You may find the best point moving OBJPROP_XDISTANCE and OBJPROP_YDISTANCE

if I change the value for OBJPROP_YDISTANCE to 500

the label is not moving one pixel

//--- create object
  
   ObjectCreate(0,objectName,OBJ_TEXT,window,0,0);
 //ObjectSetString(0,objectName,OBJPROP_TEXT,string(ExtRSIBuffer[rates_total-1]));
   ObjectSetString(0,objectName,OBJPROP_TEXT,DoubleToString(ExtRSIBuffer[rates_total-1],2));
   ObjectSetInteger(0,objectName,OBJPROP_COLOR,Red);
   ObjectSetString(0,objectName,OBJPROP_FONT,"Arial");
   ObjectSetInteger(0,objectName,OBJPROP_FONTSIZE,20);
 //ObjectSetInteger (0,objectName, OBJPROP_CORNER, corner);
   ObjectSetInteger(0,objectName,OBJPROP_XDISTANCE,0);
   ObjectSetInteger(0,objectName,OBJPROP_YDISTANCE,500);
   
   datetime tm[1];
   CopyTime(_Symbol,_Period,0,1,tm);

How can I put the label into the upper right corner?

We are going to examine this matter, thank you.

Rosh:

You should learn MQL5 a bit before writing such indicator. You have made so awkward mistakes.

I am trying to learn but not exist simple tutorial or courses for mql5: i must learn from mistakes and ask for your help.

I cannot understand this instruction written from You:

 int i=prev_calculated;
   if (i>0) prev_calculated--;
   for(;i<rates_total;i++)

there is an error when I compile.

I have mistyped, sorry. Right is

 int i=prev_calculated;
   if (i>0) i--;
   for(;i<rates_total;i++)

Here is more right code, use it, please.

Rosh:

Here is more right code, use it, please.

I removed this istruction

 int i=prev_calculated;
   if(i>0) i--;
  /////// if(prev_calculated!=0) return(prev_calculated);
   for(;i<rates_total;i++)

because the histograms were not updated to each price change.

The I think that the problem can be on ( return).

is correct?

thanks for you help

......I'm doing other changes.....

You are right, it was implemented for debug purposes. I have deleted it grom my post.

antonio 2010.02.02 22:41 #28

I have modify the program for obtaining the colour of histograms but does not work.

I think that the problem is in counter.... in the cycle FOR..... is it correct ?

We are going to examine this matter, thank you.

I made a proof-of-concept EA interacting with an indicator through a temporary global variables changed by using different keystrokes.

Corners do work, but one has to remember that lower corners are relative to indicator frame, not the timeline - see the video.

Unfortunately video upload does not seem to work on this forum :(

For the time being I put it on

antonio 2010.02.04 11:25 #30

After many tests have come to this result:

Value black and green = difference histograms

Value black great = current value of CCI

...but i have problems with the color of histograms.....
