Donchain Channels working or not


Guest dippy1999

Question

Guest dippy1999

I am new to this so bear with me.  I don't think the Donchian Channels are working properly on the platform.

Below you will see that I have set the Donchian to 20.  Yet, as you can see by the measure tool, c. 20 days after the new low, the bottom line of the Donchian Channel has not moved back up to where it should be (i.e. it has not moved up to the point which shows the low of 20 days before.  I have found several examples of this. 

Can someone put me right please?

I'll caveat this with it being a quick reply rather than something I have investigated - but don't you want to be looking at the number of bars rather than the number of days. Given this being 20 days it obviously goes over weekends (which print as a 'day' but not as a 'bar') and therefore you just need to expand it out a little further to 20 bars?

If you need a more official IG response i'll need to go investigate so let me know.

Thank you @JamesIG - I think what you are telling me is that I was thinking (wrongly) that the Donchian Channel would show highs and lows of 20 calendar days; whereas the Donchian Channels are actually based on business days (plus one day for each weekend).

Not sure what you mean but 

a 20 period Donchian low should be the lowest low on every data set of 20 periods

could be the first bar or the last

Thanks
