There was a problem with getting the indicator parameters. I do the following:
I add the indicator parameter to the global scope of the expert Advisor
input double inpStepSize = 2; // Step size
I get the indicator handle
Handle = iCustom(m_symbol.Name(),_Period,"chart_1",inpStepSize);
As a result, when connecting the expert Advisor, I have the necessary parameter in the “Input parameters” tab. But, when you change its value, the picture of the graph does not change. The indicator parameter that I change in the expert Advisor – the old one remains in the indicator.
How can I make it possible to change the indicator value on the expert Advisor’s “Input parameters” tab?
