IS MY EA OKAY

jacques366 2009.01.08 13:10 #1

I had a brief look : a function is defined this way : FunctionName {....... code inside brackets ........} it seems you missused brakets.

int start()
  {
//-------------------------------------------------------------------+
   int cnt,ticket,total;
   double RSI_CURR,RSI_PREV,MA_1,MA_2,STOCHVAL,STOCHSIGN;
//-------------------------------------------------------------------+
  
   RSI_CURR =iRSI(NULL,0,14,PRICE_CLOSE,0);
   RSI_PREV =iRSI(NULL,0,14,PRICE_CLOSE,1);
   MA_1     =iMA (NULL,0,14,0,MODE_EMA,PRICE_CLOSE,0);
   MA_2     =iMA (NULL,0,7,0,MODE_EMA,PRICE_CLOSE,0);
   STOCHVAL =iStochastic(NULL,0,10,3,3,MODE_SMA,0,MODE_MAIN,0);
   STOCHSIGN=iStochastic(NULL,0,10,3,3,MODE_SMA,0,MODE_SIGNAL,0);
//-------------------------------------------------------------------+  I THINK YOU MUST CLOSE START HERE BY }
//+------------------------------------------------------------------+
//| Calculate Optimal Lot Size                                       |
//+------------------------------------------------------------------+  
double lot;                                             ....................... TO OPEN A FUNCTION DO NOT PUT ;
                                                        ........................ JUST functionName{.... 
{ ....................... HERE YOU ARE OPENING A ROUTINE CALLED LOT
   double dFreeMargin = AccountFreeMargin()*lot/100;
  
   if (AccountFreeMargin()<(10000*lot))
   {
   Print("we have no money", AccountFreeMargin());
   return(0);
   }

} YOU ARE CLOSING THE FUNCTION LOT                  .............

//------------------------------------------------
   total= OrdersTotal ();           ORDERS BUT NO FUNCTION HAS BEEN OPENED
   if(ticket<0)                   
   {
      Print("ordersend failed with error#",GetLastError());
      return(0);
   }

Hope it will help a bit, no time right now to go further.

tanx for your help jac, but i still cannot get the ea working, pls help me out guyz

jacques366 2009.01.09 14:05 #3

Do not panic. Correct your entire code and resubmit it if still not ok.

(In case you don't know: You can also have a look to the Book on this website, it will guide you thru the basic learnings you need to build a great EA.)

Will create your Expert How to code? Where is mistake with

jacques366 2009.01.11 09:11 #5

Please revise carefully your program. See what I mean in the extract of your code I have commented:

//+---------------------------------------------------------------+
//| request to close/open long positions 
//+---------------------------------------------------------------+ 
if((STOCHVAL>STOCHSIGN && RSI_CURR>50 && MA_1==MA_2)==true)   ('== true' is not needed as the result of a condition is either true or false and if statement is triggered only when condition is true)
{
//---------------------
OrderSend(Symbol(),OP_BUY,lot,Ask,3,Ask-stoploss*Point,Ask+takeprofit*Point,"bullish",0,0,Blue);
if(ticket>0)
{
if(OrderSelect(ticket,SELECT_BY_TICKET,MODE_TRADES))    what do you want to do if that if is true?
Print("BUY order opened : ", OrderOpenPrice());         because as there is no bracket opened the pgm will only execute this line
Print("BUY order closed : ",OrderClosePrice());   and then the other Prints what ever your if result is
Print("BUY order opentime : ", OrderOpenTime());
Print("BUY order closetime: ", OrderCloseTime());
Print("BUY order ticket no: ", OrderTicket());
Print("BUY order print : ", OrderPrint());
}
else 
Print("Error opening BUY order : ",GetLastError()); 
return(0); 
}
//---------------------------------------------------------------------

When you have more then 1 instruction to execute in a if statement, use brackets.

Advice : arrange your code in order to be readable, you will need it when it will become more complicated. Refer to this exemple to see what I mean : https://book.mql4.com/samples/expert

From the look of your EA, you need to sort out your { and }. I don't know how much programming experience in other languages, so forgive me if this is teaching 'Granny to suck eggs'. What you need to remember is that the indentation is not important from the point of view of what gets executed in your code, but the bracketing is... { and } define levels of scope for sections of code for example:

if (condition)

{

line 1;

line 2;

}

is not the same as

if (condition)

line1;

line2;

in the first example, line and and line 2 will be executed, but the second example line 1 will be executed if the condition is true and line 2 will be executed anyway.

I don't have time to go through your code and figure it out, but it will be a good learning experience for you to do this :-)... There are an awful lot of }s at the end of your code and that makes me a bit suspicious that you may have missed some out earlier and just added them at the bottom until your peogram compiled...

All the best
