Advanced Donchian Channels

アップデート済

Advanced Donchian Channels displays future donchian channel values based on the current information on the chart.
It displays a normal donchian channel at the specified user length with the future values extending from the current bar.
Depending on the direction of price movement, these values do not repaint. It is known when it does and does not repaint, and the actions are normal. See below for more information.

In a down trend, when the price is making new lows, the future "channel low" value will update every time the low is broken. The mean will also update, since the mean is the average of the channel high and channel low.
In a downtrend, the "channel high" value is concrete . It will not update until the high is broken.
Reverse these examples for uptrends.

Q;
How does it know the future values?
A:
Consider This: If we are below the current highest high, going down (aka: not setting new highs), the donchian channel "high" value will create a flat top, the flat top will start to decrease after we go further than our specified length. This is because the highest high within our specified length is no longer what it was previously. This action of time decay is a consistent movement of donchian channels . Because of this I am able to calculate these values before the current bar actually reaches them.

The indicator calculates the current length donchian channel at the current bar and then for every future bar up to your length specified it subtracts 1 from your length, calculates and displays the values accordingly.
The farthest future value is 1 length and the current bar is your specified length.

VALUES WILL ONLY BE UPDATED WHEN THE CHANNEL HIGH OR LOW IS BROKEN.
If price stays within the channel, all the future channel values will become solidified when the time reaches them.

This is not a gimmick, This data is accurate and can be used to help see future price trends

This chart should assist in visualizing what data you are seeing in this indicator.

Enjoy!
