name of nested indicator

[Guest]

Hello

Let's say I have my own indicator something easy like SMA and called SMA. I apply this indicator to another indicator like SMA(EMA(5),5)[0].

Now the question is how from the OnBarUpdate of the SMA indicator access the name of the EMA. Here is an example, if I create string

string filename = Instrument.MasterInstrument.Name.ToString() + "_" + BarsPeriod.Id.ToString() + "_" + BarsPeriod.Value.ToString() + "_" + level.ToString() + ".txt";

I get something like "EURUSD_RANGE_16_7.txt", but I want to get

EURUSD_EMA_RANGE_16_7.txt, which means that I applied this indicator SMA not to Close prices but to EMA of Close prices.

Thank you.
