Tomasz,
I have to disagree with you on this.
IMHO in the vast majority of situations when you change indicator parameter
values you want to change them only for the selected instance - you do not
want those parameter values propagated everywhere else that the indicator
may be referenced (panes, windows, charts templates etc.) as it can easily
have unforseen effects (previous charts, commentaries, line studies now look
wrong). Finding and checking all other references to indicator would also be
a laborious task.
Parameters should enable a user to quickly apply and observe the effect of
different parameter values without editing code. The Parameter() function
was a *big* help with this but IMHO there are a few related implementation
issues which if addressed would provide a much improved all round facility:-
1. The "scope" of parameter value changes made via Parameters dialogue (too
wide at present as discussed above). This could easily be addressed by
adding a Scope radio button to Parameters dialogue e.g.
Current pane only [the default mode]
Current window (all panes)
All windows
2. Allow more than one copy of same custom indicator to be inserted into a
window. This is desirable to allow direct visual comparison of indicator
using different parameter values.
You mentioned making copy of indicators as workaround but this is really
much the same as hard coding indicators for different parameter values. We
just end up with MA3, MA5, MA6, MA8, ... CCI5...etc. and associated code
maintenance problems. Surely the whole point of parameters is make this sort
of thing unecessary?
