Add another instrument to script

[siroki]

Hi,

Is it possible to add another instrument to a script?

Example: I run a 1-min NFLX strategy, but I want to know what the SPY is doing as well. If the SPY is up, then I only want to go long NFLX. If the SPY is down, i only want to go short.

Thanks

Hello siroki,

Yes, this is possible to do inside of a script. For example you may use the Add() method to add an instrument:

protected override void Initialize()
{
// Add an SPY 1 minute Bars object to the strategy
Add("SPY", PeriodType.Minute, 1);
}

Then to check the SPY instrument you may use the Opens, Highs, Lows, Closes values to check.

protected override void OnBarUpdate()
{
// OnBarUpdate() will be called on incoming tick events on all Bars objects added to the strategy
// We only want to process events on our primary Bars object (main instrument) (index = 0) which
// is set when adding the strategy to a chart
if (BarsInProgress != 0)
return;

// Closes[1] represents the SPY instrument and Rising check the value of 1 bar ago.
if ( Rising(Closes[1] )
EnterLong();
}
