TKO scan

Audax

Dave Landry has mentioned that, in time, his indicators and scans will be available on StockCharts.
In the meantime, it would be handy to have a scan narrowing down candidates for his favorite pattern, the TKO (Trend Knock Out). I've found one on TC2000, written by Bruce, their chief advisor, but my attempts to write an equivalent in the StockCharts scan language have foundered on getting the "Max" function to count back from successive days.

Here is the TC2000 version - any suggestions would be much appreciated:

A formula for a 20-bar high happening during one of the prior 8-bars with all of the highs since being below this high could be written as:

(H < H1 AND H1 = MAXH20.1) OR (MAXH2 < H2 AND H2 = MAXH20.2) OR (MAXH3 < H3 AND H3 = MAXH20.3) OR (MAXH4 < H4 AND H4 = MAXH20.4) OR (MAXH5 < H5 AND H5 = MAXH20.5) OR (MAXH6 < H6 AND H6 = MAXH20.6) OR (MAXH7 < H7 AND H7 = MAXH20.7) OR (MAXH8 < H8 AND H8 = MAXH20.8)

I think you would start with

and [8 days ago high = 8 days ago max(20, high)]

and [8 days ago high > max(7, high)]

Then adjust the parameters for each of the subsequent days, and wrap it all in an "or" statement.

That's a great help, many thanks.
