Good article, but can't you have the same result, and easier, with a simple EA using several graphs (one for each group of instruments)?
 
You would have to have at a min. 23 accounts running at a min 46 bots buy and sell hedge and re-hedge exit and hedge more. It's a never ending cycle, very complex monitoring each and every position in a way as not to erase ones signal from profitability, not as easy as the article above, its a very nice proof of concept. I love it.

As I stated before, you have the same result, and easier, with a simple EA using several graphs and just one account, to trade more than one trading symbol and use multiple strategies.
The only condition is: your algorithm must check the symbols and do specific operations, not generic, just for the group symbol you define, and you must have input parameters to define each group of symbols.

For instance, imagine a simple Moving Average Crossing EA, you just need adapt the code to be as simple as code below. This will enable any EA to be multi-currency multi-system in one account, and you can have 12 symbols and 4 groups of independent backtesting adjustment (period_MA1 and period_MA2).

// Structure of the multi-currency multi-system Expert Advisor using 1 account and multiple graphs

input string symbol1="EURUSD"; // graph group symbol 1 
input string symbol2="EURJPY"; // graph group symbol 2  
input string symbol3="USDJPY"; // graph group symbol 3  
int period_MA1=14; // period of moving average 1
int period_MA2=9; // period of moving average 2

// algorithm symbol test (execute the strategy algorithm testing the name of the symbol)
if (...==symbol1 || ...==symbol2 || ...==symbol3) {
   ...
}

I agree its great have one EA for 12 symbols even more if your into exotics. Indicator data is not accurate. Example IBFX opens after FXCM and FXCM open after Dukascopy the moving average would be off, so would all the other indicators. Its a parlor trick, Real Economic data and Economic Indicators that don't rely on opening or closings but price alone. technical indicators are great psychological indications of public perception of price for speculation. The market place is so much bigger and correlated and to rely on only 1 ea with a couple of tricks to get by would only result in a bad EA later down the road, it may work for 2010 but not in 2012 nope thats not for me. Multiple EA's hedging against psychological perception vs hard economic data positions, responding to Commodities , Securities, Gov Debt. pushing hard numbers and seeing how the world's market places respond and adjusting my position accordingly with the release of the data against all market sectors. Its very complex. MQL5 Language has come alone way and I love to see progress such as the article I read. I see progress that allows people to only be limited by there imagination. I am building on the code and developing a framework like I said its a great proof of concept. I see amazing things coming on the road ahead for metaqoutes and the people who dedicate there time.

I am new to this business but I think that writing Expert Advisors through MQL5 is not too complicated and can be learnt by examples!!!! I am very grateful to the administrators for such a detailed description and examples:)))))

Hello.

This code of EA is exactly what I'm looking for.

However, I'm doing it semi-auto with my custom EA with 15 symbols

though, I'm only controlling 2-3 at most. Would there be any version for

MT4?

 

Thanks. 

 

Furthermore, I'm not using any indicators; my account equity is my indicator...

 
I tested strategy A for GBPUSD for same period with same settings in mt4 but my results are not same. Any idea why?
 

i have a simple question here.  If, say, the code within the OnTimer takes more than 1-second to execute on average (such as 2 or 3 seconds), should i change the EventSetTimer within OnInit to a higher value (such as 5 or 6 seconds) ?  Thanks.

==========================================

int OnInit()

  {

   //--- Set event generation frequency

   EventSetTimer(1); // 1 second

   // ...

   return(0);

  }

 
How to consult the floating profit? The open volume? Number of Positions?
