I'm not really sure what you mean? If you create an indicator you can call it directly in a strategy and you can also create your own library of custom functions/methods to call(user defined methods in the indicator lib).
To me its just a matter of time, it seems like anything can be done but its just a matter of waiting for Ninja to impliment it directly if you don'twant to roll your own work around in c sharp. 7.0 is sopposed to be out at the end of the year and sounds amazing, multi instrument stuff for plotting several series on the same chart in the same window, historic bid/ask..Seems like 7.0 is when it should really come of age.
