I'm stuck on getting market data

[rsteckly]

Hi All,

I'm trying to develop a very basic add on to ninjatrader. This add on would show me a screen and display 4 prices on it (from 4 instruments). It would then compare the price changes between these instruments and alert me when some of those prices have changed.

Eventually, I'd like an order button that would execute a spread but let's not get crazy.

ALL I would like to do right now is to get the prices from the market data feed and display them in a window.

I can't seem to find any documentation on how to retrieve data from the feed. Does anyone have sample code or can point me to a sample project that shows the data being updated?

Thanks!

Hello rsteckly,

Thanks for opening the thread.

The AddOnFramework sample provided in our help guide has a working implementation for subscribing to MarketData and displaying the results in the AddOn window. The relevant code can be found in the Data Access regions of the sample. The sample subscribes to this data within the Instrument class of the InstrumentProvider interface.

This sample can be found in our help guide here: https://ninjatrader.com/support/help...t_overview.htm

Some documentation on the components used in the sample to handle subscribing to MarketData can be found below:

InstrumentProvider - https://ninjatrader.com/support/help..._interface.htm

MarketData - https://ninjatrader.com/support/help...marketdata.htm

I currently do not have a smaller sample that I could share to demonstrate.

Please let me know if I can be of further assistance.
