Sorry if this posts twice...Yahoo!, you understand.:)
Thanks for the idea(s). While noodling-around with them it occurred
to me that the problem might simply be in my "plot" code, and it
was. Here's the solution:
REC=Foreign("^Recession Ribbon","C")==0;
Plot(REC, "Recession",
colorYellow,styleOwnScale|styleArea|styleNoLabel , 0,1);
For anyone who wants to duplicate this indicator, I went to the NBER
website and got the "official" recession dates, created a csv. file
with "1" and "0" signals corresponding to the dates of economic
expansion/recession, imported the csv. into AB and went from there.
You can use the indicator ribbons to show recession periods on any
other security charts you have in AB, just drag-and-drop them on top
of a chart just like any other indicator.
