Which is better to use Series or calling and Indicator within an indicator

[ballboy11]

For performance what is better to use

Example in order update

double dEMA = EMA(20)[0];

or use

private EMA dEMASeries;

in dataloaded
dEMASeries = EMA(20);

[eDanny]

private EMA dEMASeries;

in dataloaded
dEMASeries = EMA(20);

I believe your first example will create a new EMA(20) every time that code is hit.

For performance and data is the series better or just calling a value and dumping the value.

Once you create your own EMA, dEMASeries in the example, you can just access any data in the series for any bar, at any time.

OnBarUpdate()

double my_dEMA = sEMASeries[0]; //the EMA(20) of the current bar
