context.getHistory().getOrdersHistory(instrument, from, to); in onStart(...) should work or is that disabled for some reason?

Sorry, but it was more like an emotional expression! Some posts above, we have shown which rules are removed and which are added. Please read it carefully. We will also update the Contest Rules on the forum and the web-site today.

@Jakil
No, it won't work. Lets assume that you have 2 winning trades and 8 small zero-profit trades. The rule that we are going to apply will remove the first profitable position. But what happens next? We apply the rule again and it cancels the second big position until there are no any other positions which take more than 50% of the total profit of all positive trades. How do you need to trade? You need to trade with more or less similar profits on your winning trades. And it's a little bit tougher but fair!

@brainstorm
I am not sure that you need to keep info on mTotalPositiveProfit in your strategy and use it in your strategy!
What is the totalPositiveProfit when trades are not done yet? What if the first profit will be about 1$?

So, you either need to enable your mechanism when at least several trades are done and the totalPositiveProfit become really big. Or.. don't use at all! Make a strategy which trades with more or less even profits.

By the way, we don't recommend to use onMessage methods to manage existing positions. In some cases, due to a bad internet connection, some messages can be lost. It means there is no guarantee that the confirmation message will be received. There are some alternative ways how to define that the position is closed. For example, you can use IEngine and IHistory interface.

Yes, it perfectly works.

There have been questions about the amount of simultaneously opened positions. So, once again we confirm that there is no change in this rule - only 1 position group is allowed at a time. A position group can includes an entry order, a stop loss order and a take profit.

Thanks, I was not aware of that API. It used to not be possible to do that !

true, there are edge cases. We could start enforcing that only once we have a certain amount in profit for example. Thanks for the comment on onMessage(). I'll use the trade history instead.

Would onAccount() be a more reliable place to account for account activity ?

OnAccount is updated every 10 sec and provides you with an access to basic equity data, leverage, use of leverage, free margin. But there is no information on orders, p/l, commissions etc.

Hi,
I read in Contest Rules the following trading rule condition:
"margin cut level of exposure 200%"

could you explain it, please ?

Best Regards,
Fra

The trading conditions are similar to all demo account. As soon as the use of leverage reaches 200%, the platform will automatically cut 50% of exposure. This is how the margin cut mechanism works in the platform.

The summer is coming to an end, traders are getting back from their vacations and we are having the last day for the strategy contest of August.

Let's hope we will see some interesting and new strategies in the upcoming months from the refreshed minds of our traders.

Good luck and remember - you can register for the strategy contest of September until the 15th.

Also, do not forget to read the rules carefully.

RSS Feed does not return anything when opened from Firefox or Chrome.
Firefox - returns the general webpage of the contest
Chrome - returns the XML without data in it
IE - works fine

Chrome doesn't support RSS format but you can install an RSS extention. Firefox and IE are both OK but note that if there is not any position than the page is blank and no any trades are reflected. You can test it on own contest account.

I am looking at my strategy's current position, and I don't understand how the turnover is computed on the contest page...

for a position (not yet closed) of 2500K EUR/USD, it shows turnover of 3.17. How come ?

It's in US Dollar millions. 2500k * 1.28 = 3.2 about 3.17.

Hi,
contest rules incentive to use aggressive gambling strategy (that win a month and loose much or all the next month).
Wouldn't be better to have strategy that give good result for more time (more than 1 month)?
I suggest offering only 3 prizes for each month and giving
3 prizes for best balances for first 2 months
3 prizes for best balances for first 3 months
... until
3 prizes for best balances for 12 months

Best regards,
Frank

The idea to extend the contest period has a reasonable basis. We are bearing this in mind. As soon as the contest rules will become stable and we will finally find the most efficient and effective formulas, we will extend the contest period to a longer period. Of course, if will have support of other participants. Thank you for the feedback.
