how to use variable

[n1144n]

Hi,

I am trying to learn Ninja script.
I need some help with this simple strategy I did in Strategy Builder.

It is just a simple strategy that I want to have a variable control how many consecutive Renko bars in the same direction appear before I enter a trade.

All the bars have to be in the same direction. up or down.

how do I replace the '15' with a variable from 1 to 15?


// Condition set 1
if (DM(DMperiod).DiMinus[0] < 1
&& DM(DMperiod).DiMinus[15] < 1)
{
EnterLong(Contracts, "Long 1");
}

Thanks, n1144n

Hello n1144n

Thanks for your post.

I may be misunderstanding your question, if so, please ask in another way.

I think you are asking how, directly in Ninjascript, to replace 15 with a variable that you can set from the user panel when applying the strategy.

You could need to create a public variable, call, for example, "Lookback" in the region properties. Here is an example:

[Range(1, int.MaxValue), NinjaScriptProperty]
[Display(ResourceType = typeof(Custom.Resource), Name = "Lookback", GroupName = "NinjaScriptParameters", Order = 1)]
public int Lookback
{ get; set; }

In State.SetDefaults you would need to set the default for the property, for example: Lookback = 5; // default to 5 bars lookback.

Then in OnBarUpdate() you would replace 15 with Lookback, for example:

&& DM(DMperiod).DiMinus[Lookback] < 1)
