I
think DT came up with a code to help find "Holes" . Basically they are
caused by your data provider. Yahoo data is free and sometimes you get what
you pay for, they may simply miss a day of data on a stock or report
incorrect data. If you are using QP2 this is seldom a
problem.......

Jayson,
just one quick thing while I´m workinf thru
your enlightening post:
Where may data holes as mentioned by you,
result from? If you have, say 10 stocks, making up an index and all of those
stocks contain data for, say, 5 years, where should holes take place? Or is
it if not all the stocks show the same amount of data?
Or is something else a potential reason? How
can I realize I have a hole?

Hello Jayson,
don´t ya worry!
You´ve already helped me a great
deal in understanding the "basix" of
Addtocomposite.
1./ somehow my indices have been stored
in -->markets-->market253 AND group 253. While
I understand the latter, I don´t understand the former. Is this a
MUST?<SPAN
class=678142113-24042003>
<SPAN
class=678142113-24042003>
<SPAN
class=678142113-24042003>I think markets 253 is equivalent to All your
stocks and tickers. I am not sure what you are doing but I tend to break
that group into watch lists for testing and explorations. For instance you
could create a watch list of Nas 100 stocks. This watchlist would contain
stocks that reside in the new list AND market
253........
2./ I used the "x" option for the field
code, figuring that would enable me to make a bar chart from it (since
OHLC are updated). But this is NOT the case. I get only. No way to produce
a bar chart as in HGS/QP2 from it?? I thought of generating 4 ATC´s (one
for Open, one for High etc.) but how to bring those together in one index
bar for each trading day :-((((<SPAN

<SPAN

Plotting your
ticker now will show the appropriate OHLC data. Unfortunately if you
have any holes in your data they may cause misleading candles. By dividing
the values by the number of calculations in each composite you can smooth
these errors. To plot this create a custom indicator

AB will
determine what sector (or industry in your case) the stock belongs to then
automatically plot the index for that stock. I use this approach daily to
compare the stocks RSI and the sectors or the stocks momentum and the
sectors or to measure the stocks correlation to the sectors
etc

3./ It makes me wonder that the
newly created indices (in our case the IM200´s) have to be updated EVERY
day MANULY(running the scan). Is there no workaround for this (i.e. store
the calculated day somewhere and onl update the LAST session as with
regular stock data??).<SPAN
class=678142113-24042003>
<SPAN
class=678142113-24042003>
<SPAN
class=678142113-24042003>The calculations needed require a look at your
whole universe. Just save your scan and run it... think of it as part 2 of
your daily update. It take but a moment. IMO this feature alone is
worth the price of admission to AB. I used to do all this work as a QP
scan then export to excel, sort, calculate and import to metastock. If I
missed a day I had to rewrite the scan to get yesterdays data etc, etc.
With AB the composite is re-created each day so if I miss a day, no
problem. If QP makes an adjustment, no
problem.
<SPAN
class=678142113-24042003>
<SPAN
class=678142113-24042003>I have one scan that creates all my sector
composites, all my industry composites, and several market breadth
composites. It takes my old P600 system about 2 minutes to do the work
then AB even sends them to the appropriate watch list for further
analysis. Super feature........

Re: [amibroker] Creating IM200 indices - JAYSON
Anthony,thanks for stepping in here.If I
may:1./ does Jayson´s SYM variable refer to the array part of
the addtocompositefunction. If so, why is it not put in parenthesis
(though this results in anerror).<SPAN
class=855470704-24042003><FONT face=Arial color=#0000ff
size=2>
<FONT
size=2>The line
<FONT
size=2>
<FONT
size=2>sym="~"+sectorid(1)
<FONT
size=2>
<FONT
size=2>looks at each stock you scan and places "~" +
the sector ID for that stock in its place. If,
for instance the stock resides in the Utilities Sector then AB notes
this and returns sym= "~Utilities". Addtocomposite grabs this
shorthand and Therefore the next line <FONT
face=Arial>
AddToComposite(<FONT
color=#000000>C<FONT
face=Arial>,sym ,<FONT
color=#ff00ff>"C"); <FONT
color=#0000ff> becomes
addtocomposite(c,"~utilities","C");
<FONT
color=#0000ff>This is repeated for each
stock scanned. addtocomposite then simply looks to the stocks sectorid
and places the data in the appropriate
ticker
2./ sym="~"+SectorID(1);// this does sectors for industry
groups useindustryid(0)I don´t understand Jayson´s remark here:
WHICH stocks does that include? Iwant to include all stocks
belonging to the same of the 200 industry groups.<SPAN
class=855470704-24042003><FONT face=Arial color=#0000ff

<FONT face=Arial

utilities, financials etc) If you want industry groups then replace that
line with

<SPAN
class=855470704-24042003><FONT face=Arial color=#0000ff

<FONT face=Arial

times??<FONT face=Arial color=#0000ff

<FONT face=Arial color=#0000ff

<FONT
size=2>Yes. the scan will create/update all 200
industry groups and store them in group 253 (the default location for
your Composites. You may also create watch lists of these
tickers to separate them. For instance I have a
watchlist with just the 12 sectors, a second for the industry group
tickers etc.... 5./ I added
"flag=16" which gave me an error. How do I have to specify if Iwant
to use addtocomposite in exploration mode?<SPAN
