Mike,
By default, the "Local Data Storage" for PremiumData is turned off. I enabled
it and the duplicate symbol data and information seems to save to the local
database. I did quickly notice that by switching to local database from the
Metastock plug-in that only the symbols I've previously l
David,
Keep in mind that if you use a local datasource, your PremiumData updates will
not be reflected going forward. You will have to switch back to Metastock mode
to receive the updates, as per their website: "How can I increase the scanning
speed of AmiBroker?" http://www.premiumdata.net/su
David,
The code provided in my earlier post, below, works fine for me. Though, I've
only tested it on the trial version of AB, so the new tickers do not get saved
to the database (AB trial prevents that).
After the Scan, the new tickers are definitely populated with data and render
correctly
I figured out how to get the symbol duplicating code to work. Both the AFL
code that Mike posted and the javascript that I later posted work. The issue
is database settings. PremiumData is setup using the MetaStock plug-in and for
some reason setting quotes through ActiveX does not work when
I've been unsuccessful in filling a duplicate symbol with quotes from a
source symbol. I could not make it work in AFL, so I reluctantly
switched to javascript and I still cannot get quote data into a new
symbol. I guess I'm too close to my code because I cannot see what is
wrong. Can anyone see
Excellent Mike! Great suggestions. However the results of your modifications
is similar to the results I was getting before. The code produces duplicate
symbols with no quote data. Something is still not quite right with copying
the quote data from the source symbol to the new duplicate symbo
Thanks Mike, I appreciate the time you've spent thinking about implementing
multiple systems and avoiding duplicate symbols. I originally went down the
path of trying to use one symbol per market for 12 models and my system logic
got out of hand. Using a separate backtester run for each model
Try using DateTime instead. Also, the property is OpenInt, not
OpenInterest. Finally, rather than entering all the tickers manually,
just run a Scan over a watchlist of desired tickers.
e.g. using a simplified version of your original post:

Hmmm. Let me test my assumptions here:

Those two quotes sound to me like you have
1. one uniquely name
I'm already using a uniquely named watchlist for each model (in fact, I think I
got the InWatchList idea from you Mike). I'm not sure I understand how putting
the same symbol in multiple watchlists would work with multiple models. If I
put the same symbol name in two different uniquely n
Using OLE objects in AFL, what is the Date parameter format passed to the
Quotations.Add() routine? I've tried DateNum values, DateTime values, and
strings of Year + "-" + Month + "-" + Day. I've been unsuccessful in adding a
quote to a new Symbol created with Stocks.Add().
Here's the relevan
Hi,
Why, exactly, do you want to duplicate the symbols in the first place?
Why don't you just add the same symbol to multiple watch lists? If you are not
actually changing the underlying bar data, I don't see why you would want to
duplicate that data.
If your logic is dependent upon parsing th
I've attempted to code functionality to duplicate symbols using the AmiBroker
OLE interface. In my test code below, 2 symbols ($A0 and $CA) are attempted to
be duplicated into symbols $A0_2, $A0_3, $CA_2, and $CA_3. The duplication
process entails:
1. adding a new symbol
2. setting
13 matches
