Automated Trading...algorithmic Trading..system Trading

There are a lot of chart pics and videos about system performance
results floating around all over many vendor websites. Many of the
reported replay results are phenomenal. It seems every video you see is
a winner. For some magical reason the sensitivity setting was just
perfect for that day, the money management was perfect for that day, and
the results were just perfect for that day and it was the same instrument.

The most amazing thing, however, is that on each day the settings for system sensitivity
were different. The range chart bar or time size was different. The target and stops
were different. Gee...how did the system know which sensitivity to use
for each day, and how did it know to adjust the targets, and how did it
know to change the range bar size? Intriguing questions. Simple honest
answer is that the system did not make these decisions, the user
(vendor) did. So, how did the user know? Simple honest answer is the
user did not know. But Market Replay is a wonderful thing. With it you
already know what kind of day is was, so all you need to do is adjust
the sensitivity, adjust the targets, adjust the range bar chart size and
viola! you have another perfect day.

Do not be so naive and gullible to believe that a system that has $1500
to $2000 winning days trading a 2 lot is a consistently real thing. It
is a hindsight result, with a lot of adjusting gone into the settings to
make it work perfectly. Also, did you get the part about the $500 intra
day draw down? Remember you are trading a 2 lot. Do you think such a
draw down is a realistic amount for the number of contracts you are
trading? since that draw down is way over 2% of any
reasonable 2 contract trading account. Ask yourself that if at 11am you
are up $300, and then at 1:30 you are down $500, would you still be able
to continue? Would you trust the market to give it all back to you, and
get you back into profit when all you have to go by is hindsight
results? So, unless you are a hindsight trader, market replay results
are almost completely useless.

What you need to know you will never know. You can not know in advance
what kind of day it will be. You can guess. Or, you can have a stable
consistent sensitivity setting, use a consistent range bar chart size,
use a consistent risk reward plan, and then run the system day in and
day out and see how it performs.

Look for real time results posted in real time, the same day before any
replay was possible. Or better yet, look for long term consistent
results with the same instrument, same sensitivity settings, same range
chart size, same risk reward plan. Then you can gauge the realistic
potential, the realistic intra day draw down, and the realistic
performance over time, in real time.
