Maximum and minimum prices of the last 10 periods

[villarroel0401]

I need to pass the max price and min price to variables.

I read the following pages:

https://ninjatrader.com/support/helpGuides/nt8/NT%20HelpGuide%20English.html?highestbar.htm

https://ninjatrader.com/support/helpGuides/nt8/NT%20HelpGuide%20English.html?lowestbar.htm

The code would be this:

###################################

int highestBarsAgo = HighestBar(High, 10);

double highestPrice = High[highestBarsAgo];

###################################

###################################

int lowestBar = LowestBar(Low, 10);

double lowestPrice = Low[lowestBar];

###################################

When running the strategy, it gives me the following error: (I attach a screenshot of the error message)

Hello villarroel0401,

Thanks for your post.

Does the error message only appear when running the NinjaScript strategy that you created on a new blank chart window?

In the strategy, are you using a CurrentBar or CurrentBars check to ensure that at least 10 bars have been processed in the data series you are accessing in the script?

If not, please add a CurrentBar check to make sure that there are enough bars processed for the data series you are accessing.

Make sure you have enough bars: https://ninjatrader.com/support/help...nough_bars.htm

Prints should also be added to the script that print out the indexes you are accessing and the CurrentBar to see how that logic is evaluating. Note that the index you are accessing in the script cannot be larger than the CurrentBar index.

Below is a link to a forum post that demonstrates how to use prints to understand behavior.
