is Discretionary Trading?<<

I am not sure what you mean by 'based on market behaviour', maybe
that's the discetionary part, but from the statistics you quoted,
there is no way to tell if the trades were mechanical or discretionary.

Why do you think Joe was only able to get 100 ticks out of an average
200 tick move? This was not some obvious 200 tick price move that
everyone noticed. This was a stealth move that looked different
everyday, was not exactly 200 ticks everyday and was only discernable
to the most observant traders and may have required more than one
trade to extract 100 ticks.

>>how did Joe know that it was 4/5 days, 200 ticks, 90% wins,
10.45AM. Did he computer test, write it down with pencil and paper or
see it in the tealeaves?<<

He discovered it through observation that's why it requires
perspicacity to be a good DT.

>>if Joe had been a competent AB user, at the time, do you think it
would have been possible for him to code and automate that trade (if
he wanted to)?<<

Not likely.

All DT's don't trade the same way but the biggest difference between
mechanical and discretionary traders is in trade management (also
called trade exit).

Trade exit is more important than trade entry because it determines
whether or not you make a profit (it's possible to trade profitably
with random entries).

MT's have fixed rules for entry (like buy when 8MA is above 12MA and
RSI crosses above 30), an initial stop and fixed rules for exit (like
use a 5 ATR trailing stop). It is a 'set it and forget it' style of
trading.

DT's have an entry point based on what they see, an initial stop
(which Joe calls a catastrophic stop because he never expects it to
get hit), and an initial exit strategy. Once a trade is entered, DT's
monitor price action, indicators, whatever and manage the trade. If
things don't go according to plan, they may exit the trade, move their
stop up, reduce their profit target, etc. What they don't do is sit on
their hands and wait for either their initial stop to get hit or their
initial exit strategy to take them out of the trade.

If you want to be a DT, you will need a lot of screen time studing
price behavior et al.

Here is a quote from Mike Reed's (DT, day trader specializing in stock
index futures) online article "10 Steps to Professional Day Trading"

"Advice on Day Trading: Rule #1  - Practice exiting trades at
break-even, using a one-tick target, a two or three tick soft stop
(mental stop) and a 1.5 point hard stop. Never *allow* the market hit
your hard stop. Exit by moving your target toward your hard stop, not
by moving your hard stop towards your target. With time, all of this
must become a reflex. You won't always be able to keep your losses
down to 2 ticks, but only on rare occasions should you find yourself
letting the market hit your hard stop. ("Rarely" means only about once
every 50-100 trades after you get the hang of it.)"

Lance Beggs is a DT who uses price action and support/resistance and
has a very good website with links to mostly his own free educational
videos (includes one of Mike Reed's, aka tradestalker).
