Good afternoon!

There is a problem with the indicator software, the author claims that the indicator is working, but in fact the graph is not displayed - what is the problem?

The problem is in these lines

   int i, counted_bars = IndicatorCounted();
//---- check for possible errors
   if(counted_bars < 0) 
       return(-1);
//---- last counted bar will be recounted
   if(counted_bars > 0) 
       counted_bars--; 
   int limit = Bars - counted_bars;
The new compiler gives an error when executing, but when compiling it's ok. Have the author run it in the debugger and see the problem immediately.

There is no problem, everything works. It's enough to restore the buffer description

//---- buffers
double [];
double Spread[];
double FastEMA[];
double SlowEMA[];

The problem is with the default tool. Most likely there is no GOLD tool, if you put in another tool it's OK


 
What does the yellow signal broadcasting icon in the Metatrader mean? That the signal is temporarily not broadcasting? And why some signals that I can see now in the terminal are not currently listed on mql5.com?
 
Vinin:

The problem is with the default tool. Most likely there is no GOLD tool, if you put another tool in, everything is fine.



You see the thing is, I really care about the GOLD tool, how can I hook it up to the terminal?

Either it is there or it is not. It all depends on the brokerage company. Whether it provides such a tool or not.

Thank you, the picture is clear!

 

Good afternoon. I'm learning how to screw indicators into an EA but so far not very successful.

1 - When I run the EA through a tester only when I stop it the indicator labels appear.

2 - I don't understand what are the conditions and how they are written.

I want to ask my EA to trade based on indicator, I just need to know how to attach indicator to my EA.

Based on the arrow indicator which shows up or down BS_Living Now ver #1.mq4 https://www.mql5.com/ru/code/11014#50910

If you write a simple script which creates an object of type OBJ_ARROW_RIGHT_PRICE and then deletes it, the object is not deleted. Moreover, the ObjectType command suddenly turns out that the created object is not of type OBJ_ARROW_RIGHT_PRICE (==36), but ==22 i.e. a simple "arrow up" !!! Am I the only one who has this or does everyone have this?

There were already opinions of "experts" on this issue: like read the help, or not enough memory :) .

Memory is enough.

It appears that the ObjectCreate command draws an object of the OBJ_ARROW_RIGHT_PRICE type , which cannot be removed by the ObjectsDeleteAll(0,OBJ_ARROW_RIGHT_PRICE) command, but can be removed by the ObjectsDeleteAll(0,22) command, as if we had not the right price tag but an "up arrow". Whose fault ?

}

To delete an object of type OBJ_ARROW_RIGHT_PRICE, use command ObjectsDeleteAll(0,OBJ_ARROW), making sure to specify its subwindow.

p.s. An object of type OBJ_ARROW is "arrow" any, not just "up arrow". ObjectCreate(...OBJ_ARROW...) creates an "up arrow" immediately. So why isn't this in the help?

To delete an object of type OBJ_ARROW_RIGHT_PRICE use command ObjectsDeleteAll(0,OBJ_ARROW), with mandatory indication of subwindow.

Write in this thread. At least the developers are there.
