It is deeply embarrassing to me as ET's premier technical analyst to have to withdraw an Undicator I worked so long to develop (10 minutes). But I received too many PMs (Pissy Messages) from SCT traders who said they simply could not use it. The typical plaint was "I expect an Undicator to have a high value when I should trade and a low value when I shouldn't!" I tried patiently to explain that decreasing values corresponded to decreasing uncertainty, but it appears that few SCT traders are old enough to have read Mamis (if, indeed, they read the classics at all). So I took the absolute value of Volatoilety-1 and named the new Undicator as Tradeavolity. Now increasing values indicate that you should trade, and correspond to increasing certainty. My apologies to all my SCT friends, whom I know are counting on me to simplify the method so that any ETer, no matter how doltish, can trade it with confidence.
