Working on two products (stocks) at the same time

[marcusplexus]

Hi, I want to perform backtesting using the notion of relative
strength. I would compare price action for a given stock to the "price" action of a given index (e.g. Nasdaq).

Visually, I would set up a chart with Panel-1 displaying stock price action and Panel-2 would display the Index price action.

I what manner can I tell my ninjascript that I wish to manipulate the stock price in certain cases, then maninpulate the index price in others?

If I wanted to code the following pseudo-code:

IF Stock_Price_Last_Close > EMA(15)[0]
AND Index_Price_Last_Close > EMA(15)[0]

What would replace Stock_Price_Last_Close and Index_Price_Last_Close ?

Hello marcusplexus,

Thanks for your note.

The Closes series will contain all of the added data series. You will need to add the additional data series to the script using the Add() function, separate from adding them to the chart's lower panel as well.

For example, if the primary data series is GOOG and the secondary is ^NDX (Nasdaq 100):

Closes[0] will contain the GOOG Close data series. Closes[0][0] will be current bar of GOOG.
Closes[1] will contain the ^NDX Close data series. Closes[1][0] will be the current bar of ^NDX.

Please let me know if I can be of any other assistance.
