Donchian Channel

I am looking for a donchian channel. I am aware of the price channel that is already in platform, however, it is not the same as what I have been using in thinkorswim.

The price channel does not let a bar close outside of the channel like the donchian channel in tos.

An example can be found in the image:

The settings I use include:

2min timeframe

candle stick chart

90 period on the channel

I'm not sure if it is just something simple in the code already provided or if it would require an entire new indicator.

Thanks in advance!
