=======================================================
I think from Equis excellent article, that you have "filled" the last alineas
missing longer term Coppock Curve - LT Momentum indicator.
Sure looks like a TRUE curve, if you ever have the chance to send a copy
of the article, I'd be much obliged.
1. (Close-Ref(C,-300))/(Ref(C,-300)*0.01)
2. (Close-Ref(C,-240))/(Ref(C,-240)*0.01)
3. Mov((Close-Ref(C,-300))/(Ref(C,-300)*0.01)+
(Close-Ref(C,-240))/(Ref(C,-240)*0.01),220,W)
Thanks for posting,
Regards,
Ton Maas
