When the use of leverage equals to 200%, the system decreases the exposure by opening new hedging trades. The use of leverage will be reduced to 100%. It does not matter when margin cut took place.

Hi Contest Support,
I need your help.
I tested my strategy with Historical Tester without trouble, but when I ran it with demo account (local run) I received the following message from server:

the first order was with
equity = 100000
lot number = 383.05
amount = 3830500

but the server replied
"Insufficient margin. Filling maximum allowed amount 7689000"

and opened the first position with maximum amount (using all margin)

the first position was closed with profit
equity = 130473

then the line that calculates lot is very simple

double equity = this.account.getEquity();   
int percent = 50;
int margin = 100;

lots = (equity *percent/100)/ (margin * bidBar.getOpen())  ;

when the strategy sent the second order the server replied
"Your order has been rejected due to validation failure. order amount can't be greater than 500'000'000"

Best regards,
Frank

Hi Frank, if i understand your stuff correctly you are using the open price to calculate your lot size.

I am not sure what's the deal behind that; could you develop?

The code i am using manage the lot size depending of the stoploss and looks like the following:

EqAtRisk=5;
stopLoss=20; //20 pips
tickValue=1000000*instrument.getPipValue(); //1M is Dukascopy standard size
riskAmount = this.acctEquity * this.EqAtRisk/100;
myLot = (riskAmount/stopLoss)/tickValue;

So booth (weekend and business day) rules close at 200%? (weekend particualry, business whole)
am I right?

Hi Frank! Lot amount is indicated in millions. The validation message says that the order amount is too big. Please check it in the scrip. You don't need to indicate the amount in units or thousands!

The mechanism is the same. Once the use of leverage reached 200%, the system reduced the exposure to 100% of the equity. The only difference is in leverage. Over-the-weekend leverage is 1:30, while the normal leverage is 1:100.

It's nearly the end of September and the current top3 traders haven't reached the necessary amount of trades, so PipsCity has a good chance on taking this one.

Also dear traders! Prepare your strategies very carefully for October, we are expecting some serious competition.

Hi,
I am developing the code for the next October contest,
but I have 3 questions:

-My account appears as 'inactive', so I can not compile the strategy code.
- Where I must compile the code? Which steps i must follow?
-What happens if a first position winner can not fly to get the Watch and
be suitable for a interview?


Thanks in advance.

- You need to register for the month of October and you will receive a new demo account.
- You must compile the code on the platform. You can read more on how to compile and run a simple strategy on our website ('Forex Trading' -> 'JForex' -> 'Documentation' -> 'Getting started').
- Participants of the strategy contest are eligible only to the prize money. Please read the contest rules on our website ('Forex Trading' -> 'JForex' -> JForex contest'). You can win the watch if you are a live trader.

Hi,

'The maximum amount of simultaneously opened positions is 1'
What is the main reason for this rule in the contest ? I think it is useless.
It blocks me to trade multicurrency pairs, eg correlation and cointegration between EURUSD and USDCHF and others similar. For example if both pairs are in 'oversold' zone on a specific timeframe then there is a very good chance one to revert back since these 2 pairs are negatively correlated. There is no real reason both to be in the same oscillator extreme area; just an example; and I had a lot of ideas to test using multicurrencies/instruments at once.
I would appreciate this rule to be removed from Octomber onward.
Thank you.

The idea is to prevent gambling and extreme positioning.

This matter is discussed in "General discussion and comments", starting from page 6.

Hi Darlu



I'll second that. If you want to trade forex as a business rather than as mere "gambling" then diversification of both systems and pairs is vital.

I too would much appreciate it if this rule could be modified to permit multi-currency trading in the October contest.

How about it Dukascopy?

Jim

P.S. Whoops! - Was typing that in when support's post appeared. I'll head over there now.

Hi Contest Support,
I noted that the number of Total Trades of partecipant "ipleX" and the number of Total Trades of partecipant "daffyduck" seem increasing synchronized and even the times of trades appear similar.
Are they simple Coincidences ?
Could you, Constest Support, investigate, please? (verifing IP addresses, starting and ending times of strategy, ... and so on).

Best regards,
Frank

Ok, I am a bit unclear what means a position. The question is:
- May I have instant orders SELL and BUY in the same time on the same pair ? Is this considered only 1 position ?
In the Positions group tab I noted 1 postion but in the Positions tab I have 3, which are in fact 3 instant separate orders SELL, BUY, SELL on the same pair. Are these 3 different positions ?
Thank you.

They are considered as three different positions. This is not allowed.

I asked because I found many participants including the ones that are/were in the top using trades like below. Maybe I am missing something.
I dont blame anyone, just want make things clear for me. thank you.

Now their positions looks a bit different and when I looked at their portfolios there were traded two different pairs. Guys had similar growth probably untill your info (if you look at their equity chart) and there is difference at rate turnover/no.of trades. So there is a difference for sure.


Good luck for all contestants !!!

Is it needed to register a new account for each month I want to participate in the contest or can I use the same account over several month?

No worries, we will investigate all accounts in the contest starting from tomorrow as today is the last day! We already have a list of suspicious trades that we would like to scrutinize.
