BarsInProgress Issue

[lee612801]

Hello,

I'm trying to use a multi-bar series but I keep getting the "You must use the overload that has 'BarsInProgress' parameter" error when I try to execute the code. It looks like this:

protected override void Initialize()
{
CalculateOnBarClose = true;
Add("XXX", PeriodType.Day,1);
}

protected override void OnBarUpdate()
{
// Only run on real-time data
if (addHistoricalData==false)
{
if (Historical == true)
{
return;
}
}

if (CrossBelow(XXXX, XXXX))
{
if (BarsSinceEntry("Trade") > XXX)
{
EnterLong(1, DefaultQuantity, "Long");
}
}

if (BarsSinceEntry() >= XXXX)
{
ExitLong(1, "BarsExit", "Long");
}
}

Where do I need to add the BarsInProgress? If I want the first bars object (0) as the signal but then trade the second bars object (1), what do I need to do when I'm using the BarsSinceEntry/Exit?

Thank you,

Regards,

Lee

Hello lee612801,

Thank you for your post.

Add if(BarsInProgress == 0) and wrap your conditions in the brackets (as seen below). For the BarsSinceEntry, you would use BarsSinceEntry(int barsInProgressIndex, string signalName, int entriesAgo) .

For example:

protected override void OnBarUpdate()
{ 
// Only run on real-time data
if (addHistoricalData==false)
{
if (Historical == true)
{
return;
}
}

if(BarsInProgress == 0) // check conditions on primary bar series
{
if (CrossBelow(XXXX, XXXX))
{	
if (BarsSinceEntry(0, "Trade", 0) > XXX)
{ 
EnterLong(1, DefaultQuantity, "Long");
}
}

if (BarsSinceEntry(0, "Trade", 0) >= XXXX)	
{
ExitLong(1, "BarsExit", "Long");
}
}
}

I recommend reviewing the documentation on using multiple time frames or instruments in your code at the following link: http://www.ninjatrader.com/support/h...nstruments.htm

Please let me know if you have any questions.

Hi Patrick,

Thank you for your help. I got it to work with your code but I had to remove the initial if(BarsInProgress == 0) and change the BarsSinceEntry to (BarsSinceEntry(1, "Trade", 0). Not sure exactly why this is the case, but its not working!

Thank you so much for the prompt response and solution.
