Bars indices out of range

[Stanfillirenfro]

Hello!
is there here in Ninjatrader away to solve such problem?
I am building a strategy, but I am facing a problem while compiling the code. I am reciving the message like: " Error on calling 'OnBarUpdate' method on bar 14: 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."

I have the following code:

if(CurrentBar < 14) return;
for(int i = 14; i >= 0; i--)
{
    double  myRsi = RSI(14, 3)[i+8];
}

When I have: if(CurrentBar < 0) return;, I received the error message already for the bar 0;

In my code, when i = 14,

 myRsi = RSI(14, 3)[14+8]

,
what ist already beyong the 14 I have in my loop.

How could I solve this problem since I am frequently encountering such problems in my codes? Which condition could be suitable in this case so that I could have the value of myRsi at position 14+8 for example?

if (CurrentBar < 14+8) return;

Hello Stanfillirenfro,

Thanks for your post.

bltdavid is correct. You would need to ensure that there are enough bars loaded on the chart for the data being processed. For example, if you want to call the RSI with a barsAgo value of 14 + 8 (22), then you would need to use a CurrentBar check to see if 22 bars have loaded. ( ex: if (CurrentBar < 22) return; )
