Operations with indicator values

[guillembm]

Hi,

I would like to make operations with the values of indicators but it seem that it's not possible.

For an operations like

Dif = StdDev(14) - StdDev(7);

I get the error "Operator "-" cannot be applied to operands of type Ninjatrader.Indicator.RSI" on compiling

How to retrieve the value of indicators?

guillembm, is Dif a double value here?

For the indicators they return a dataseries, so try accessing a double value from them by accessing via an index value : Dif = StdDev(14)[0] - StdDev(7)[0];
