Hi Ara,
What's with all this Blank(Name) business, anyway? ^_^
To venture an answer to your question, I don't think one can predict
a breakout. But one can know that breakouts overwhelmingly spring
from periods of consolidating volatility. When? We don't know. But
breakouts very rarely come out of periods of relative high
volatility.
So we watch when things get quiet, and we wait. It can really put
you to sleep sometimes, because it's a waiting game, that suddenly
and with little warning becomes an action game. People tend to
prefer action to waiting. Waiting is somewhat boring.
To compound the difficulties, not all breakouts go on to do great
things. Some fail. This can cause hesitation just at the time
action is finally required. The way to overcome the hesitation is to
have the entire plan ready before the alarm bell (finally) rings. Not
half the plan ("I need to buy something."), but how much I'm going to
buy, what is my ultimate objective (not just "to make some money"),
and specific actions I'm going to take contingent on what price and
volume do. Since they can do several things, I need several plans. We
need a plan for being wrong, a plan for being modestly right, and a
plan for being spectacularly right. Impromptu doesn't keep the sushi
from sliding off the rice. ^_^
