[thomson]

I create an indicator with dataSeries. How can I get data series before value?
I try to use the code as below,
myDataSeries.Set(myDataSeries[1]);
there have an sytax error.

Please advise,

What sort of error are you receiving?

I'm not seeing anything here that would throw an error unless you're getting an out of bounds error message in the output window.

When I compile the code,I got a error ; expected.
How can I get 1 bar before dataseries value? How to set the current dataseries value equal to the before bar's dataseries' value?
Thanks,

It might be there is a syntax error elsewhere in your code or you forgot to end a line with a ;

Could you attach your code or a sample that replicates the issue?

I found the error, thanks for your help. I add more . in my code.
myDataSeries.Set(myDataSeries.[1]);
