EMA Indicator - Strategy errors from No Values in first few Bars

[cpabiz20k]

I am getting errors saying the program cannot access EMAClose[2] because it is out of range. It takes about 15 bars for the EMA to calculate and begin to display on my chart. How do I code around that fact? I need it to wait 10 bars on the first day of data (not every day, just the first). After that initial period it displays. I am lost on how to code for that. Any help is appreciated.
Thanks

Hello cpabiz20k,
Thanks for your post.

This is a common error that is caused when a script tries to access an index that is not yet valid. The specific check you need to do will be highly dependent on your own custom logic.

You can resolve this error by implementing the concepts in the help guide page at the following link: https://ninjatrader.com/support/help...nough_bars.htm

Let me know if you have any questions.
