Hello cbart_1,

Can you please check if you are receiving any errors on the Log tab of the Control Center when using a displacement value of 2 in your original snippet? There isn't any reason that shouldn't work as well as long as you are ensuring you have enough bars on your chart. Please see our Tips section for information on this:

Please try adding the following snippet to the beginning of your code in OnBarUpdate()

if (Current Bar < 2)
return;

You need to ensure you have enough bars on the chart to calculate correctly. If youre looking back 2 bars, you need to check for less than 2... if using 5 you would need to check for less than 5.

If you're assigning a variable like "displacement" a number, you could also use (if CurrentBar < Displacement) and this will ensure that you're checking for enough bars to meet the displacement value requirement.
