Need help on donchain channels

Does anyone know how I can manually draw donchain channels? and also, if anyone has an indicator plug in for metatrader that would be fantastic! (but I would also like to know how to draw them myself)

Really appreciate any input or help thank you

I don't use this indicator but it seems to work fine.

The Donchian Channel is simply the highest point from now to x bars ago, and the lowest point from now to x bars ago. The default setting is usually 20 periods, so in that case, you would look at the last 20 bars, find the highest and lowest price, and draw a dot/line on the current bar where those points are.

It is the basis of the famous Turtle system for an entry signal. Basically, you buy/sell on the breakout of the channel, because it is assumed that the high/low points were created by recent consolidation in the market. Like most breakout systems, expect a lot of losing trades, but being offset by large reward to risk ratio.

Under the inputs of the indicator it has "extremes". Any idea what is meant by that and how it effects the channels?

Thank you
