You need to programmatically request the price of the level. To do this, you must have "Fibo" object put on a chart and configured (all programmatically). It is not as easy as it may seem at first sight. However, Gods do not burn the pot. I once had to play with Fibo levels. And now I am working with processing of these levels. In general, if you want you can figure it out.

Here is an example of code to create a Fibo on a chart.

I had to make a subroutine to request the price of the level. Here it is (you can figure it out if you want to)

I.e., we should programmatically add the Fibonacci object to the Fibonacci fan and find out the price of the level only that way. Have I got it right?

In other words, we need to add the Fibonacci object to the Fibonacci vector and find out the price of the level only that way. Have I got it right?
You do not need to attach a standard Fibo object to the chart. You can simply programmatically calculate all Fibo levels considering the existing conditions,
enter them into variables or an array and compare the price with these levels calculated by yourself. That's exactly what I do... Although - all this is IMHO.

Can you please write a code example?

It's more complicated than the one Vladimir offered you... :))

I might like it better :) And besides, you don't want to have extra objects on the screen. There'll be plenty of them anyway and any unnecessary ones will just get in the way

Well, maybe I will like it better :) And besides, I don't want additional objects on the screen. There will be plenty of them there already, and any unnecessary ones will only hinder

My code is tightly bound to the data obtained by the Expert Advisor for which it was written. The function is only a part of necessary calculations and won't be of any practical value for you - only as a tutorial for self-comprehension. And that's with the rest of the code, where all the preliminary calculations are made.

If I made it universal, it would work slower, but I don't want that... :)

But you're welcome. This function was rewritten from Excel, where I checked its calculations. Two parameters are passed into it - the break of ZigZag (lower or upper, depending on type of position opened) and Price level 23.6 of the fib. The fib is not plotted as is generally accepted, but price is considered to have broken through the 23.6 fib and is above the consolidation level calculated in advance. The zero of the fib is placed on the break in ZZ, and a pose is opened on 23.6 (when it is broken). The remaining levels are written in the variables declared on the global level and subsequently entered into the array of the orders, from which levels are taken for any open position.

As for its usage, I would have to gut the entire Expert Advisor to understand it...

That's great, you gave me an idea.
 

Hi all! Please help me combine the following things. The result should be: two lines following the price, one lower than Ask by 20 pips..,

the other one is higher. Besides, I get a beep if price changes by 20 points per 1 tick.

All works fine separately. Thanks in advance!

1) The line below the Ask by 20 pips.

//+------------------------------------------------------------------+
//| expert initialization function |
//+------------------------------------------------------------------+
int start()
{
ObjectCreate("MyPriceLine", OBJ_HLINE, 0, 0, Ask-20*Point) ;
ObjectSet("MyPriceLine", OBJPROP_PRICE1, Ask-20*Point);
return(0);
}

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

2) The line is 20 pips above the Ask.

//+------------------------------------------------------------------+
//| expert initialization function |
//+------------------------------------------------------------------+
int start()
{
ObjectCreate("MyPriceLine", OBJ_HLINE, 0, 0, Ask+20*Point) ;
ObjectSet("MyPriceLine", OBJPROP_PRICE1, Ask+20*Point);
return(0);
}

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

3) Rate of price change over time.

Can you please explain why this code sometimes freezes in one place and you have to restart the terminal to resume it? 

int ticket,err;
         Alert("nachalo");
         ticket = OrderSend(Symbol (), OP_BUY, 1, Ask, 10,0,0, "dsgdsf", 0, 0, CLR_NONE);
         err = GetLastError();
         Alert (err);
         Alert("konec");
         OrderClose (ticket,1,Bid,5,CLR_NONE);
         Alert ("zakrito");

Seems to be boring already... It's elementary, Watson:

ObjectCreate("MyPriceLine", OBJ_HLINE, 0, 0, Ask-20*Point) ;

It's the name of a single line.

Hint: look up the name of the second line. Is it different from the first?

Yes, and why keep building an already-built facility? 

//+------------------------------------------------------------------+
//| expert initialization function |
//+------------------------------------------------------------------+
int start()
{
ObjectCreate("MyPriceLine", OBJ_HLINE, 0, 0, Ask+20*Point) ;
ObjectSet("MyPriceLine", OBJPROP_PRICE1, Ask+20*Point);
return(0);
}

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

Now look at the difference:

//+------------------------------------------------------------------+
//| expert initialization function |
//+------------------------------------------------------------------+
int start()
{
if (ObjectFind("MyPriceLine")<0) ObjectCreate("MyPriceLine", OBJ_HLINE, 0, 0, Ask+20*Point) ;
ObjectSet("MyPriceLine", OBJPROP_PRICE1, Ask+20*Point);
return(0);
}
