Renat:

Fortunately, the problem of old configs is behind us. 50 builds ago is a very long time and we have allowed ourselves to change formats several times.

For the brokers we have provided not only a distributed distribution delivery network, but also a centralised repository of all distributions at files.metaquotes.net - this fundamentally solves the problem of timely updates of hundreds of copies of distributions for different companies.

In any case, my apologies for this unpleasantness - I'm sure it won't happen again.

In addition, we will now apply an even more advanced method of automatically and securely locating broker trading servers when connections to known access points fail. This will fundamentally solve the problem of publishing lists of working access points.

Thank God Alpari is sorted out, I think the release is now available there on the website 291. It remains for Admiral markets to explain that it is not necessary to keep the old version on the site - there is a 237 release weighing 7 mb... :)

Guys, what's with the cursor... It's definitely F7, it's popping out...

Instead of hosannas - just words...

and the hotkeys - please - bring back... it's not difficult... it's a habit - it's been drawn for years...


As for the hotkeys - accepted. The task is there.

It's a bit more complicated with the cursor. Still not observed even by the actions you mentioned.

 

I wrote such a situation, I tried to run it, terminal crashes.

2010.07.22 13:43:55 StandardDeviationChannel (EURUSD,M1) Array out of range in 'StandardDeviationChannel.mq5'(114,51)

Please indicate where line 114 and 51 positions are located in the attached code.
  
ExtUpBuffer[i]=ExtMABuffer[i]+(InpDeviation*E xtStdDevBuffer[i]);
highlighted in red
 
sergey1294:
highlighted in red.

Apparently your to_copy is clearly less than rates_total.
 
mql5:

Yes, to_copy=1.
 
Rosh:
Yes, to_copy=1.

and how can this be fixed? if it is one, why is it that when you remove these lines

      ExtUpBuffer[i]=ExtMABuffer[i]+(InpDeviation*ExtStdDevBuffer[i]);
      ExtDownBuffer[i]=ExtMABuffer[i]-(InpDeviation*ExtStdDevBuffer[i]);

the indicator starts working and displays МА

You have specified

#property indicator_buffers 4

and you set it to

   SetIndexBuffer(0,ExtUpBuffer,INDICATOR_DATA);
   SetIndexBuffer(1,ExtDownBuffer,INDICATOR_DATA);
   SetIndexBuffer(2,ExtMiddBuffer,INDICATOR_DATA);
   SetIndexBuffer(3,ExtMABuffer,INDICATOR_CALCULATIONS);
   SetIndexBuffer(4,ExtStdDevBuffer,INDICATOR_CALCULATIONS);
 
mql5:
You pointed out

#property indicator_buffers 4

but you did.

Thank you so much, I hadn't noticed such a small thing, it's OK now
