Steve,
Thank you for the reply.
Read me lists all technicals for completness and for advanced
usage. But if you looked one point below it says :
- new aqh.format file included in "formats" subfolder using new ASCII
importer commands to import and adjust prices from Yahoo. Compatible with
existing AmiQuote versions.
It means that the beta is set up so that it replaces (without
user intervention) existing aqh.format file so it uses new features
automatically and you don't need to touch anything at
all.
Every beta is set up so that you can simply accept the
defaults and these default setup suits 99% of users.
One comment: the automatic adjustment feature of course
affects new downloads / new imports only. So you need to
re-download
(or re-import) entire history to get split adjusted
quotes.

Subject: [amibroker] Re: ASCII
Import
Tomasz,
Thanks for the explanation, and the upgrade to take
care of these Yahoo! changes.
I'll explain what I 'thought' was confusing. Here's
the read me (which, incidentally, looks like it applies to File/Import
ASCII and not to Amiquote):
ASCII importer: support for importing unadjusted Yahoo data performing
adjustment on the fly:
new field ADJCLOSE - to read adj. close column from
Yahoo. Works _only_ in conjunction with CLOSE field. When both CLOSE and
ADJCLOSE are present in the ASCII format definition then importer calculates
split factor by dividing ADJCLOSE/CLOSE. It then multiples OPEN, HIGH, LOW
and CLOSE fields by this factor and divides VOLUME field by this factor.
This effectively converts unadjusted prices to split adjusted prices. Split
ratio gets locked once ADJCLOSE drops below 0.05.
new command $ROUNDADJ decimaldigits - causes
split-adjusted prices (see above) to be rounded to 'decimaldigits'
precision. By default no rounding is done.
new command $RECALCSPLITS 1 - (off by default) causes
that splits are recalculated by AmiBrokerby the algorithm that tries to
construct correct adjusted price, based on inaccurate information provided
by Yahoo.Note that Yahoo provides only 2 decimal digits in adj. close
field therefore the more adj. close approaches zero due to adjustements the
error grows. The option $RECALCSPLITS 1 is intended to address this problem
(at least partially).It works as follows:1. for each bar ratio
ADJCLOSE/CLOSE is calculated2. if the ratio changes in two consecutive
bars by more than 10% it means thatsplit happened that bar. True split
ratio is guessed by matching true fractionin the format of X/Y, where X
and Y = 1..9, to the change in ratios.3. Then true split ratio is used
to adjust all past bars until new split is detected.
new command $RAWCLOSE2OI 1 - (off by default) - causes
that OpenInterest field gets assigned CLOSE (raw close) field value
multiplied by 100
About half way through this I was wondering how I was
going to use the new '$RECALCSPLITS 1' command etc.! I gave up in alarm before
reading that this was:
Compatible with existing AmiQuote versions.
This is the way a non-programmers mind works

Steve,
I don't know what do you think is confusing.
New version of AmiBroker (4.46.1) just works with EXISTING
AmiQuote 1.55
exactly the same way as old versions did. No change in
operation is necessary.
The only difference is that when you download history from
yahoo quotes are automatically
split adjusted.

The new method of importing Yahoo! data seems confusing.
How does it relate to Amiquote? Is Amiquote redundant, or is a new version
on the way?
