What is best EA ought to be?

I have developed many ideas into EA and truely some are craps some are profitable but not last long. They are not conform to market fluctuations.

For a number of EAs, they are profitable during the right fashion and worst at ranging or MC at inverse trend
For some EAs, profitable at the ranging only, worst when fad happens.

I really do believe other developers also facing similar experiences.

So recently I had a new idea:
Forget about some other trade secrets, one need only a good system to cope with 3 items (TREND, RETRACE,REVERSE TREND)
Yes, only this 3 main things..other compared to MM

to come up with EA that may adapt to market change automatically so called
1. Follow trend, sure profit
2. Retracement, nevertheless profit
3. Reverse trend, have to coping with some floating but finally still end up with profit

Had tested in the month of Jan 2011 Feb 2011 market conditions ( I like this two months since it consist of the 3 previously ).

Results so far:
with depo sum of $1000, begin lot dimensions 0.1 (10 cents/pip on account leverage 1:500)
Jan profit 50%, with maxDD 50 percent
Feb profit 60% with maxDD 48%
March nevertheless testing. . .results so far 28 percent 10 days trades...

could possibly be due to a lot of calculation demand, I can't make the test quicker.
