[amibroker] Analyze all stock symbols at endof day
Hi, My apologies if I have re-posted this but I couldn't find similar topics. After I get EOD data for all the symbols (about 1000 symbols), I want to run a AFL script on all these symbols and give a consolidate output. My AFL scripts gives a buy indication if price crosses 10-day EMA. I want a single output that lists all symbols that gave a Buy signal. Is this possible? thanks -bhakta
[amibroker] MIDAS from TASC
Thomasz,
Thank you for providing this useful code in TASC. It works well but
however I had a question: in using the indicator on intraday charts (1
minute) I noticed that when you enter a date in the pameter it is
actually taking the date - 1. Example: if I enter Oct 8, 2008, 18:26:00
it will actually plot the line starting at Oct 7, 2008, 18:26:00.
How it that? I ask because I am not to competent in AFL and could not
understand this by opening your formula in the editor.
Thank you for any help,
Carl

G'day all,
At the risk of acronym overload, is anyone successfully using the AB's
built-in DDE plugin with IBFX for forex data?
I know that my IBFX DDE is working because I can set it up fine in
excel. In AB, however, it doesn't get past the yellow WAIT status.
I have read the previous emails but they haven't really shed any light
on this.
Any suggestions would be most welcome.

Re: [amibroker] IBFX and AB DDE
Tomasz,
Using DDE makes no sense when there is dedicated plugin.
It could makes sense if one PC works in RT with ibc and with the plugin
and a second PC is used for formula testing.
It will be an easy way to dupplicate historical data nearly in RT on a
second PC.
Am I on the wrong track ?

When we are using auto analyser for signal generation, buy and sell signal appear properly but in live stream updatation we faced a problem that is signal arrow appeared but it is suddenly disappeared.How do i solve this problem?
Re: [amibroker] IBFX and AB DDE
Hello,
DDE does not work across computers so that won't work with DDE.
It will however work with dedicated plugin, if you just go to
File-Database Settings, Configure and specify different IP number there.
So again dedicated is better than DDE.

[amibroker] Custom Composite Index Problem
I have created a custom Index using AddToComposite. Here is the code that runs in Exploration: - Counter = IIf(IsNull(Close),0,1); AddToComposite( Counter * ROC(Close,1), ~MyIndex, C, 1+2+8+16 ); AddToComposite( Counter, ~MyIndex, I, 1+2+8+16 ); Index = 100 + Cum(Foreign( ~MyIndex, C ) / Foreign( ~MyIndex, I )); Multiplier = (100 + Foreign( ~MyIndex, C )/Foreign( ~MyIndex, I ))/100; Filter=1; AddColumn (Close,Close); AddColumn (Index,Index); AddColumn (Multiplier*100,Multiplier x 100); -- The problem is using the CUM function adds the daily percent change to calculate the Index. I wish to use the Multiplier to calculate an index where the previous days index value is multiplied by the Multiplier. The index should initialize as Index = 100 to start with the first bar. Its probably simple fix, but I can't get there. Frustrated, Todd K.

Hi, You may find the following document useful for some ideas (thanks to Herman): http://www.amibroker.org/3rdparty/IntroToAtc.pdf Additionally, be sure to study page 17 to ensure that your immediate Foreign usage of ~MyIndex within a single exploration is behaving as you expect.

[amibroker] Trouble with Equity function
Hello, i would like to use another definition of equity (as is being provided by AmiBroker) to use for position-sizing. Instead of total portfolio equity (cash plus value of open positions), I intend to use raimining cash balance PLUS value of all open positions but only with their respective sell stop levels (in the case of long positions, otherwhise: buy stops in case of shorts). For instance, if the remaining cash balance is 80.000,-- USD and I have a long position with a value of 20.000,-- USD on which I have a sell stop at 10.000,-- USD, then I would like to USE 90.000,-- USD for equity to use for my position size algorithm, for instance 2 percent. I find this more logic than using the day by day values of open positions. Has anybody out there modified AB´s equity function to achieve something similar? By AB support, I was directed to http://www.amibroker.com/guide/a_custombacktest.html but i have not enough expertise to write a code myself for this - I´m struggling enough with regular AFL. Thanks for any help on this! Markus
Re: [amibroker] IBFX and AB DDE

available for IBFX...anyone else using InterBank FX with DDE plugin?

[amibroker] Re: Custom Composite Index Problem
Thanks Mike. I had read that doc. And I did notice I had to run Explore a couple of times to get things to converge properly. My basic problem is I cannot use yesterdays Index times the Multiplier to get todays Index. Something like: Index = Ref(Index,1) * Multiplier This doesn't work and gives an error. Something about using an un-initialized variable.

Its probably simple fix, but I can't get there. Frustrated, Todd K.
[amibroker] Re: Custom Composite Index Problem
Todd, Index = Ref(Index,1) * Multiplier A few observations: 1. You should use Ref(..., -1) if you want the previous bar's value. 2. Uninitialized variable errors come from trying to use a variable that has not yet been assigned a value. In your example, if this is the first time you are assigning a value to Index, then the problem may be that you are trying to use a value (i.e. Index) that has not yet been defined (i.e. what do you expect to be in Ref(Index, ...) when Index itself has not yet been set to anything?). 3. Note that the values for an array are all set at the same time, not sequentially bar by bar: http://www.amibroker.com/guide/h_understandafl.html When trying to calculate current array values based on earlier values from that same array (e.g. current value is a multiple of the previous value), you will usually have to use looping code. Though, you may be able to use AMA or AMA2 to do the job for you. http://www.amibroker.com/guide/afl/afl_view.php?id=18 http://www.amibroker.com/guide/afl/afl_view.php?id=19 Mike -- In amibroker@yahoogroups.com, toddk63 [EMAIL PROTECTED] wrote: Thanks Mike.

[amibroker] Re: Custom Composite Index Problem
Ref(C,-1)...Oh yeah. Forgot. I meant what I knew to say. Thanks! These are exactly the hints I need. I'll give it another shot.

Use Code Check Profile function in Formula Editor to check whether your
formula looks into the future.

[amibroker] CBI - Trade Duration
I am trying to code custom backtester to create a chart of trade duration, from
the info available from:
for( trade = bo.GetFirstTrade(); trade ; trade = bo.GetNextTrade() )
{ ...
... }
I have not found a concept that works ... yet.
Any suggestion / code is welcome
TIA
