OnBarUpdate error

[designer01]

I created a strategy but when enabled in chart I get this error (See quote below). I believe there is a snippet I need to add in the code but forget which one. Please advice. Thanks.

Error on calling 'OnBarUpdate' method on bar 0: You are accessing an index with a value that is invalid since it is out-of-range.
I.E. accessing a series [barsAgo] with a value of 5 when there are only 4 bars on the chart.

Never mind I figured it out it's this snippet below.

if (CurrentBars[0] < 5) //Need more than 5 bars to trade
            {
                return;
            }​

Hello, thanks for writing in. You likely are accessing a series 1 bar ago on the first bar on the chart e.g. Close[1] would throw this error on CurrentBar == 0. Add this to the top of OnBarUpate:

if(CurrentBar < 1) //1, or the max lookback in your script.
return;
