how do I choose a label I selected?

Hello,

in my indicator I have several labels - how I can find out a label I have selected??

Right click anywhere on the chart and select Objects List. Make a guess at the one you think it and click "Show" or "Edit".

sorry - i meant in MQL 4

If you know the name, use ObjectGet(). If you want every object, try this:

for( int i=0; i<ObjectsTotal(); i++)
{
string name = ObjectName(i);
}
