One of the Keys for having a good EA is an automated testing system, My system can deploy tests automatically on many computers at once and that way reduce the overall time.(it is deployed on Amazon EC2 and Google App Engine, it can also be used on any computer network) and it is all done through a simple web interface.
It can run on any EA (expert advisor), and it saved all the data in a database for later use.
Each test saves the Preset In the database no need to keep it at your file system.
The Table below shows the test results filtered for one pair EURUSD for 5 years, it can also filter per date.
by clicking on a row you will get into another page that shows all the details for that tests including all the positions that were made in the tests and a detailed summary that MT4 produced.
The graphs below shows the totals for each year tests, each year it ran 10 Pairs.
The Graph below shows the equity and leverage for every hour combining all tests for that year together:
If you have an EA that takes a long time to test contact me maybe we can save you a lot of time.
I don't see anyone succeeding on making a good EA without a very good testing system that can show you what are the limits of your EA.
Running an EA without thoroughly testing it is like flying a plane without enough fuel - you will crash and burn.
