Help to code a simple strategy

[7Maxx]

Can somebody help me and write a simple code to backtest the TSSupertrend indicator?

http://ninjatrader.com/support/forum/showpost.php?p=135250&postcount=272

Long = If close above TSSupertrend (5,1,10), buy at next day open.
Exit Long = If low below TSSupertrend (5,1,10).

(The opposite for short)

I know this "strategy" is not profitable. I need just a Entry/Exit Tool if my fundamental condition match.

Is there anything to note by backtesting Futures? How to set the merge policy?

Thank you very much!

Hello 7Maxx,

This indicator has multiple plots.
You will need to specify the plot you want to compare.

If the name is TSSuperTrend using a set of brackets and a barsAgo value an index would access the most recent bar of that plot.
TSSuperTrend(/*parameters*/)./*plot name here*/[0]

Close is a variable that holds a data series of closes for each bar. This is also accessed with a set of brackets and a barsAgo index.
Close[0]

In c# you will need a if statement and in the parenthesis compare the indicator's plot value with the close value.
Taking a peak at this indicator I see there is an UpTrend plot.
if (Close[0] > TSSuperTrend(/*parameters here*/).UpTrend[0])

if statements - http://ninjatrader.com/support/helpG...g_commands.htm
Close - http://ninjatrader.com/support/helpGuides/nt7/close.htm
Low - http://ninjatrader.com/support/helpGuides/nt7/low.htm

If the primary data series is less than 1 day in interval, you can use Bars.FirstBarOfSession to know that a bar is the first bar of a session.

To place an entry order such as a buy market order use the EnterLong() method call.

For an exit at a specific price, you can use a Stop or Stop Limit behind the order and a Limit ahead of the order.

Hi ChelseaB

Thank you for the answer!

I've tried to write the script with the strategy wizard, but I got a lot of error massages.

// This namespace holds all strategies and is required. Do not change it.
namespace NinjaTrader.Strategy
{
/// <summary>
/// Backtest TSSupertrend
/// </summary>
[Description("Backtest TSSupertrend ")]
public class TestSuperTrend : Strategy
{
#region Variables
// Wizard generated variables
private bool superTrend = true; // Default setting for SuperTrend
// User defined variables (add any user defined variables below)
#endregion

/// <summary>
/// This method is used to configure the strategy and is called once before any strategy method is called.
/// </summary>
protected override void Initialize()
{
Add(TSSuperTrend(5, TSSuperTrend.Utility.MovingAverageType.HMA, 1, 10, TSSuperTrend.Utility.SuperTrendMode.ATR));

CalculateOnBarClose = true;
}

/// <summary>

protected override void OnBarUpdate()
{
// Condition set 1
if (CrossAbove(Close, TSSuperTrend(5, TSSuperTrend.Utility.MovingAverageType.HMA, 1, 10, TSSuperTrend.Utility.SuperTrendMode.ATR).UpTrend, 1))
{
EnterLong(DefaultQuantity, "");
}

// Condition set 2
if (CrossBelow(Close, TSSuperTrend(5, TSSuperTrend.Utility.MovingAverageType.HMA, 1, 10, TSSuperTrend.Utility.SuperTrendMode.ATR).DownTrend , 1))
{
EnterShort(DefaultQuantity, "");
}
}

#region Properties
[Description("")]
[GridCategory("Parameters")]
public bool SuperTrend
{
get { return superTrend; }
set { superTrend = value; }
}
#endregion
}
}


I don't need a stop loss or profit target, just buy and sell on the Supertrend indicator.
