Accessing external data files in addition to the target stock

[MikeHersee]

Hi, a key element of my strategy development is having a target stock or index I want to trade, but also relying on data from a separate file or files that could - for example - contain socioeconomic data. That is, a separate file of data I will have maintained that has the exact same dates as all the stock or index files I'm interested in and the records are parallel day for day so it can be used for backtesting properly but which I will use as something that will influence, for example, thresholds that determine whether a signal indicates buy or sell. How do I access that data separate from the target stock with Ninjascript?

Any help much appreciated.

Hello MikeHersee,

Thank you for your post.

Something you could do is use a StreamReader to bring in data stored outside of NinjaTrader that you want to use for calculations in your script. Using a StreamReader will allow you to bring in data that is stored in text files and allow you to do manipulations with them.

See the help guide documentation below for an example and more information.
