OrderSelect gives weird result in strategy tester
hi! i've been writing an EA. and i noticed that OrderSelect wasn't acting as it should. so i wrote a simple test program, and OrderSelect still gives a strange result.
consider the following code:
for(int i = 0; i < OrdersTotal(); i++)
{
if(OrderSelect(i, SELECT_BY_POS, MODE_HISTORY))
{
Print("OrderTicket: ", OrderTicket());
}
}
Lets say that 5 trades have been opened and closed. the above fragment of code should print out the ticket number of those 5 trades. however, it only prints the first. OrderSelect fails and returns Error 0 for the others (Error 0 actually means "no error", so OrderSelect fails with "no error"?!). i have attached the test code which incorporates the above.
i spent 12 hours trying to figure this out so far. any assistance would be appreciated.
You must use
OrderSelect(i, SELECT_BY_POS, MODE_TRADES )
with OrdersTotal()
and
OrderSelect(i, SELECT_BY_POS, MODE_HISTORY)
with OrdersHistoryTotal( )
You can find more info in Metaeditor's help.

The 'problem' is with the indicator not your EA. The indicator is looking to draw in the first indicator window (the main window is 0). If the window doesn't exist, as in your case, you get a warning. You can either fix the issue in the indicator or just ignore it.

Help Coding a New Indicator
Hi,
(1st time poster
I'm looking for a friendly mql coder who could have a look at producing this indicator / alert based on pre-defined criteria.
All Im looking for is a visual alert on the chart (arrow above or below the criteria, with the ability to send and email if required).
The criteria are based exactly on Tom Striganos "Catapult for 80" setup, exact details are
www.strignanosforexsignals.com/catapult80.pdf
Summary of the above PDF link.
Catapult for 80 upside
Two important criteria, One: the bar before the execution bar must be a lower high(Green
Arrow) then the previous bar. Two the close must be a Down close. if you have met the
criteria you buy the top of the bar two bars ago.. Stop loss 15 pips below the middle
bar .Look for 80 pips, use market exhaustion..fibs all the tools you have been given.
Catapult For 80 Set up for the Down side.
Two important criteria One
The bar before execution has to be a low greater the the previous Bar.
Second Criteria You need a up Close. If you have Met the Criteria you sell the
bottom of the Bar (Two Bars ago.) Stop Loss 15 pips above the middle bar.
Red arrow on top. Look for 80 pips. 80 pips is what we are going for if it breaks below, use a
trailing stop, of course you can use Fibs as well to calculate exhaustion.
Any help much appreciated.
Thanks.

I wrote something today but it doesn't work as it should.
For long position everythig is fine (it doesn't modify short one).
for(cnt=0;cnt<total;cnt++)
{
OrderSelect(cnt, SELECT_BY_POS, MODE_TRADES);
if(OrderType()<=OP_SELL && OrderSymbol()==Symbol())
{
if(OrderType()==OP_BUY)
{
//IT WORKS:
if(Close[1]-Open[1]>0 && High[1]>P_BUY && Low[1]>D_BUY)
{
P_BUY=High[1];
D_BUY=Low[1];
OrderModify(OrderTicket(),OrderOpenPrice(),Low[1]-Point*1,OrderTakeProfit(),0,Green);
return(0);
}
}
else
{
//IT DOESN'T:
if(Close[1]-Open[1]<0 && High[1]<P_SELL && Low[1]<D_SELL)
{
P_SELL=High[1];
D_SELL=Low[1];
OrderModify(OrderTicket(),OrderOpenPrice(),High[1]+(Spread+1)*Point,OrderTakeProfit(),0,Red);
return(0);
}
}
}
}
Any ideas??
