Automated entries don't work because during a specific time period of say 3months a specific pattern emerged that just happened to generate good returns on this 1 out of 1000 EA's you are running at the same time. This is why there is always a few people making good returns during the Metatrader EA contest, out of hundreds of EAs , the probability due to random luck that a few of them will just so happen to make money during a specific trading pattern that won't repeat itself(months 1,2), is very high. Keep on running the same competition over a year period and losing EA during the first period could actually be the winning EA during months 11,12. During any short period of time and taking a large random hodge-podge of EAs, some of them based on random luck will generate good returns, but during another arbitrary period these same EAs will fail.
For example an EA could align its buy instructions with phases of the moon during the EA trading contest for that specific period, but keep on trading on the phases of the moon and over a 12 month period the account will be deep in the red.
The market follows the 60/30/10% rule: 60% counter trend, 30% trend and 10% breakout. If the market just so happens to be in a trend during the EA competition then an EA tweaked for trends will do well but during counter trends will fail. The trading contents doesn't prove anything because the period is to short.
