Test of an EA based on ticks - page 4

 
My understanding is that it will depend a lot on the broker.
 
Ibragim Dzhanaev:

Please speak up if you have any real knowledge.

How much of what the tester shows will correspond to actual trading?

I have an Expert Advisor working on ticks (only ticks are analyzed, TF is not used). To what extent the results correspond to real trading

. . .

A week ago I also tested some EA for 2010-2016 and got amazing results on real ticks with max drawdown ~3%.

And started to study this "perfection".

I discovered this: at the beginning of the test it thinks for a long time (of course after loading tick data), something turns inside, and then starts the test with a colossal speed with no drawdown, skips some days, sometimes half a month.

And those days tested after the last update of the Expert Advisor are not like a test before the update.

Although the test is running on real ticks, most likely this EA first analyzes all ticks for the specified test period, identifies (virtually) those days where profitability is high with a smaller drawdown, saves those days in an array or in a file, then starts the test using only those profitable days that were saved.

These doubts of course were not, if this Expert Advisor had a corresponding signal, so you could check. And unfortunately many naive users believe it.

P.S. As they say: "Not caught, not a thief".

 

I have long used self-written indicators that simulate trading instead of a tester.

This approach allows the test to be done instantly.

I advise

Well no, that's from a different line altogether.

Can you be more specific? As much detail as possible, so that I understand.
 
Ibragim Dzhanaev:

The indicator simulates the trading strategy, calculates Equity, drawdown and so on.

You can set the strategy input parameters in the indicator in the same way

But you have to write it yourself

That's probably all

I do not understand anything, but thank you.

New test. The results are better, because in the first case the trawl did not work correctly. I have added what you have asked for.

The easiest way to check if trades in the same period in the tester and on the demo are the same. If they don't coincide, then check if the profit in the tester and on the demo, at least approximately. If you want to check whether they coincide with each other. It seems it is not difficult to deposit it on the demo for a week.

Why do we use H1 period if we trade on ticks?

I can only see the report. Asked for the last lines of the tester log, where the slippage details are.

ZZZ The bug in the report is revealed - withdrawal is not shown at the end but at the beginning.
