// Interested in measuring a short-term Trend ?
//
// Price persistency is the number of days that a market continues to
close
// either up or down. It's another term for a market run. The
usefulness of
// Price Persistency is based on the theory of runs..It is the idea that,
// given the market has moved in a particular direction for ( n )
days, the
// likelihood it will either continue..or not...can be estimated and
used in a
// profitable trading system....

Auto-Optimization Framework
v 1.0 (hah) 10/20/03 Dave Merrill (email: dmerrill at usa dot net)
thanks to Tomasz Janeczko for AmiBroker, and everyone in the AmiBroker
groups at Yahoo
comments, suggestions, bug reports etc are most welcome
------------------------------------------------------------------------
WHAT DOES THIS DO?
you've probably done walk-forward optimizations, where you optimize a
trading system over some time period, then trade with those settings
for a while, optimize again at some later date, trade on, etc.. in
fact, this is like real life, unless you assume your initial settings
will be optimal forever and you'll never change them.
this code is a backtest framework that does this continously and
automatically. you provide a trading rule, and it constantly optimizes
the parameters for it, always using the settings that measure best
over a selectable lookback period. this re-optimization can be done
every bar, at a user-definable interval, or once at the start of trading.
one interesting fact is that so far, almost no trading rules I've
tested are very profitable when managed this way, with any framework
settings I've tried. the ones that are are far from universally
successful over various stocks and time frames. I find this very
interesting and quite puzzling, as is well documented on the AB group.
maybe there are bugs that cause this; please let me know about any you
find. maybe the equity evaluation function or other framework
behaviors could be improved; please let me know if you come up with
great changes. maybe it's just not a very effective method; if you can
explain to me why this is so, please do!
and lastly, if you find any hugely profitable uses for this thing, or
other interesting insights from poking around with it, PLEASE let me
in on 'em! (:-)
IMPORTANT USAGE NOTE!!!!
parts of this code belong to the framework itself, and shouldn't be
modified in normal use. other parts you need to edit, to select the
specific trading rule you want to test, and establish settings for how
the framework will operate.
all sections are clearly labelled as editable or not. it's in your
best interest not to change the ones that say NOT EDITABLE, at least
to start with.
DON'T BE IMTIMIDATED
though this is pretty long, it's actually not that complicated, either
to use or in its internals. it's broken down into sections, most of
which you don't need to even look at. if I could hide the no-touchy
bits away I would (:-). also, a lot of it is explanation, not code,
and a lot of the code is a collection of sample trading rules.
INSTRUCTIONS
1) add trading rule(s) you want to test to the CUSTOM TRADING RULES
section. see comments there for how your rules will be called, and
what they need to do. some examples are provided. you can have as many
rules here as you want, but only one can be in use at a time. step 3
below controls which one is active.
2) if those rules require other custom functions, add them to the
CUSTOM UTILITY FUNCTIONS section.
3) edit the framework function BuySellRule(), at the start of the
FRAMEWORK CONFIGURATION section, to call the trading rule you want to
test now.
4) edit the SetParameterRanges() call, next in the FRAMEWORK
CONFIGURATION section, to set the ranges over which you want to test
each of the two optimization parameters. some examples are provided;
comment out all but the one you want to use.
5) if desired, edit the rest of the FRAMEWORK CONFIGURATION section,
to control various aspects of how the framework itself behaves.
6) set the AA range, stock universes you want to test, and other AA
settings, then run a Backtest or Portfolio Backtest.
7) if you want to see the parameters selected and other decisions
being made under the hood, you can Explore instead of backtest. if
desired, edit the EXPLORATION section at the end to change the columns
and bars displayed; some possible extensions and modifications are
provided. note that exploring doesn't actually trade, it's only a
readout for your interest.
GETTING STARTED
this comes set up to run the included trading rule 'BuySellCCI'.
backtest it on, say, the NASDAQ Composite Index, to get an idea of how
it performs (nothing great). explore it to see the parameter values
the framework selected (the best_p1 column). try changing the
parameter ranges tested, as described in the instructions above.
BuySellCCI uses a single parameter, requiring only 40 tests to
optimize. this makes it quicker to run than most two-parameter
systems, which typically need about 40 x 40 tests or more, depending
on the number of values you want to test. performance can definitely
be an issue as the number of tests goes up, and even single parameter
systems can be pretty slow with a large number of stocks.
in the FRAMEWORK CONFIGURATION section, try changing
equity_lookback_bars (how far back performance is evaluated during
optimization) and equity_lookback_frequency (how often optimization is
done). if you want, you can actually optimize these; possible
optimization settings are provided. be cautious in interpreting those
results though. I'd do it more for a quick sense of how things behave
than to necessarily choose the highest performing settings. at the
very least, test a variety of stocks and time frames with any settings
you arrive at, to make sure they're not a fluke.
try some of the other included trading rules, maybe starting with the
MA/EMA/DEMA/TEMA cross rules. hook them up and select parameter ranges
to test as described in the instructions above.
try adding your own trading rules, and experiment with optimization
ranges and equity feedback parameters.
try modifying the performance scoring methods, and adding your own.

// CUSTOM TRADING RULES - EDITABLE

/*
this is where you put the various trading rules you may want to test.
only one rule can be in use at a time. select which one actually gets
used by editing the framework function BuySellRule(), at the start of
the FRAMEWORK CONFIGURATION section.
all rules should set buy, sell, short and cover, in response to the
parameters passed to it and whatever logic you want.
your rule will be passed 3 parameters:
dynamic (true/false) : true if parameters are arrays, not just single
values; see ABOUT THE 'DYNAMIC' PARAMETER, below
p1 (number/array) : first optimization parameter
p2 (number/array) : second optimization parameter
p1 and p2 are the values being optimized on. trading rules can use
them for any optimizable purpose, MA periods or crossover thresholds
for example.
during optimization, the rule in use will be called multiple times,
once with each combination of p1 and p2 being tested. at this time, p1
and p2 will be simple numeric values, not arrays. once optimal
settings have been determined for every bar, the rule will be called
once more, to generate actual trading signals. this time, p1 and p2
will be arrays, each bar containing the optimal p1 and p2 value for
that bar.
ABOUT THE 'DYNAMIC' PARAMETER
not all AB functions can take arrays as inputs. for example, MA, TEMA
and DEMA can use an array as their period, but EMA can't. it's usually
possible to code an equivalent that can in AFL, but it may be slower,
or in a DLL, which I didn't want to depend on for this. this speed
difference can be big, since the trading rule is called many times
during optimization.
if desired, your rule can include both slower array-capable code for
use in the final signal-generation phase, and faster,
non-array-capable code for use during the many optimization tries. if
you do this, use the 'dynamic' parameter to know which to call. see
BuySellCCI, below, for an example.

/*After entering the formula just click on Optimize button in
"Automatic Analysis" window. AmiBroker will start testing all possible
combinations of optimization variables and report the results in the
list. After optimization is done the list of result is presented
sorted by the Net % profit. As you can sort the results by any column
in the result list it is easy to get the optimal values of parameters
for the lowest drawdown, lowest number of trades, largest profit
factor, lowest market exposure and highest risk adjusted annual %
return. The last three columns of result list present the values of
optimization variables for given test.
When you decide which combination of parameters suits your needs the
best all you need to do is to replace the default values in optimize
function calls with the optimal values. At current stage you need to

HOW TO USE:
Copy this file in your include directory or append it to
another file that You
use as "functions database".
"a" is the lowest value, "b" is the highest value.
EXAMPLE:
1. if you want to generate random between 1 e 100 (with
decimal values):
RandomNumber = Randomize(1,100);
2. if you want to generate random between 1 e 100 (with only
integer values):
RandomNumber = int( Randomize(1,100) ) ;
