity becomes an issue. 100k into 200k is not too hard for someone who knows what they are doing. 1bln to 2bln is extremely hard for anyone. So when talking about % per year, always add funds under management, otherwise it is meaningless.
