Using indicator parameters in Strategy

[nicbizz]

This follows from the Tutorial 2 sample strategy in the Help Guide (i.e. RSI with a Stop Loss and a Profit Target).

Our entry condition is this:

if (CrossAbove (RSI(RSIPeriod, RSISmooth), 20, 1))
{
EnterLong();
}

Instead of setting a new RSIPeriod for the strategy, I'd like to use the Period parameter from the RSI indicator, that is added during the Initialize() phase of the Strategy.

How do I got about referencing it?

Thanks!

Hello nicbizz,

Your strategy should control all the input parameters in this case.

You can use the same variable name for both places: 1) adding the indicator for visualization in initialize 2) evaluating indicator values in OnBarUpdate() for an order condition. This is what is shown in the example.

You can access the indicator "Period" value but there is no benefit to this. Since the user never has access to this indicator input when running the strategy, it will always be the default value for Period in the RSI indicator.

Hi Ryan,

THanks for the reply.

Perhaps this is not the best example to illustrate what I'm attempting to do.

Let's say I have a custom indicator called IndicatorX, which has a public property called PricePoint.

If I'd like to reference the value of PricePoint in my strategy, what is the correct syntax to do so?

In regular C#, I'd have to create an instance of IndicatorX .....

IndicatorX thisIndicator = new IndicatorX();

and then call the property using thisIndicator.PricePoint.

That is one way to do it.

Nicbizz,

Yes, that is how you would do it. Can see this sample for best practices on exposing non-plot value from another indicator:
