Donchian/ Hi Low Channels with 50% retracement?

Hey everybody, just trying to see if I can locate an indicator for MT4...basically a Donchian Channel with a 50% retracement line inside the channels...I had one way back when but my MT4 shit the bed and when I reloaded everything, all my indicators were gone...

Can someone help? Thanks!

Squall, is the 2nd post in this link any use?

Also found the attached mq4's among my collection.

Sorry, I haven't studied Donchians, so I'm not sure how much help, if any, these might be. Perhaps they could be easily modified to suit (i.e. add the 50% retracement line)?
