Test failed

New comment
 

Hi guys,

I have a question for you - maybe there was similar, but I did not find it -

I created an EA bot. On every Strategy Test worked well everytime and the performance was really good. (different months, different settings...I tried it on many ways)
Then I added to a Demo account for a real test and it was a failure...but I dont know why.

Of course the market is not same...and everything is changing...but I dont understand why it works on strategy test and does not work on demo account.
Does anybody have any idea what should I check...?


Thanks your feedback!

(if this is a stupid question...please dont kill me) :)

Apply the following knowledge to your EA. It is just as valid even if you do not plan to sell it in the market.

This happens because you are testing your system in a wrong way.

If you coded the EA you should be aware of how delicate it is about ticks and little changes. If you are on MT4 the most possible cause is that you are trading around rollover hour with a fixed spread that is so far from the reality.

But it can also be that you have not accurate datafeed and your system is very tick sensitive.

In a correct environment, an EA should backtest and trade into the same exact way, but we have no information about your system and your settings, so the cause can be any.
