In my strategy, I add the CCI indicator to the chart. The documentation describes well the methods on how the input and output parameters can be configured, but I could not find information on how you can configure the parameters presented on the "Levels" and "Advanced" tabs:



Please tell me how to do this using JForex-API.

Thanks in advance for your reply.
