How to access historical Bar values in my ninja strategy code 4 real time data feed

[sjpande]

hi All,
I need some help here, where I need to access the previous day's bar values (like high . low, EMA values ) when my strategy code is being executed on real time data.
How do I access it?

when I use lets say for example
Close [10] or Close[16] on hourly chart, i get below error:
Error on calling 'OnBarUpdate' method on bar 100: 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.

Hello sjpande,

Thanks for your post and welcome to the NinjaTrader Forums!

This error message indicates that you are trying to access a BarsAgo value that is not valid. A more simple example using one series would be on bar 5 you check for 6 BarsAgo. There are not yet 6 bars so the CurrentBar minus 6 would be a negative number or a non-existent bar.

A CurrentBar check could be used in your indicator's logic to ensure that a certain number of bars have been processed before the indicator begins calculation. A CurrentBar check would look something like this.

if (CurrentBar < 10)
    return;

This would check to make sure that 10 bars have been processed before the indicator begins its calculations.
