Is adding a secondary timeseries as meta criteria possible?

[MickeyHR]

My idea is to produce a set of criterias where the general market conditions (say criteria of S&P) would used as a meta criteria and checked first and if that is passed then calculate the results of the actually analyzed instrument (like AAPL).

A rough example of my thinking

if
50 day SMA of S&P is rising
calculate 10 day SMA AAPL + ATR
else if
50 day SMA of S&P is sinking
calculate 10 day SMA AAPL - ATR
else
calculate 10 day SMA AAPL

My main question is: If possible how should I formulate the parts:
50 day SMA of S&P is rising
and
50 day SMA of S&P is sinking

should I perhaps use the DataSeries Class?

A practical code snippet would be much appreciated!

Hi Mickey, you would use the Add() method to add the needed instruments / series to your scripts in the Initialize() section. A practical working code example showing this is preinstalled with NinjaTrader and it's called 'SampleMultiInstrument'.
