Hi! I've problem with all my indicators values in strategy, when I looking to the chart all indicators that added from my strategy code have values that significally differs from values calculated by strategy.

For example there is a code for adding MA indicator on chart:

feedDescriptor = new TimePeriodAggregationFeedDescriptor (instrument, timeframe, offerSide, filter);
this.chart = context.openChart(feedDescriptor);

if ( ma3Timeframe == timeframe )
{ 
    IIndicator ma3 = indicators.getIndicator("MA");
    for (int i = 0; i < ma3.getIndicatorInfo().getNumberOfInputs(); i++)
    {
         InputParameterInfo inputParameterInfo = ma3.getInputParameterInfo(i);
         this.console.getOut ().println ("ma3 inputParameterInfo: " + inputParameterInfo.getName ());
         inputParameterInfo.setAppliedPrice (ma3Price);
    }
}
                                               
this.chart.addIndicator(ma3, new Object[] {ma3Period, ma3Type.ordinal ()}, 
new Color[]{Color.GREEN}, new DrawingStyle[]{DrawingStyle.LINE}, new int[]{1});

But when the strategy calculates the MA indicator values later in code, I've see the very significant difference in values between chart values and strategy calculations. There is the piece of code, that calculating the values:

long time = history.getBar(instrument, ma3Timeframe, offerSide, 0).getTime();
indicators.calculateIndicator(feedDescriptor, new OfferSide[] {offerSide}, "MA", new IIndicators.AppliedPrice[] {ma3Price}, new Object[] {ma3Period, ma3Type.ordinal ()}, 1, time, 0);

ma3Timeframe is the same as chart timeframe.

Waiting for your advice.

Did you check that the chart filter matches the one of your feed descriptor (i.e. chart.getFeedDescriptor().getFilter() compare with feedDescriptor.getFilter())? Note that with IContext.openChart, the Filter parameter gets taken not from the passed IFeedDescriptor, but rather the common platform settings (i.e. Tools > Preferences > Chart > Flats Filtration).

I've better results with my strategy, but on PERIOD.ONE_MINUTE Timeframe instrument: GBP/USD I got problems: Trendenvelopes indicator on chart and Trendenvelopes indicator calculations providing different values.

The Filter is the same for Chart and Strategy: NO_FILTER

The TrendEnvelopes indicator is added on chart with code:

this.chart.addIndicator(indicators.getIndicator("TRENDENVELOPES"), new Object[] {trendEnvelopesPeriod, trendEnvelopesDeviation});

Than I'm using the Trendenvelopes in calculations:

index= 1;
        long time = history.getBar(instrument, trendEnvelopesTimeframe, offerSide, 0).getTime();       
        double[][] envelopes = indicators.trendEnv(instrument, trendEnvelopesTimeframe, offerSide, trendEnvelopesPeriod, trendEnvelopesDeviation, filter, 2, time, 0);
                                          
        if ( !Double.isNaN(envelopes[0][index]) && price > envelopes[0][index] )
        {
            envelopesTrailValue = envelopes[0][index];
            trendEnvelopesSignal = +1;
        }
        else if ( !Double.isNaN(envelopes[1][index]) && price < envelopes[1][index] )
        {
            envelopesTrailValue = envelopes[1][index];
            trendEnvelopesSignal = -1;
        }
        else 
            trendEnvelopesSignal = 0;

And the problem is: I see on the chart that Trendenvelopes has only bottom(blue) line at 1.51000,
but in the code I've received that it is switched to top line(yellow), e.g. envelopes[1][index] has some value: 1.53000, but must be: envelopes[0][index] = 1.51000 and envelopes[1][index] = NaN.

Consider comparing your results the following way:
https://www.dukascopy.com/wiki/#Add_indicators_on_chart/Include_in_OHLC

OHLC shows the same as I see on chart, but indicator calculations are different from OHLC and chart values.

please provide your example strategy which uses the value putting in ohlc and chart feed comparison with the indicator feed.

Here is the strategy. The bug was on GBPUSD, M1 timeframe, TrendEnvelopes choosed, MA3, MA4, MA5 disabled, RSI disabled, Stoch disabled, ADX enabled

By strategy we mean full source code of the example strategy which replicates the case.

Here the full source code of the strategy(in attached)

Please provide an example strategy which replicates the case and does not contain any additional logic which is not related to the problem that you reported.

Hi! Check attached tiny version of the whole strategy, I've make it as much simple as possible, test it with default params on GBP/USD from 2013.03.05 to 2013.03.06 M1 timeframe.
Also check attached screenshot for the issue drawed by red ellipses. The OHLC shows completely different value form strategy calculations.

When I can get the answer for my previous post from support team???

TrendEnvelopes, when added on chart, gets recalculated on all currently available data
(see the description of the "recalculateAll" property for more info: https://www.dukascopy.com/wiki/#Indicato ... icatorInfo).
Unlike when it's called from your strategy. This means the calculation results will match only when you compare results calculated on the matching time intervals and the time interval used when calculating from strategy is much shorter.

How I can calculate indicator values on all chart bars in the strategy?

Why does it take so long for each answer?
I'd help you, but unfortunately I dont know.

You can calculate on a larger time interval by using 'from', 'to' or 'numberOfCandlesBefore'/'numberOfCandlesAfter' parameters of the indicator calculation methods

How I can get the number of all bars in chart?

See:
https://www.dukascopy.com/wiki/#Chart_Operations/Retrieve_drawable_coordinates

I mean how to get all bars that can be rendered on chart, not only visible bars.
