First I make it clear I will not mentor anyone.
This day I prefer not to come to Elitetrader to waste my time to deal with some idiots, but rather make $$$ from the market, or spend time with my family or playing with my new toy (car price drop by at least 50% in the first 3 years so I better enjoy it before the the $60K/year depreciation kick in).
My only advice, all the trading systems (retail or even professional) are down to two scenario - Trend or mean reversion. You can have the 3rd scenario with options (side way, our Bobby favorite, good luck for him in long term). The unfortunately situation is you can't find any system that will work in all the 3 market scenario (you can get it work for 2 out of 3 using Options but with terrible risk/rewards). All the system will work well in one market condition and fail in in another, in long term you will loss due to slippage & commission. Arb is not part of discussion here.
The key (I repeat again) is to find a way to know what is the current market situation (trend or mean reversion), and how (this is important) to know the time when the transition happen (trend become mean reversion or vice versa). Hints, you can't do this purely from technical, experience and common sense did matter.
All the best.
May that day come soon for you. And us.
