location of objects in CustomSymbol (MT5)

 
Hello, greetings again.
testing the mt5 tools, I created a custom symbol and the formula that associated it was EURUSD / 10000
In this way I get a symbol whose values have many decimals (8 decimals)
The problem with this is that when I want to edit the price of the objects, like a horizontal line, a precise value, I do not take the price I associate, but I take a "rounded" price to 5 decimal places. (If I move it manually, if it is "located" where I release it (a location with 8 digits)), but if I observe the properties that theoretically have that object, I associate again a position rounded to 5 digits.

How do I achieve my goal of being able to locate the object at a precise value?

Hello, can someone help me with this?
will it be scaled to support?
Thanks!
