how to limit entries to one

[shanemcdonald]

A strategy that I am testing will enter 2 positions long or short many times.
How can I limit the positions to only one at a time ?

thanks

shane,

You can use entries per direction here :

Shane,

I may need to see a code sample of your order entry and maybe even initialize method. You could always obfuscate the entrance conditions, etc. if you don't want to share everything.

for example :

if ( CrossAbove(SMA(10),SMA(25),1) )
{

EnterLong();

}

All I need is :

if ( my_conditions_are_here )
{

EnterLong();

}

/// <summary>

protected override void Initialize()
{
Add(RSI(Period, Smooth));
Add(RSI(Period, Smooth));
Add(RSI(Period, Smooth));
Add(RSI(Period, Smooth));
SetStopLoss("", CalculationMode.Percent, 1, false);

CalculateOnBarClose = true;
}

/// <summary>
/// Called on each bar update event (incoming tick)
/// </summary>
protected override void OnBarUpdate()
{
// Condition set 1
if (Rising(RSI(Period, Smooth).Avg) == true
&& RSI(Period, Smooth).Avg[0] > 60)
{
EnterLong(DefaultQuantity, "");
}

// Condition set 2
if (Falling(RSI(Period, Smooth).Avg) == true)
{
ExitLong("", "");
}

// Condition set 3
if (Falling(RSI(Period, Smooth).Avg) == true
&& RSI(Period, Smooth).Avg[0] < 40)
{
EnterShort(DefaultQuantity, "");
}

// Condition set 4
if (Rising(RSI(Period, Smooth).Avg) == true)
{
ExitShort("", "");
}
}

#region Properties
[Description("")]
[GridCategory("Parameters")]
public int Period
{
get { return period; }
set { period = Math.Max(1, value); }
}

[Description("")]
[GridCategory("Parameters")]
public int Smooth
{
get { return smooth; }
set { smooth = Math.Max(1, value); }
}
#endregion
}

Shane,

I think the issue is here :

// Condition set 2
if (Falling(RSI(Period, Smooth).Avg) == true)
{
ExitLong("", "");
}

// Condition set 3
if (Falling(RSI(Period, Smooth).Avg) == true
&& RSI(Period, Smooth).Avg[0] < 40)
{
EnterShort(DefaultQuantity, "");
}

These can occur at the same time. I would suggest trying the following :

// Condition set 1
if (Rising(RSI(Period, Smooth).Avg) == true
&& RSI(Period, Smooth).Avg[0] > 60)
{
EnterLong(DefaultQuantity, "");
}
// Condition set 4
else if (Rising(RSI(Period, Smooth).Avg) == true)
{
ExitShort("", "");
}


// Condition set 3
if (Falling(RSI(Period, Smooth).Avg) == true
&& RSI(Period, Smooth).Avg[0] < 40)
{
EnterShort(DefaultQuantity, "");
}
// Condition set 2
else if (Falling(RSI(Period, Smooth).Avg) == true)
{
ExitLong("", "");
}

You may also want to check that your "Default Quantity" is set to 1 in your strategy properties when you run a backtest or attach to a chart.

The answer to your question, and pretty much the question itself, is the same as the answer that I gave in this thread.
