Hi all,
need some help with an EA.
I have build most of it, but happend that it executed only 1 trade at time, and once I have a trade on it doesn't execute anything untill the trade is close...
I would like to have the EA executing up to 5 different trades,
 and to open a new trade not earlier than 60 bars after last trade was open.
couls somebody help me?
thanks

You probably have code in there that checks existing orders and if there is one sets a flag. Something like.

IsTrade = True

This flag is then probably checked in the order creation routine. Something like
if ( !IsTrade )

You need to replace this with code to count trades using the OrdersTotal() built in function if you are checking both market and pending orders.

For the 60 bars thing then I would set up an
'int count = 60 '
when you raise an order and then use a new bar function to count it down.
NewBar function is here

bool NewBar()
{
   static datetime lastbar = 0;
   datetime curbar = Time[0];
   if(lastbar!=curbar)
   {
      lastbar=curbar;
      return (true);
   }
   else
   {
      return(false);
   }
}

Then use
if (NewBar() == true) Count = Count -1.


11:15, restate my assumptions: 1. Mathematics is the language of nature. 2. Everything around us can be represented and understood through numbers. 3. If you graph these numbers, patterns emerge. Therefore: There are patterns everywhere in nature.

Hi,
I have implemented the max of 5 open trades;
but no luck with the 60 bars stuff...
please could you make it easier, or with more explanations?
thanks for your help.

OKay, you need to put the newbar function either at the end of your program after all the other code or at the start, depending on where you generally define any functions.
Then in your initial variable declaration use
int count = 60;

Then within the init start section somewhere enter

if (NewBar() == true) count = count -1;

Then within your trade logic add the test for
count <= 0;
Then whenever you raise a new trade reset
count = 60;


I think! Kind of tricky to write code in my head.

You need to declare it in your variables declaration section

int count = 60;

ok, here is a part of the code:
if I do this way, than I have 2x errors below:


int BarCount;
int Current;
bool TickCheck = False;
int Count = 60;
bool NewBar()
{
static datetime lastbar = 0;
datetime curbar = Time[0];
if(lastbar!=curbar)
{
lastbar=curbar;
return (true);
}
else
{
return(false);


int init() { ERROR HERE:'(' function definition unexpected
   BarCount = Bars;

   if (EachTickMode) Current = 0; else Current = 1;
     return(0);
   if (NewBar() == true) BarCount = BarCount -1
}


//+------------------------------------------------------------------+
//| expert deinitialization function |
//+------------------------------------------------------------------+
int deinit() { ERROR HERE:'(' function definition unexpected
   return(0);

Put your newbar function at the very end of your code

No errors, finally,
but now it doesn't trade at all.
