Is it possible to include Donchian Channels on a Version 7 chart?  Thanks!

Yes, there a a couple of options. You could add separate Custom Indicators with Plot using price scale checked for the top channel, bottom channel, and even the centerline if you wanted. The Formula setting for each of these indicators is given below.

Top Channel:

MAXH20.1

Bottom Channel:

MINL20.1

Centerline:

(MAXH20.1 + MINL20.1) / 2

Note that the above is for a 20 period Donchian Channel with a 1 period offset, but you can change both of those values in the formulas given a above.

You could also use a Custom Price Channel Indicator instead.

Indicator Line Formula:

(MAXH20.1 + MINL20.1) / 2

Channel Width Formula:

(MAXH20.1 - MINL20.1) / 2

This is again for a 20 period Donchian Channel with an Offset of 1, but you can change this as desired.

Hi Bruce,

I would like to program:

Donchian channel high ( 12 periods ) was moving down and has reversed up in the last 20 days.

Can you help  me ?

Thank you,

Kind regards Rob

Please try the following.

TrueInRow(NOT(MAXH12.1 > MAXH12.2), 20) < SinceTrue(MAXH12.1 < MAXH12.2, 20)

perfect Bruce !

Thank you !

You're welcome.
