Accessing Bar Data

[tupchurch]

I am trying to get the close and the RSI for the last 14 bars. As a test I tried to get the data for 5 bars back.

DrawTextFixed("X", Close[-5] + " - " + RSI(14,3)[-5], TextPosition.TopLeft);

I am getting an out of range error.
What is the best practice method for getting the data I am looking for?

Thanks

Hello tupchurch,

To access 5 bars back you would use a positive number like "Close[5]" and "RSI(14,3)[5]"to get 5 bars back inside of NinjaTrader.

Here is a good thread that goes over using the Brackets "[]" inside of NinjaTrader to access previous values that you may view.

Using positive five is when I get the out of range error. Your link doesn't address this problem. I tried using if (Bars.Count > 20) but it didn't help. What is the best practice method of avoid the out of range error at the beginning of a series?

Hello tupchurch,

To make sure that you have enough data before you start to make your calculations you will want to use "CurrentBar" to check to see what bar is being processed. So in your example:

protected override void OnBarUpdate()
{
    // Makes sure there is at least 15 bars before moving on
    if (CurrentBar < 14)
        return;

   // Rest of code that can access up to 15 bars ago.
}

Got it, thanks.
