Adding indicator values to secondary series

[tkaboris]

Hi
I have a strategy that uses indicator as order entry and i am adding a secondary series and want to have a match entries. Secondary series indicator is _patsIndicatorA for anchored. I am getting an error cannot apply [] in the expressioni of type double. Is this the right way of calling indicator on secondary series?

private TDUPriceAction _patsIndicator;
private TDUPriceAction _patsIndicatorA;​

in configured state

 else if (State == State.Configure)
            {
                AddDataSeries(BarsPeriodType.Tick, 2000);
            }​

else if (State == State.DataLoaded)
            {
                ClearOutputWindow(); //Clears Output window every time strategy is enabled
                _patsIndicator = TDUPriceAction(Close, TDUPatsRules.Mack, false);


                _patsIndicatorA = TDUPriceAction(Close, TDUPatsRules.Mack, false);
                   ​

and in my entry logic i have

else if (All2Entries
                && (Position.MarketPosition == MarketPosition.Flat)
                && (_patsIndicator.SignalLong[0].ApproxCompare(2) == 0)                
                && !(_patsIndicator.SignalLong[0].ApproxCompare(1) == 0)

                && (_patsIndicatorA.SignalLong[1][0].ApproxCompare(2) == 0)                
                && !(_patsIndicatorA.SignalLong[1][0].ApproxCompare(1) == 0)    ​

Hello, thanks for writing in. We have an example here showing how to set up an indicator on a secondary series:

https://ninjatrader.com/support/helpGuides/nt8/NT%20HelpGuide%20English.html?using_a_secondary_series_as_an.htm

Your code is passing in the primary series in State.DataLoaded. The error you are getting means that _patsIndicator.SignalLong is not a series, but a double variable that is part of the _patsIndicator indicator class, so you will not be able to use it like a Series<double> object.

The link is broken, can you please double check the link? Also the indicator supports series.. So i wont be able to run strategy on both series entry when there is signal on both of the series?

[NinjaTrader_ChrisL]

Hi, the link is working for me. Here is the full link:

https://ninjatrader.com/support/helpGuides/nt8/NT%20HelpGuide%20English.html?using_a_secondary_series_as_an.htm

We have an example strategy built into the platform called "SampleMultiInstrument". This will show you how to submit orders to both series that the strategy is reading.

[tkaboris]

i wasnt able to find SampleMultiInstrument strategy only on github

https://github.com/beckerben/NinjaTrader/blob/master/%40SampleMultiInstrument.cs

I understand that I can call indicator with bars array when dealing with ninjatrader indicators. So with this custom indicator its not possible?
adx = ADX(14);
adx1 = ADX(BarsArray[1], 14);
if (adx[0] > 30 && adx1[0] > 30)

I added additional series to my strategy
I am printing Print("closes 1 1 "+Closes[1][1] + CurrentBars[1]); and in data window its bars 612, but it prints bar index 912. its not correct. How do i fix it? If i print Print("bars in progress" + BarsInProgress); i get barsinprogress0 always.. I just wanted to perform condition that secondary previous close is higher then open.

Also I am printing inside bar that i want to display on secondary series, how can i make sure it prints on secondary series and not on primary?

if(BarsInProgress == 1)
            {
            //here

            if ((Closes[1][1] > Opens[1][1]) && (Closes[1][0] < Closes[1][1]) && (Closes[1][0] > Opens[1][1]) && (Opens[1][0] < Closes[1][1]) && (Opens[1][0] > Opens[1][1])
             || (Closes[1][1] < Opens[1][1]) && (Closes[1][0] > Closes[1][1]) && (Closes[1][0] < Opens[1][1]) && (Opens[1][0] > Closes[1][1])  && (Opens[1][0] < Opens[1][1]))
                {
                    insidebar=true;
                    Draw.VerticalLine(this, @"Wide_Body1" + CurrentBars[0].ToString(), 0, Brushes.ForestGreen, DashStyleHelper.Dot, 1);
//                    Draw.ArrowDown(this, @"CongestionBox Arrow down_1 " + Convert.ToString(CurrentBars[0]), false, 0, (High[0] + 2) , Brushes.White);
                }
                else {
                    insidebar=false;
                }
                }​

Hi, your script is not doing something right. I can not tell what it is. You will need to reference the existing examples that I have already given you and debug your script by comparing what you are doing differently.

[tkaboris]

I am trying to print correct values but i cant with this logic. Something is wrong with referencing CurrentBars

if(BarsInProgress == 1)
{
Print("closes[1][1]" + Closes[1][1] + CurrentBars);

[NinjaTrader_ChrisL]

Hi, this code would not compile, it should be:

Print("Closes[1] [1] " + " - " + CurrentBars[0]);

Here is the documentation that can be accessed at any time if needed:
https://ninjatrader.com/support/help...tml?closes.htm //Closes

https://ninjatrader.com/support/helpGuides/nt8/NT%20HelpGuide%20English.html?currentbars.htm

I have included two print statements in both BarsInProgress==1 and in outside of it and only outside ofBarsInProgress prints out
bars in progress0
closes[1][1]135862594
so it prints from primary series.
I dont understand why BarsinProgress==1 is not executing. Do i need to initialize values for Closes[1][1]?


Print("bars in progress insied barsinprogess==1" + BarsInProgress); and Print("closes[1][1]" + Closes[1][1] + CurrentBars[0]);

if(BarsInProgress == 1)
            {
[B]Print("bars in progress insied barsinprogess==1" + BarsInProgress);
            Print("closes[1][1]" + Closes[1][1] + CurrentBars[0]);[/B]

            if ((Closes[1][1] > Opens[1][1]) && (Closes[1][0] < Closes[1][1]) && (Closes[1][0] > Opens[1][1]) && (Opens[1][0] < Closes[1][1]) && (Opens[1][0] > Opens[1][1])
             || (Closes[1][1] < Opens[1][1]) && (Closes[1][0] > Closes[1][1]) && (Closes[1][0] < Opens[1][1]) && (Opens[1][0] > Closes[1][1])  && (Opens[1][0] < Opens[1][1]))
                {
                    insidebar=true;
                    Draw.VerticalLine(this, @"Wide_Body1" + CurrentBars[0].ToString(), 0, Brushes.ForestGreen, DashStyleHelper.Dot, 1);
//                    Draw.ArrowDown(this, @"CongestionBox Arrow down_1 " + Convert.ToString(CurrentBars[0]), false, 0, (High[0] + 2) , Brushes.White);
                }
                else {
                    insidebar=false;
                }
            }
            #endregion
                    if (SystemPrint)

[B]Print("percent wick low [1] " + percentWick + " - " + CurrentBars);
                        Print("closes[1][1]" + Closes[1][1] + CurrentBars[0]);[/B]

                    }​

[tkaboris]

so stupid i had this line in my barupdate
if (BarsInProgress!=0) return;

[tkaboris]

Can you please help me to modify this line so it displays in secondary series and not in primaries??
Draw.VerticalLine(this, @"Wide_Body1" + CurrentBars[0].ToString(), 0, Brushes.ForestGreen, DashStyleHelper.Dot, 1);

P.S I wish you guys can hire someone to rewrite and or add a lot more to support files so they are actually make sense..

[NinjaTrader_ChrisL]

Hi, the secondary series that you add using "AddDataSeries" does not display on the chart, so drawing tools can only target the primary series. The indicator has a property "DrawOnPricePanel" If the indicator runs in its own panel and DrawOnPricePanel = false, the drawing tools will show up in the indicator panel. If DrawOnPricePanel is true, drawing tools will show up on the price panel.

[tkaboris]

hi, I am trying to call trendline values from secondary series. i was following an example but its not working. it shows error cant convert to double. Can you please help?
private TrendLines acnhoredTL;

if(BarsInProgress == 1)
anchoredTL = TrendLines(2,1, 0, false);

[NinjaTrader_ChrisL]

Hi, Please see the example in the TrendLines documentation first, it shows that it needs to be indexed:

https://ninjatrader.com/support/helpGuides/nt8/NT%20HelpGuide%20English.html?trend-lines.htm

double value = TrendLines(5, 4, 25, true)[0];
