The code below posted by Graham Kavanagh seems to give the same result as
MetaStock values.

Thanks, runs.
But doesn't really look the same as my friend's Bullcharts Kagi
indicator. His steps are far wider and flatter, and encompass whole
swings, whereas this appears to step for every candle. Changing the
paramater doesn't seem to help much.
Any suggestions?
