OnBarUpdate with oneachtick

[tonynt]

Hello,

I made my indicators with COBCtrue and I know how to do with "if(....) return;" and all works ok.

Now I run an indicator on each tick and I want to compare the current/developing volume with the volume of the bar before and plotting me backcolor to see easily when volume is higher.

I have in onbarupdate
if (BarsInProgress != 0) return;
if (CurrentBars[0] < 2) return;
if(VOL1[0] > VOL1[1] || VOL1[0] > VOL1[2]) BackBrush=Brushes.White;

In log tab I get the error message

15.12.2020 15:49:18	Default	Indicator '': Error on calling 'OnBarUpdate' method on bar 2559: 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.

What am I´m doing wrong here please?

Thank you!
Tony

Hello Tony, thanks for your post.

I made a test script that works fine with a single series:

If your script has a secondary series, make sure there is at least 2 bars on that series as well e.g. if (CurrentBars[0] < 2 || CurrentBars[1] < 2) return;

Please let me know if I can assist any further.

Hello,

thank you for your reply. I thought there is something different when running on eachtick. So the message seems to be from another indicator.

Best regards
Tony
