Testing is critical in developing profitable EAs

New comment
 

The process of determining EA profitability can be both objective and subjective.

Indeed, there is no one cut fits all scenario and there are plethora of techniques in the market today.

Among others, testing remains to be one of the critical technique used to ascertain the probability of the profitability of a given EA.

Knowledge of EA testing, optimization and analysis of testing reports is key in indentifying weaknesses and strengths of a given EA and hence determining a profitable EA.

Here is a challenge, based on the attached Strategy Tester Report, spot one weakness and one strength of this EA

Would you consider this EA profitable? Please leave your comment

 
History quality at 40% ???
 
History Quality is 40%. Results are useless.

Thank but the algorithm behind history quality does not affect profitability and equity curve as confirmed on the attached reports

I spotted the first weakness and you don't agree with that...

Ok, good look with your EA...

And by the way... that visual curve on your reports doesn't match the real market world of trading... Overfitting, whatever... I don't care... with bad Quality history, to begin with, leads to nowhere...

Live Long and (maybe, God help you) prosper...

Ok then, put it right away on a micro-account and let us know the results...

Let you prove we were wrong...

right?

Nowadays it is very cheap to make a point regarding HOW an idea can or cannot be profitable... So, GO for it... and enlighten us...

Thanks for your input. The EA was tested on demo account which showed history quality of 40%. After your first comment above, I re-tested the EA on live account and as you can see, it shows 100% history quality.

As you can see from test reports, despite of a huge difference in history quality, from 40% to 100%, profitability quality is almost the same.  This raise questions on the algorithm behind history quality

 
It is easy to create a beautiful tester graph, it means absolutely nothing. Out of sample test is critical.

Houch!! I didn't create a beautiful graph, it was generated by MQL5 strategy tester. What do you mean out of sample test?

 

Again, with your such beautiful charts, it is the time to put this on a Micro account, right?

Go for IT and let us know!

Again, you charts are bizarre, unreal. Anyone who really experienced the whole cycle of studying, testing, backtesting and live-trading a newly born EA will tell you that.

Your post, from the beginning, is just to tease us about your Magical product that you will deliver soon... OR, you are totally clueless about how to read Optimization results and how to indentify a good Stragey... and you "challenged us" to discover it for you...
