Streamwriter: any way to avoid multiple duplicative lines?

[catinabag]

Hello there,

When I Streamwrite chart data, if the script involves multiple data series, the CSV output will have multiple lines for each bar.

Would you happen to know a way to avoid this from the outset? I don't mind cleaning up the data, and I suppose I could figure out a C# approach to do that, but it would be easier if the CSV just came out with a single row per bar.

I would greatly appreciate any help!

Thank you

Assuming you use Streamwriter in a NinjaScript strategy. Try something like this where you currently have your Streamwriter logic in OnBarUpdate().

if (BarsInProgress==0) // 0 is the MAIN bars array
{
....process the Streamwriter data output logic here
}

Did I understand the situation properly? -Bill-

Good morning, and thank you, NoLoEffeCo; that worked great!

Moreover, I have learned something new which, no doubt, will come in handy in the future.
