That's it, it worked. Seems to be because I set one buffer.

#property indicator_buffers 1

 

You have done everything correctly. I checked it - it outputs as it should (I can give you a screenshot).

I just added on top of it

#property  indicator_separate_window
#property  indicator_buffers 2
 

Помогите, плиз!!!

double Lots_simb[3];


if(( Lots_simb[0]*2)< Lots_simb[2]) // почему истина ?
{

Print("Lots_simb[0]*2=", Lots_simb[0]*2,"Lots_simb[2]=", Lots_simb[2]);
Open_Buy_otl( symb[0],( Lots_simb[2]/2- Lots_simb[0]));

return;

}

Gentlemen of knowledge, when the log in the tester says "Function not allowed in test mode" how do I know what function is not allowed?

Features and limitations of testing trading strategies in MetaTrader 4'

 

Hello, I really need some help! I want to make an EA based on an indicator. In the beginning, like in any indicator, there are these lines:

SetIndexBuffer(0,ExtBullBuffer);
SetIndexBuffer(1,ExtBull1Buffer);
SetIndexBuffer(2,ExtBull2Buffer);
SetIndexBuffer(3,ExtBull3Buffer);
SetIndexBuffer(4,ExtBull4Buffer);
SetIndexBuffer(5,ExtBull5Buffer);
SetIndexBuffer(6,ExtBull6Buffer);
SetIndexBuffer(7,ExtBull7Buffer);
Then comes the body of the program (int start()...) where the variables ExtBullBuffer are calculated... I want to make an EA, so I don't need SetIndexBuffer, but if I remove it, while testing variables ExtBullBuffer are not calculated (for all timeframe of testing, for all timeframes it generates 0, though it's not true)... Can you advise what to do? Thank you.

In indicator buffers, the buffer is initialized automatically as soon as you declare the buffer as indicator (not auxiliary),

in other programs (not indicators) buffers need to be initialized with the ArrayResize(ExtBullBuffer,Bars) function;

(if the buffer is not explicitly named double ExtBullBuffer[1000]; )

And initialization should be done in function where it is supposed to assign values to the buffer. In your case, in int start().

 

Hi all. Can you tell me how to fix the code of the indicator, so that the beep is output not once, but 10 times, or as there is an indicator where the signal until the next candlestick appears. That is, the signal goes all the time the candle in which it occurred. I have a good signal, but only once... Unfortunately, I can not hear it at night(((( I thank you in advance for your feedback.

What do you need it for? Tell me more about it, maybe there is a solution and you don't know how to ask the right questions so that people understand.

On what you have written, I have two solutions, you what, two at once too long to write :)

..

By the way, it's better to attach such long codes as a file.

And for the code, there's a special button SRC.
