Not enough data?

[rolfwidmer]

Hi, I am using several instruments (currencies) to calculate overall currency strength. In the calculation I get for some pairs a message "Error on calling 'OnBarUpdate' method for indicator 'CurrencyStrength' on bar 0: You are accessing an index with a value that is invalid since its out of range. I.E. accessing a series [barsAgo] with a value of 5 when there are only 4 bars on the chart.". If I open a chart with the related instrument (where the error happens), I have all data loaded. What could be the problem?

Hello Rolf,

This message is not caused by the amount of bars on your chart, but how/when you access values in your script.

If you access, for example, Close[1], on bar 0, this value is not available and you would get that message.
