Calling CandleStick pattern name from an indicator

[UltraNIX]

Hello,

I downloaded this CandleStickPatternAll indicator: https://ninjatraderecosystem.com/use...kpatternall-2/

and I tried calling patterns using this print: Print(Time[0] + " " + CandleStickPatternAll(Close, 4)[0]);

But it only returns timestamp and 1 (when pattern is present) and 0 (when pattern is absent).

How do I modify a code of an indicator, so it would return a pattern name instead of 1 or 0?

Hello UltraNIX,

Thank you for your post.

What I would recommend in this case is to create a Series<T> variable to hold a string and then update that variable with the bar pattern name or an empty string if there's no particular pattern for a bar.

Here's an example of exposing a variable that's not a plot's value:

I'd keep the existing 0/1 functionality but just add the Series<T> to access the names from another script.

Please let us know if we may be of further assistance to you.

I got error message:
'NinjaTrader.NinjaScript.Indicators.CandleStickPat ternAll.CSPN1' is inaccessible due to its protection level

I tried to use this print: Print(Time[0] + " " + CandleStickPatternAll(Close, 4).CSPN1[0]);

Where CSPN1[0] is a series from CandleStickPatternAll. Indicator compiled fine, but strategy gave an error.

Hello UltraNIX,

Thank you for your reply.

Would you be able to post your current modified version of the code so I may test on my end? You can export it from Tools > Export > NinjaScript Add-on. Do not check the box to export as a compiled assembly or I will not be able to review the code. Please attach the resulting .Zip file to your reply.

Thanks in advance; I look forward to assisting you further.

Here you go. I added "//" before Print in strategy for it to compile.

Hello UltraNIX,

Thank you for your reply.

You haven't got an exposed property for your Series<T> in the indicator, so the strategy can't access it.

You need to add something like this to the Properties region:

[Browsable(false)]
[XmlIgnore]
public Series<string> cSPN1
{
get { return CSPN1; } // Allows our public cSPN1 Series<string> to access and expose our interal CSPN1 Series<string>
}

You could then access this in the strategy with:

Print(Time[0] + " " + CandleStickPatternAll(Close, 4).cSPN1[0]);

I've made the c in the exposed series lowercase to differentiate it from your internal CSPN1 series.

Please let us know if we may be of further assistance to you.

Thanks, works like a charm. By the way, another candlestick-related question. How to make 'approximate estimation', like if high is within 3% range from previous high, then X, if not, then Y. I just want basic calculation process, which I could adapt to my own use.

Hello UltraNIX,

The 'Select pattern' is a public property that does not change that can be returned from the script.

Print(CandleStickPatternAll(Close, 4).Pattern);


To find a percent of the high you can multiply the high by .03.

High[0] * .03

To get the high of the previous bar, use 1 as the barsAgo index.

High[1] > High[0] - (High[0] * .03)
