Hi, I have simply put a Donchian channel on the price history in the top panel and all I want to do is creat a "combination condition" marker from where price history has fallen below the lower Donchian and stays on until it rises back above the top Donchian.  I tried marking the two conditions (one for fall below and one for rise above) as the first step towards a combo condition and it doesn't appear to mark anything.  I then tried the "conditon" indicator on the default Stochastics (tested rising above 50) and it marked the date fine... so I'm confused as to why it's not marking the Donchian breaches... thoughts?

Ok, so the more I look at it- I don't know if a "combo" condition would work since I'm not marking when BOTH conditions are present... I'm trying to mark the entire period from where price falls below the donchian to then back above it.  Make sense?

It reads like you want a condition for being below the Donchion Channel instead of creating conditions for crossing down through the Donchian Channel and crossing up through the Donchian Channel.

I want to mark the period of time between the sell signal and the next buy signal... where theDonchian breaches are the triggers

The # DCTop and # DCBottom lines of the following RealCode Condition were created by dragging and dropping the Donchian Channels into the Edit tab of a RealCode Condition.

So I have dumped that into the edit box of the RealCode "Add Conditon" feature... it shows up as an icon at the bottom of the chart, but it doesnt "mark" the chart like I wanted it to.   What would I be missing?

Try dragging the condition onto the chart and selecting Draw Hash Marks.

You might also want to try checking for the low being below the bottom and the high being above the top (the previous checks for the close).

it doesn't look like it is working... I wonder (as a result of the way Donchian's work with price) if I need to simply tell it "if the lower Donchian reverses down from the last bar, turn on sell signal... keep that sell signal on until upper Donchian reverses back up from prior bar"... know what I mean? as price won't stay below the Donchian like it would a moving avg... it only breaks and then the Donchian follows it lower.

I hope my question from last night made sense... my issue still remains that the code above looks to mark the ALL the points where price is BELOW the higher Donchian, whereas what I'm trying to do is have "sell signal" mark on the first time where price breaches the lower Donchian and a "buy" signal where price come back above the higher Donchian.  And in a perfect world, a paint bar scheme to mark the period between the sell and buy signal.  Is this clear? 

Thanks for the help!

Sam

And again, because of the way Donchians work... I could also say "mark the first sell signal the first time the Donchian falls... and mark the buy signal the next time the Donchian rises... then paint the bars in between (the downtrend)"... make sense?

Your technique of checking for the bottom Donchian Channel going down will return true one bar after a condition for the low crossing down through the bottom Donchian Channel.

Your technique of checking for the top Donchian Channel going up will return true one bar after a condition for the high crossing up through the top Donchian Channel.

These conditions might work for the sell and buy, but would not work to return true for the bars between the sell and buy.

The RealCode in my Tuesday, March 10, 2015 5:00:44 PM ET post is for the point scheme. It points all of the points starting where price first drops through the bottom Donchian Channel through the bar before where price breaks up through the upper Donchian Channel. So it is marking from sell signal up until the buy signal.

If you just want the sell signal you can extract the following from the RealCode for between the two signals.

'|*****************************************************************|
'|*** StockFinder RealCode Condition - Version 5.0 www.worden.com 
'|*** Copy and paste this header and code into StockFinder *********
'|*** Condition:Donchian Sell
'|******************************************************************
'# DCBottom = chart.DonchianChannels.1
'# Cumulative
If Price.Low(1) >= DCBottom.Value(1) AndAlso _
	Price.Low < DCBottom.Value Then
	Pass
End If

And if you just want the buy signal you can extract the following from the RealCode for between the two signals.

'|*****************************************************************|
'|*** StockFinder RealCode Condition - Version 5.0 www.worden.com 
'|*** Copy and paste this header and code into StockFinder *********
'|*** Condition:Donchian Buy
'|******************************************************************
'# DCTop = chart.DonchianChannels.0
If Price.High(1) <= DCTop.Value(1) AndAlso _
	Price.High > DCTop.Value Then
	Pass
End If
