Thank you, Don
I have that code but the output does not agree with the Guppy
MetaStock output. I have BK (Bank of NY Mellon) on my screen in both
AmiBroker and MetaStock - CBL is 34.19 in AB and 34.93 in MS also the
line drawn is much different. MS allows for the lookback period to be
changed (set at 10 periods now) but I cannot find the countback
period in the CBL code! The AB CBL is also below the last price bar -
not a good entry point! In fact it is below the last 5 price bars,
whereas the MS CBL passes through the last 6 (six) price bars.
