Hello Support,

I want traslate from C# this code:

Only for Range Bars (Parameter), Calculate signals on bar close or Tick.

Signal Buy:

if (High[0] > ParabolicSAR(Open, 0.02, 0.2, 0.02)[1]
&& ParabolicSAR(Open, 0.02, 0.2, 0.02)[1] > ParabolicSAR(Open, 0.02, 0.2, 0.02)[0]
&& ParabolicSAR(Open, 0.02, 0.2, 0.02)[1] < High[0]
&& High[1] < Bollinger(2,14).Upper[2]) )
{

DrawArrowUp("My up arrow" + CurrentBar, false, 0, Low[0], Color.Cyan);
Alert("Bull Alert", Priority.High, "Bull Breakout", "Alert2.wav", 100000, Color.White, Color.Blue);

}


Signal Sell:

if (Low[0] < ParabolicSAR(Open, 0.02, 0.2, 0.02)[1]
&& ParabolicSAR(Open, 0.02, 0.2, 0.02)[1] < ParabolicSAR(Open, 0.02, 0.2, 0.02)[0]
&& ParabolicSAR(Open, 0.02, 0.2, 0.02)[1] > Low[0]
&& Low[1] > Bollinger(2,14).Lower[2]) )
{
DrawArrowDown("My down arrow" + CurrentBar, false, 0, High[0], Color.Red);
Alert("Bull Alert", Priority.High, "Bull Breakout", "Alert2.wav", 100000, Color.White, Color.Blue);
}

Hello,

Is there any example to see strategies range bars that use indicators Parabolic Sar or Bollinger Bands.

My knowledge of English is limited and I'm a little confused.


Regards.

See:
https://www.dukascopy.com/wiki/#Indicator_Calculation/Universal_price_feed
To find out values necessary for SAR or BBANDS, run the following example:
https://www.dukascopy.com/wiki/#Indicator_metadata/Retrieve_indicator_metadata

Example how to get a previous bar awesome values using 3 special bband methods and one universal calculateIndicator method.
First we need to initialize necessary fields:

private static int timePeriod = 14;
private static double nbDevDn = 2;
private static double nbDevUp = 2;
MaType maType = MaType.EMA;


Object[] bbandsUniversal = indicators.calculateIndicator(feedDescriptor, new OfferSide[] {OfferSide.BID}, "BBANDS",
new IIndicators.AppliedPrice[] {IIndicators.AppliedPrice.CLOSE},
new Object[]{timePeriod, nbDevUp, nbDevDn, MaType.EMA.ordinal()}, 1);



The sentence MaType maType = MaType.EMA show error, why??

It is not clear what you mean, please provide full example strategy.

I try get last bar bollinger bands indicator values (Upper Band, Middle Band, Lower Band) using universal method, but this not compile:

Object[] bbandsUniversal = indicators.calculateIndicator(instrument, timePeriod, new OfferSide[] {OfferSide.BID}, "BBANDS",
new IIndicators.AppliedPrice[] {IIndicators.AppliedPrice.CLOSE},
new Object[]{timePeriod, nbDevUp, nbDevDn, MaType.EMA.ordinal()}, 1);

You need to add an import:

import com.dukascopy.api.IIndicators.MaType;

In order to avoid such compile-time errors, consider using an IDE, For example Eclipse or NetBeans.
