Multi-Series Scripting Overview

NinjaScript supports multiple time frames and instruments in a single script. This is possible because you can add additional Bars objects to indicators or strategies, in addition to the primary Bars object to which they are applied. A Bars object represents all of the bars of data on a chart. For example, if you had a MSFT 1 minute chart with 200 bars on it, the 200 bars represent one Bars object. In addition to adding Bars objects for reference or for use with indicator methods, you can execute trades across all the different instruments in a script. There is extreme flexibility in the NinjaScript model that NinjaTrader uses for multiple-bars scripts, so it is very important that you understand how it all works before you incorporate additional Bars objects in a script. An important fact to understand is that NinjaScript is truly event driven; every Bars object in a script will call the OnBarUpdate() method. The significance of this will become evident throughout this page.


Note:  If using OnMarketData(), a subscription will be created on all bars series added in your indicator or strategy strategy (even if the instrument is the same).  The market data subscription behavior occurs both in real-time and during TickReplay historical


It is also important that you understand the following method and properties:







Note:  As we move through this section, the term "Primary Bars" will be used and for the purpose of clarification, this will always refer to the first Bars object loaded into a script. For example, if you apply a script on MSFT 1 minute chart, the primary Bars would be MSFT 1 minute data set.
