OnBarUpdate Error

[RodS7]

I am getting the following error message in a multi-timeframe strategy:

" **NT** Error on calling 'OnBarUpdate' method for strategy 'ZLReMTF/e610e684089b44a2b751f1e4043ed90d': You must use the overload that has a 'BarsInProgress' parameter when calling the BarsSinceExit() method in the context of a multi-time frame and instrument strategy."


The code associated with BarsSinceExit is:


if(BarsInProgress == 0)
{
TimeSinceExitOK = BarsSinceExit() >= 1 || BarsSinceExit() == -1;
TimeSinceEntryOK = BarsSinceEntry() >= 1 || BarsSinceEntry() == -1;
}


Anyone have any ideas?

Hello,

BarsSinceExit() has an overload for the barsInProgressIndex that needs to be specified in an multi series script.

BarsSinceExit(int barsInProgressIndex, string signalName, int exitsAgo)

For example,

if(BarsSinceExit(1, "mySignal", exitago) == 1)

Where 1 is the BIP

I must be doing something wrong...

I am getting the same error


I have changed my code as follows

TimeSinceExitOK = BarsSinceExit(1,"ZLRe1",0) >= 1 || BarsSinceExit(1,"ZLRe1",0) == -1;
TimeSinceEntryOK = BarsSinceEntry(1,"ZLRe1",0) >= 1 || BarsSinceEntry(1,"ZLRe1",0) == -1;

In your post, you used the barsInProgressIndex of 1. That is not the primary data, is it?

[NinjaTrader_Matthew]

barsInProgressIndex of 1 would be the second data series.


The primary series is 0. Do you continue to receive errors if you use 0 as the bIP Index?

my mistake - I had changed to '0' but I had missed one instance of BarsSinceExit in the code

problem solved

thanks
