We are posting an example of a strategy which is fully compliant with rules. The strategy is based on 2 moving averages (with periods 7 and 14)! You can adjust the strategy and use it in the contest:

About the point 8 in Trading Rules :
What about using Encog library for Neural Trading ? Not allowed ?

Unfortunately, no! It's not allowed!

I like new rules, looks like my quantum strategy that I was running in April.

I have a question, can I add to position and merge if I want to? Or should I close the one I have and open another?

Kind regards, Yaroslav.

"The maximum amount of simultaneously opened positions is 1. [...]"

A merge requires at least 2 positions. This is now prohibited.

i don't understand this statement

7. Multiple order resubmissions are strongly prohibited and will result in automatic disqualification. The trading script of the strategy must include the validation on free margin and amount of simultaneously opened positions.


Especially (Multiple order resubmissions )
what does it mean?

Well, it does not make sense to send a new order on every tick if you already have a position in the platform. Another example, if you're trying to send an invalid order on every new tick.

Multiple submission means that you're sending the same instruction again and again without waiting for a response from the server.

In some cases, a mistake in the code may also result in multiple order submission. If you will encounter this situation, you need to carefully follow your strategy and upon getting a permission from Dukascopy you can change the code and recompile the strategy.

[list=]
sorry for my english

another question please :
am i disqualified if this case happened
if i bought eur\usd at Monday ( when my balance was 100000) and i closed the position at Friday with profit exceed 50% ( the balance =200000 for example )

[/list]

No, you're not. But we will either ignore your profit or limit the profit up to 50% of the balance.

As you're trading with a robot, you can easily check if the position already has a big profit. It's better to control it right in the script. We have already posted some examples on the forum. Please check them to learn how you can do that.

Hi,

I just wanted to ask, will the strategy be disqualified if it closes most of its trades by the function 'close on exit'? I mean that some trades are closed by SL/TP, but most of them are initiated by the code which closes the open position when the strategy is stoped. Is it allowed?

Thank you.

i mean maximum profit must not to exceed 50 % even

if the position has been opened for 5- 6 days !!!

No, the OnStop method must not contain any trading operations.

It does not matter for how long you keep the position, try to keep the profit of every position below 50% of balance.

Hmm... In April you recommended to use OnStop method for closing positions. The new rules do not contain any prohibition on using OnStop.
?

Our rules say that this is a contest of Automated strategies but not manual ones. By using any trading operations in the onStop method you explicitly indicate that you're closing the trade with manual intervention. It's allowed to have some manual trades but the total amount must not exceed 10% of total turnover.

If you didn't know about this, then I would suggest you to submit a new registration in the contest. We will remove you previous registration in the contest.

We will add more description in the rules for the next month to make it clear.

Can my sister participate in the contest one strategy modification of my strategy???
Is is not multiple registration?

And we want to use the same VPS...

Thanks

Yes, she has to register the same way you did.

As discussed previously, similar strategies are not prohibited.

It is not allowed to use the same VPS because the IP address is not unique.

Okey

But I have some problem
Your reply date was on Mon 19 Jul, 2010, 15:17
I had started the strategy 2 on jul 15. (contest rules) and at the contest rules page not contain anything about a unique IP just to have unique ID of the strategy.
Now we have the same ip address 1 computer on a single ADSL line and 1 router.
Strategy 1. HumpY4X
Strategy 2. Syster

What can we do to not disqualifi the two strats???
