I started to try it and this is the result:

It gives an error:

Almost all functions need to pass three parameters. Symbol, Magik, and type of operation

belck:

you have :ticket=OrderSend(Symbol(),OP_BUY,Lots,Bid,3,Ask-stoploss*Point,Bid+TakeProfit*Point, "macd sample",16384,0,Green);

we need: ticket=OrderSend(Symbol(),OP_BUY,Lots,Ask,3,Bid-stoploss*Point,Ask+TakeProfit*Point, "macd sample",16384,0,Green);

and change here: ticket=OrderSend(Symbol(),OP_SELL,Lots,Bid,3,Ask+stoploss*Point,Bid-TakeProfit*Point, "macd sample",16384,0,Red);

It's correct:

ticket=OrderSend(Symbol(),OP_BUY,Lots,Ask,3,Ask-stoploss*Point,Ask+TakeProfit*Point, "macd sample",16384,0,Green);

ticket=OrderSend(Symbol(),OP_SELL,Lots,Bid,3,Bid+stoploss*Point,Bid-TakeProfit*Point, "macd sample",16384,0,Red);

Has anyone already encountered a situation where the tester only runs on one or two timeframes and gives an error on the others:

2010.10.12 10:02:29 TestGenerator: write file error

In the archive of quotes, everything is OK.

It turns out that I can only test on H1, for reasons I don't understand.

Is there any way to correct this error?

Hello, help who can, I am learning to write, I tried to write an Expert Advisor by the tutorial, but the compiler gives out an error, please explain what's wrong.

Hello, Could you please help, I am learning to write, I've tried to write an EA using the tutorial, but the compiler gives me a error, please explain what's wrong.

you have a link to the file at the very beginning #include <MyLib.mqh>

The compiler does not find this file in the include directory, apparently this file contains three undefined procedures required to work, search for the file and paste it where needed, it should work...

if it's not the error, at least tell me what the error is...

Thank you. I forgot to point out what I was swearing at, namely #include <MyLib.mqh>, thanks again.

The script just shows if the candle meets a certain condition.

//+------------------------------------------------------------------+

//| script program start function |

//+------------------------------------------------------------------+

bool CandleQualifier(double High[1],double Low[1],double Open[1],double Close[1]) // Here compiler writes High - parameter definition expected

{

double MidPoint=0;

MidPoint = (High[1]-Low[1])/2;

if (Open[1]< MidPoint && Close[1]<MidPoint)

return(true);

else

return(false);

}

int start()

{

bool CQ= true;

CQ = CandleQualifier();

if (CQ=true)

{

Comment("the candle qualifies!)

}

else

{

Comment("the candle does not qualify!");

}

return(0);

}
