Struggling to create indicator that uses Highest and Lowest values

[AdithBlack]

I'm trying to convert this indicator from Pinescript into ninja, I've tried to use High[HighestBar]/ Low[LowestBar] but it didn't give the same results

length = input(20)
// Calculate upper and lower bands
upperBand = ta.highest(close, length)
lowerBand = ta.lowest(low, length)

//// calculate highest lowerBand for the last however many bars
lb = ta.highest(lowerBand, length)

////////plot line
plot(lb, color=color.white)

Hello AdithBlack,

Thanks for your post.

From my understanding, the ta.highest() function notes in the Pinescript documentation that this function returns that highest value for a certain number of bars back. The ta.lowest() function returns the lowest value for a certain number of bars back.

In NinjaScript, you could use MAX() to get the highest value over the specified period. MIN() could be used to get the lowest value over the specified period.

See the help guide documentation below for more information about these methods and sample code.

MAX(): https://ninjatrader.com/support/help...aximum_max.htm
MIN(): https://ninjatrader.com/support/help...inimum_min.htm

AddPlot() would be used to add a plot to the script. Values could then be assigned to the plot using Value = x, where x is the value you want to assign to the plot.

This help guide page contains more information about AddPlot() and sample code: https://ninjatrader.com/support/help...t8/addplot.htm

Please let me know if I may assist further.
