Global Variables?

[spiralhead]

Hello I am in a situation where I would like to share data between two of my indicators. For example I would like to use the value returned by indicator A to derive the value of indicator B. Is there a way to do this?

In other words is there a centralized, thread-safe data store that can be written to/read from anywhere?

Hello spiralhead,

Global variables in C# can be used but are not supported. I'm not sure you will need them in this case. You can easily access plots from other indicators. If the value is not a plot, we have a sample available for accessing these values from other indicators:

Hello. Thank you. Is there an example of how to access a plot as well?

[NinjaTrader_RyanM1]

Plots can be accessed by calling the indicator directly. The line below gets the most recent MACD average plot.

MACD(12, 26, 9).Avg[0]

The easiest way to get syntax for multi plot indicators is using the strategy wizard. You can select which plot you want from the GUI and then click view code option.

The alternative approach to the sample indicator Ryan is pointing to is to use the UserDefinedMethods. You find the templetes both in "Strategy" and "Indicator". Don't know if that is thread save.

Ninjatrader,
I need to know if UserDefinedMethods and Startegies are thread safe.

I'm running multiple strategies each of which call the same methods inside UserDefinedMethods.cs. In the methods, the below functions are called which are ment to refer to the the calling strategy.

Will each strategy & method combo be in it's own seperate thread? Or will the UserDefinedMethods pass results back to a 'wrong' strategy?

functions used ...

Position.MarketPosition == MarketPosition.Short
Position.AvgPrice
Performance.AllTrades.TradesPerformance.Currency.A vgProfit
DefaultQuantity
and so on

Hi Sajosh,

Yes, it is fine to use these properties in the user defined methods file. They will only relate to the strategy instance that calls them.
