'+' - cannot convert enum prob.mq4 14 51

Going to write a servisdesk.


Have you seen the example ofObjectSetDouble in Help? It contains creation of Fibo, addition of levels and getting the values of the levels.

Hmm. it works for me.

Have you seen the example ofObjectSetDouble in the reference? It creates Fibo, adds levels and gets values of levels.

ObjectSetDouble(chart_ID,name,OBJPROP_LEVELVALUE,i,values[i]);

Sets the price.

If GET, it returns the level value, not the price.

Give me the code.
 

Dummy's hiccup, but enlighten me as to why the F1 button in the editor of the new 950 build does not work ?

THANK YOU !

Gets the price of Fibo anchor points:

Karputov Vladimir:

You get the price of the Fibo anchor points:

И? This is the price of 0% and 100%.

And you need to know the price of all levels.

 
Vasyl Nosal:

И? This is the price of 0% and 100%.

And you need to know the price of all levels.

As far as I know, it is calculated as a proportion through the 0 and 100 levels. There are no special functions for this.
 
Alexey Kozitsyn:

Yes. You have to calculate it manually and get the value of the levels via
ObjectGetDouble(ChartID(),name_fibo,OBJPROP_LEVELVALUE,i,temp_price)

I want the price, not the value of the level.
