Hi all,

I'm struggling to rewrite the defaults Bollinger Band SE LE signal. I want enter and exit based on market order. I tried something like below. I changed private IOrderMarket m_BBandLE; AND m_BBandLE = OrderCreator.MarketNextBar (new SOrderParameters(Contracts.Default, "BBandLE", EOrderAction.Buy)); as you see below. I'm getting getting an error.

using System;

namespace PowerLanguage.Strategy
{
public class Bollinger_Bands_LE : SignalObject
{
private IOrderMarket m_BBandLE;

public Bollinger_Bands_LE(object ctx) :
base(ctx)
{
Length = 20;
NumDevsDn = 2;
}

[Input]
public int Length { get; set; }

[Input]
public double NumDevsDn { get; set; }

private VariableSeries<double> m_LowerBand;

protected override void Create()
{
m_LowerBand = new VariableSeries<Double>(this);
m_BBandLE = OrderCreator.Stop(new SOrderParameters(Contracts.Default, "BBandLE", EOrderAction.Buy));
}

protected override void CalcBar()
{
m_LowerBand.Value = Bars.Close.BollingerBandCustom(Length, -NumDevsDn);
if (Bars.CurrentBar > 1 && Bars.Close.CrossesOver(m_LowerBand, ExecInfo.MaxBarsBack))
m_BBandLE.Send(m_LowerBand.Value);
}
}
}

This is the error I'm getting

hoang101483,

take a look at the MC.NET programming guide. Besides explaining how to operate the different order types, you can likely use the code snippet in section 2.2. and adapt it to your needs.

ABCTG,

Thanks for for the link. I tried to modify it but still getting the same error. Something is wrong with this part. Can you help me?

m_LowerBand.Value = Bars.Close.BollingerBandCustom(Length, -NumDevsDn);
if (Bars.CurrentBar > 1 && Bars.Close.CrossesOver(m_LowerBand, ExecInfo.MaxBarsBack))
m_BBandLE.Send(m_LowerBand.Value);

It is saying can not double to init.... Can you tell me how to fix it?

hoang101483,

you are trying to send the value of the bollinger band as quantity of a market order. You can for example issue the order without specifying a quantity and have MC use the default one as specified in your workspace.

Can you just tell me how to fix it. I'm not very good with coding. I tried this. But failed.

m_HigherBand.Value = Bars.Close.BollingerBandCustom(Length, NumDevsUp);
if ( Bars.Close.CrossesUnder(m_HigherBand, ExecInfo.MaxBarsBack))
m_BBandSE.Send(m_HigherBand.Value);

This is what I have currently. which line do I need to fix?

using System;

namespace PowerLanguage.Strategy
{
public class Bollinger_Bands_LE : SignalObject
{
private IOrderMarket m_BBandLE;

public Bollinger_Bands_LE(object ctx) :
base(ctx)
{
Length = 10;
NumDevsDn = 1;
}

[Input]
public int Length { get; set; }

[Input]
public double NumDevsDn { get; set; }

private VariableSeries<double> m_LowerBand;

protected override void Create()
{
m_LowerBand = new VariableSeries<Double>(this);
m_BBandLE = OrderCreator.MarketNextBar(new SOrderParameters(Contracts.Default, "BBandLE", EOrderAction.Buy));
}

protected override void CalcBar()
{
m_LowerBand.Value = Bars.Close.BollingerBandCustom(Length, -NumDevsDn);
if (Bars.CurrentBar > 1 && Bars.Close.CrossesOver(m_LowerBand, ExecInfo.MaxBarsBack))
m_BBandLE.Send(m_LowerBand.Value);
}
}
}

ABCTG,

Please Please help me. tI would a lot to me if I can automate this strategy

Pump. Would someone please help me !
