Hi,

I am trying to use one formula file to generate multiple, distinct equity lines.
The idea is that I will just change the "apply to filter" in Automatic Analysis
and run the backtest while not changing the pointer to the formula file.  Each
time I run the backtest on a new filter group, I will create a new equity line
that has a label that reflects the group was being filtered for that particular
backtest.

So if I selected a group called "XYZ" for a formula file "ABC", on running the
backtest the equity line might be called "~~~EC_ABC_XYZ"

It is easy enough to create a custom-labeled equity line on a one-off basis, but
I want to make this more flexible by referencing whatever group I have decided
to filter with in Autmoatic ANalysis.  The article I used is here:

TO get this to work, I need to figure out how to obtain the name of the group
that is being filtered.  I tried Name(), CategoryGetName() etc and they don't
seem to give the right output.

Is there anyway to set the "Apply to filter" group programmatically within AFL
rather than having to click the buttons in Automatic Anaysis?

I have a lot of strategies that I would like to run on a daily basis.  Is there
some sort of batch processor that I can set up to run them?

They work the same as OHLCV arrays.

You can write to them, but what you write is NOT stored to database.

These are built-in price arrays and in order to protect from modifying quotes by mistake

you are writing to temporary runtime copies of OHLCVA1A2 arrays.

 

In order to actually write to database you need to use AddToComposite or COM or ASCII importer.

Nick -

I'll take this since I'm here and curious about something.  I saw that
Keith referred you to BoilerPlate.afl (thanks Keith) on AmibrokerU.  Did
you search for info about a "batch" manager and not find it there ?

I believe that I'm seeing a search issue on that site related to certain
article summary headers not being indexed and am looking into it.

Anyway, there is a article and video about Batman - a batch manager that
Fred Tonetti wrote some time ago.  It is in the Free Presentations menu
section under Free Library.  There is also a download link, although the
ZIP is also in the file group of this board.

It should do everything that you want and probably a little more.

-- BruceR

P.S. Also saw your note asking how to get the Watchlist name.  If I get
a chance later, I'll do a short article about a utility function I wrote
called GetFilter.afl that does that and some other things.  I never
thought anyone would need until now.

If Tomasz was designing a new language, then this discussion might have been
fruitful. And I might even support one of the well thought suggestions. But the
simplifications suggested by scourt2000, modified by Mike and supported by
progster provide a very complex picture that frankly are a lot more confusing
and less functional than the 2 two functions StaticVarSet and StaticVarGet.
Let me explain what i mean. The declaration static in C++ and other language of
the same genre (java included) has two properties. First is Scope, Second is
persistance. In terms of scope, it is within either the function, the class or
file scope that it is declared. Outside of that it simply doesnt exist. The
Second property is persistance. static tells the compiler that the
variable/class member still holds its value even if controll is passed out of
scope. So the value persist next time when control is in scope again. Now Mike's
suggestion is about permission, which is third dimension and isnt a property of
static. It specify who/what has permission to acesss the variable's value but it
doesnt say anything about scope or persistence.  To cater for all of these, then
you must have something like this:
Global public static xyz;
Not only that, Global by default should not have anything bigger than a file
scope. So we need to define xyz as
Extern Global public static xyz if we want to access it from another file. Now
you might say you can simply it by excluding mutually exclusive combinations.
But That is where what we'll have to begin with.
AFL is a script language, it is not object oriented and there is no instance
that anything can be private to deny unauthorised access.
The original suggestions was ambiguous, the additional suggestion doesnt really
clarify that, but it does create another way to make it more complex, And to
make Mike and Scout's approach unambiguous we need to go the extent of Extern
Global public static..... and perhaps more.
On the other hand, StaticVarGet is a function which allow us to bypass these
problems. It also has two additional advantages
1. The argument, hence the variable in question, can be gotten through string
concatenations programatically.
2. The function can be accessed through dll - a big plus for portability and
versatility.
My conclusion is that StaticVarGet is still superior and easier to understand
than what were being suggested.

Are there ways to control cash after a position is closed via sell, and not
applystop
e.g. If the sellprice is at the open, the cash is available to Buying on the
same day. But if the sell is at the close, the cash is not available until the
next day.
Looked at SetOption("ActivateStopsImmediately", true), it seems to work on stops
only.
Cheers
Paul.

Haven't seen that built into AB yet.  A feature request for vector-oriented
interest rates exists.

Custom backtester code can read your yield series and add interest to bo.Cash in
a bar loop.

OK, i think i know why the confusion: AUX1 and AUX2 are not formatted like a reserved word (like Close, Sell, etc) in the editor. They look like non-reserved words. However the syntax check does not flag them down as uninitialized variables so the are reserved variable names.

Is it possible to format/color them like other reserved keywords?



Many thanks,

THANKS
in advance

Looks simple but I cant do it

Subject: Re: [amibroker] How to use AUX1 and AUX2?

OK, i think i know why the confusion: AUX1 and AUX2 are not formatted like a reserved word (like Close, Sell, etc) in the editor. They look like non-reserved words. However the syntax check does not flag them down as uninitialized variables so the are reserved variable names.

Is it possible to format/color them like other reserved keywords?



Many thanks,
herman

They work the same as OHLCV arrays.

You can write to them, but what you write is NOT stored to database.

These are built-in price arrays and in order to protect from modifying quotes by mistake

you are writing to temporary runtime copies of OHLCVA1A2 arrays.

 

In order to actually write to database you need to use AddToComposite or COM or ASCII importer.

Subject: Re: [amibroker] How to use AUX1 and AUX2?

ahh, so they can't be assigned values, or be read, like we do OHLCVI fields? Thus, i gather, these fields cannot be used in a loop?

AUX1[b] = 999;
MyData = AUX[b]

I have a host of other uses, like storing real trade information so that these can easily be accessed and plotted - with having to compare DT all the time.

Thanks for the reply,

Hello,
Aux1 and Aux2 fields are intended to be used as:
1. Storage for extra quotation data such as bid/ask figures
2. Storage for other data such as trading volume expressed in dollars, volume-weigted average price, etc
3. Extra fields for AddToComposite/Foreign (use "1" field ID for aux1 and "2" for aux2 in Foreign/AddToComposite calls)
You can store values to those fields either using ASCII importer or
using OLE or using AddToComposite
Example:
AddToComposite( array, Name(), "1") ; // store array to aux1

any AUX1 and AUX2 users out there?
As is often the case some very useful new features sit on the shelf for a long time before people start using them, simply because they are not documented for the simple user. Tomasz, please give a sales pitch as what we can do with the new array expansion - its a waste to let it go to waste :-)

I can't find any examples on how to use the two new AUX1 and AUX2 fields. Can anyone give an example?
When working with the current ticker, how do i assign a value to one of these fields? How do i read it back?

Dear afl experts

Please look into this matter and code an afl for me

Conditions
1.use of heikin ashi candles
2.use of an envelope-bands(somebody told me these are WMA34 hi-lo bands)
3.use of a linear regression line with trend color change
4.overlay of pivots or volatility levels(cant make out)

trade entry happens as soon as price crosses above the bands and trend line or
directional indicator line with color
trade exit occurs on price reaching next pivot or volatility level
stoploss for long is on some recent low

short trade occurs as price moves below directional indicator line when it is
red in color, and as price comes below the bands.

Hello,

I would like to decrease Myparam of 0.25 on each clic inside the red button.

I complicated with static var but Myparam comes back to 5 as it is declared at
the beginning of the formula.

How to decrease a var with a GFX button ?

To give an idea of what I want to do , once this point solved, my next step will
be to increase of 0.25 the same Myparam with a Plus button to adjust a Fibonacci
step. I will add Fibonacci code at the very end.

AB parameters windows lacks some ergonomics in real time.

I draw the buttons in the upper right side, after the bars, as quote marker will
not be activate.

Thanks for the help

Best regards

Are you talking about a portfolio equity curve or the equity curve of an
individual security?  Unfortunately, I think equity() only works for individual
securities, not portfolio equity.  I have been looking into the same issue with
respect to portfolio equity, but am stuck as well.
