Applying stat. indicators to spreads

["Tanoto Sau Ian" <sitanoto@xxxxxxxxxxxxxx>]

Hi,

I am trying to apply stat. indicators like RSI, momentum, etc to spread =
charts of spreads. However, that is not possible as I can only choose =
either data1 or data2, which are components of the spread, instead of =
the spread itself.

Do i have to rewrite all these indicators to work with spreads or are =
they just impossible to do so?

Tks, for all the help u guys are giving here.
