To write indicator correctly, I must know not only exact data contained in "Input" but also exact source of these data. For example, is "Input" actually equal to "Open", "Close" or something else.
I have searched all around product documentation but cannot find any variable or function to rely on. Strange enough, DataSeries does not support any text field to identify series name or the like.
The only crazy idea i have so far, is consequently comparing "Input" point by point with every other series until unique coincedence is discovered. But it is incredibly ridiculous!
