hi.

in my strategy, l create a bbands :

       AppliedPrice appliedPrice = AppliedPrice.CLOSE;
      
        // Incrémentation des Indicateurs
        double Kama = indicators.kama(instrument, Period.FIFTEEN_MINS,OfferSide.ASK, appliedPrice, 20, 2,30,5);
        
        // Bande de Bollinger
        MaType maType = MaType.SMA;
        double BB[] = indicators.bbands(instrument, Period.FOUR_HOURS, OfferSide.ASK, appliedPrice, 20, 2, 2, maType, 1);

(sorry for my bad english, i speak french)

but, when i check the vallue of de BB[1] , its give me a value of Bollinger Bands with a timeperiod 6 or 7 (but not the data of a bbands with timeperiod of 20 lol)
i manually adds bbands indicators on the chart(Four Hours) with the setting 20,2,2,1 with MaType SMA and i really dont have the same value

i check the value of BB[1] with that :

        for (IChart chart : this.context.getCharts(instrument)) {
            chart.setCommentFont(font);
            chart.setCommentColor(Color.GRAY);
            chart.comment("Bande de Bollinger : " + BB[1]);
        }

i try with indicators.sma(...) and i have a the same problem with the data

* I have the right data for the Kama

Ok!
Thanks for fast reply!

Reply me if what i say is wrong plz

If i understand what did you say, i must plot indicators Kama on chart and add this in OHLC
and i suppose to make a function "Plot on newly opened chart" (for the Bollinger Bands in Four Hours) and add it in the OHLC too?


In the final result, i have 2 chart opened and 1 indicators each chart, and the code will working?
I suppose i dont delete this part of code

        double Kama = indicators.kama(instrument, Period.FIFTEEN_MINS,OfferSide.BID, appliedPrice, 20, 2,30,5);
        
        // Bande de Bollinger
        MaType maType = MaType.SMA;
        double BB[] = indicators.bbands(instrument, Period.FOUR_HOURS, OfferSide.BID, appliedPrice, 20, 2, 2, maType, 1);

Normally if i add indicators on chart, it is just a visual utility? Because if i dont plot indicators on each chart, i just want know if i can only create function to open a four hours chart and it's working?

Sorry, i'm just a beginner for creating strategy lol!

Thanks you

This our suggestion for more convenient chart-to-strategy indicator value comparison. Which example to use is up to you - whichever helps you understand where the problem lies.

AH OK!!

Forget the last post lol!

I understand. I had found my problem, it's juste a bad filter choice.

Thanks.
