Access historical bars via Low[]

[Joost]

I have used Metatrader 4 so far and am currently in the process of becoming friends with NinjaTrader.

I would like to access historical bars using Low[] in an indicator.

For Low[0] this seems to work. See example 1.

It doesn't seem to work for Low[10] . See example 2.

Can someone explain why Low[10] doesn't seem to work?

Seems like a silly, simple problem, but I just can't figure out the solution....

Hello Joost,

You are likely seeing an error here, its best to keep the control center log tab and NinjaScript output window in view while testing scripts. The problem is that you can't use 10 bars ago before processing 10 bars. Your script always starts at bar 0 and works forward, trying to access 10 bars ago on bar 0 doesn't make sense because there are not 10 bars before bar 0.

To fix this type of problem you can check the CurrentBar. NinjaScript is C# language so you can use features like return to stop code execution past that point based on a condition.

if(CurrentBar < 10) return;
// do something with Low[10] after this point

Perfect, thanks.
