Standard Deviation Channels (ThinkorSwim identical)

Saw the standard deviation channels indicator on ThinkorSwim and found a way to replicate it. However, the full range (kind of useless feature) is not the same as ThinkorSwim, but using without full range and setting your own length will be identical to the same length on ThinkorSwim. If you have any recommendations of your trading strategy using this, how to make the script better or any additions, they would be very helpful to suggest.
