Hi
How can I show variables from a indicator I've downloaded and then used as a custom indicator in Strategy Builder. I am attaching a Keltner channel to my charts and wish to optimise its inputs. If I have to type in some code to do it well so be it but not sure where to start.
Thanks

When you import the custom indicator into the strategy builder it adds all variables separated by commas in the custom field. (see molanis.com/support/manuals)
So you may see something like 10,3,4 etc Every number is an input for the indicator. You need to know what they do.
In the strategy builder create a variable, let call it period, then go to the TA icon that has the custom indicator, and replace a number with the variable.
You will have something like
period,3,4
You can also do this directly in the metaeditor if you are comfortable with changing the code

The TA icon shows all the variables in the custom field. The indicator I'm using has at least 5 variables. Does this mean in need to open 5 TA blocks and set each input as a variable?

You have to make the change in all the icons that use the custom indicator. For example, A simple ma strategy uses 2 TA icons, one to buy and one to sell. If you use a custom ma indicator, you will need to change it in both TAs otherwise optimization will one work for one side (buy or sell)
