even flipping the 14 and 3 around gives me nothing but the default 5,3,3

please provide full example strategy, please describe more precisely what results you expect and what they actually are.

Please only confirm that you SHOULD or SHOULD NOT be able to (from any strategy you have there) obtain 14,3,5 (second screen shot shows I only get the defaults) by issuing the above optional input settings (first screen shot) on your own "stoch" indicator on API v2.7.5.
I have solved this at my end by trying:
i.setOptInputParameter(0, 14);
i.setOptInputParameter(1, 3);
i.setOptInputParameter(2, 0);
i.setOptInputParameter(3, 5);
i.setOptInputParameter(4, 0);
ct.add(i)
then trying:
ct.add(i)
i.setOptInputParameter(0, 14);
i.setOptInputParameter(1, 3);
i.setOptInputParameter(2, 0);
i.setOptInputParameter(3, 5);
i.setOptInputParameter(4, 0);
and eventually winning with:
ct.add(i, new Object[]{14,3,0,5,0}); <------

Without full example strategy we can't precisely imply what you mean.

Just in case anyone reads this thread and needs conclusion, the issue above is simply that
i.setOptInputParameter() is not for calling by us but it's called by the indicator subsystem.
so using IChart add(indicator, array) e.g. ct.add(i, new Object[]{14,3,0,5,0}) is the way you
add indicators and set their optional parameters.
If you try to call i.setOptInputParameter() then IChart add(indicator, array)
the parameters are overridden by the ones provided in the array.
If you try to call i.setOptInputParameter() then IChart add(indicator) what
you set is overridden by the defaults (i.e. ignored).
