OnBarUpdate error

[futuros]

I have coded a new strategy for NT8 that is giving the following error "Error calling 'OnBarUpdate' method on bar 4808: the given path format is not supported."

Bar 4808 was the last bar/current bar on the chart, I don't know what triggers this error and what means "the given path format is not supported", I searched around the whole forum and couldn't find a similar error, could you please someone give me a hand with this? thanks.

Here is the code:

protected override void OnBarUpdate()
{
if( CurrentBar < BarsRequiredToTrade ) {
return;
}

base.OnBarUpdate();

// Check to see if we're in a time parameter
if( time2trade() == false ) {
return;
}

if( Position.MarketPosition == MarketPosition.Flat )
{

if( macd.Avg[0] > 0 // signal line above zero
&& macd[0] > macd.Upper[0]
&& macd[1] <= macd.Upper[1] ) // cross up
{
doLong();
}

else if( macd.Avg[0] < 0 // signal line below zero
&& macd[0] < macd.Lower[0]
&& macd[1] >= macd.Lower[1] ) // cross down
{
doShort();
}
}

if( isBullishSoundSignal == false
&& macd.Avg[0] > 0
&& macd[0] < macd.Upper[0] )
{
isBullishSoundSignal = true;
}
else {
isBullishSoundSignal = false;
}

if( isBearishSoundSignal == false
&& macd.Avg[0] < 0
&& macd[0] > macd.Lower[0] )
{
isBearishSoundSignal = true;
}
else {
isBearishSoundSignal = false;
}

if( SoundAlert )
{
if( isBullishSoundSignal )
{
PlaySound( string.Format( @"{0}sounds\{1}", NinjaTrader.Core.Globals.InstallDir, SignalSignalSoundFile ) );
}

if( isBearishSoundSignal )
{
PlaySound( string.Format( @"{0}sounds\{1}", NinjaTrader.Core.Globals.InstallDir, SignalSignalSoundFile ) );
}
}
}

It might be that it doesn't like where the @ symbol is placed

instead, try something like

PlaySound( NinjaTrader.Core.Globals.InstallDir + @"sounds\" + SignalSignalSoundFile );

OR

PlaySound( string.Format( "{0}sounds\\{1}", NinjaTrader.Core.Globals.InstallDir, SignalSignalSoundFile ) );

I hope that helps

Thank you Gubbar924, I tried both changes, none of them worked...

Are you still getting the same error message? If it is different, what does it say?

Would you mind posting the script here or sending it to me directly? I can take a look for you.

In the meantime, check out this sample I put together.
It allows you to pick a .wav file from within the strategy's properties window.

It is set to sound an alert when connection is lost.
To test it, just make sure you're connected to your data feed/connection and that the strategy is enabled; tthen use your firewall to block all connections, or disconnect the ethernet/wireless from your computer, wait about 10 seconds for NinjaTrader to see it as connection lost. At this point it should play the .wav that you've selected.

Hi gubbar924, I still getting the same log error (it is not a compiling error), if you give me your e-mail address I can send you the script, thanks

Thank you for your assistance, gubbar924.

futuros,

Thank you for your patience.

We can look into this further on our end as well. You can export your indicator by going to Tools > Export > NinjaScript Add On > Add > select your indicator > OK > Export > name the file 'NTsupport' > Save. The file will be located under Documents\NinjaTrader 8\bin\Custom\ExportNinjaScript. Please attach the file to your response. You can attach the file to your response or send it to platformsupport[at]ninjatrader[dot]com with 'ATTN: Patrick H' in the subject line and a reference to this thread in the body of the email.

Hi Patrick, it is a strategy, not an indicator...I already sent the strategy by email to your attention, thanks for your help!
