Looking for a tutorial on how to manipulate indicators to create a new indicator

[forrestang]

Quick question. I uninstalled my ninja when I was looking to fix that problem with the error above. I also deleted the files in program files, and copied the ninja folder in "my documents." I did not create a backup before doing this.

Can I restore my tic data with the ninja folder I saved off from the "my documents" folder? Is there a folder in there that contains that data? I don't think ninja supports that in a way like some other platforms correct?

Looking for an explanation on List Variables, there doesn't seem to be anything in the ninja documentation?

[NinjaTrader_Bertrand]

Arrays and Lists would be more general C# and therefore outside of the scope we can support here, but MSDN / Google would offer lots of input on those.

For the folder you saved, look under NinjaTrader7 > DB > this would contain your stored historical data (tick, min, day).

Can I just copy the "db" folder over?

[NinjaTrader_Bertrand]

Yes, that should work, close NT7 before doing this step.

How would I go about creating a data series within one indicator that I could reference from another indicator.

Say I have an indicator that calculates the value of something, and I then want to put that into a series.... so that from another indicator I can reference these values.

[NinjaTrader_Bertrand]

You would need to store values in a custom series and then expose this series for external access (plots would be exposed per default, but not regular dataseries objects) - here's how it works:

I am a bit confused. I installed the "SampleBoolSeries" file, and attempted to get access to the BoolSeries created in the file, "SampleBoolSeries."

I created a random study, to print the value of the dataseries(bullIndication) that is created in the sample file as I thought the purpose was to have the information in that DataSeries available to any study?

I tried to get access to that file with:

Print(SampleBoolSeries().bullIndication[0]);

And then I get the following error in the picture.

[NinjaTrader_Bertrand]

Yes, this will not work, you would need to access the public property, so the capitalized Bull / Bear indication.

Ok that worked, thank you sir!

I've gotten most everything I need and my script is working close to the way I want, but now I'm having a "DrawText" Problem.

http://www.ninjatrader.com/support/helpGuides/nt7/index.html?intseries_class.htm

Here are some arrows I painted on the chart, along with some text I wanted to print under these particular arrows. You can see it will only print on one arrow and not ALL of them. I have the DrawText in the same location of my code as the arrows.

I thought it was because they both had the same tag, but I paused one of them, and still got the same issue.

How would I get this to print the text for each one?

Here is the code snipet in case the pic is unclear:

			//1a_a Trade
			if(ERG_Trade().Ltsx[0] == 1 && ERG_Str1().HISTSlope[0] == 1 && ERG_Trade().HIST[0] >= 10 )
			{
				if(ERG_Trade().HISTSlope[1] == 1 && ERG_Trade().HISTSlope[2] == 1 && ERG_Trade().HISTSlope[3] == -1)
				{	
				DrawArrowUp("arrow"+CurrentBar.ToString(), true, Time[0], Low[0]-12*TickSize, Color.Green);
				DrawText("text"+CurrentBar.ToString(), Open.ToString(), 0, Low[0]-30*TickSize, Color.Black);
				DrawText("text","1a_a", 0, Low[0]-38*TickSize, Color.Black);
							
				}
			}

I've gotten most everything I need and my script is working close to the way I want, but now I'm having a "DrawText" Problem.......

I got it working.

I have another question. I've generating a bunch of entry arrows/signals. The plan is to eventually get this into a strategy.

How would I go about generating the opposing sell signal for each of my entries based on some criteria I have? Is there a functionality in ninja that makes this easy to do?

Here is an example of the code I use to generate one of the signals.

[NinjaTrader_Bertrand]

PPF's are a wonderful thing - sorry I'm not sure I follow exactly what you look for - wouldn't your sell signal then be tied to a custom condition programmed into the script as well?

Generally you can tag entry & exitsignal together via the EntrySignal / FromEntrySignal paramters provided in the Entry() methods.

Well, say for example I already have ALL the entry signals coded, which I do. So each time a possible trade shows up, it plots the corresponding arrow at the proper time. So all my entry signals are right where I want them.


Looks like I forgot to attach ONE OF the code snippet used to generate an entry:

//1a_A Trade
			
			if(ERG_Trade().Ltsx[0] == 1 && ERG_Str1().HISTSlope[0] == 1 && ERG_Trade().HIST[0] >= 10 )
			{
				if(ERG_Trade().HISTSlope[1] == 1 && ERG_Trade().HISTSlope[2] == 1 && ERG_Trade().HISTSlope[3] == -1)
				{	
				DrawArrowUp("arrow"+CurrentBar, true, 0, Low[0]-12*TickSize, Color.Green);
				DrawText("text0"+CurrentBar, ""+Open.ToString(), 0, Low[0]-30*TickSize, Color.Black);
				DrawText("text1"+CurrentBar ,"1a_A", 0, Low[0]-38*TickSize, Color.Black);
				inTrade = true;			
				}
				
			}
