Discussion of article "A Universal Oscillator with a GUI" - page 2

Good indicator, thanks for that.
While I was try to use the indicator  that uses a Divergence indicator which uses this indicator for getting oscillator data I came across these lines of indicator handles

      

m_handle=iATR(Symbol(),Period(),ma_period);
m_handle=iBearsPower(Symbol(),Period(),ma_period);
m_handle=iDeMarker(Symbol(),Period(),ma_period);

These lines creates handles for the selected oscillator and they works fine, but my concern is the hand-coded Symbol() and Period() functions. I plan to use the indicator on a Multi-symbol EA, so that means that I will create indicator handles of other symbols and periods from a single chart. My concern Is these hand-coded Symbol() and Period() functions that I think will give me the handle of current chart instead of handle of symbol and period that entered as arguments on the iCustom functions that called it.
My expectation was these lines would look like this:

pSymbol // parameter symbol variable from iCustom
pPeriod // parameter period variable from iCustom
m_handle=iATR(pSymbol,pPeriod,ma_period);
m_handle=iBearsPower(pSymbol,pPeriod,ma_period);
m_handle=iDeMarker(pSymbol,pPeriod,ma_period);

Can you help me clarify this doubt. How to use the indicator on a Multi-Symbol EA
