Terry or anyone,
In the help files it says:
Working with intraday and daily charts
If your data source supports mixed EOD/Intraday mode (such as
eSignal or Marketcast) you can use single database for both types of
charts.
This means your R/T
source can backfill daily data. For example,
QuoteTracker cannot do this. I don't think IB can either.
However if your data source does not support mixed EOD/Intraday mode
and if you want to have long daily histories AND intraday charts you
should consider running TWO instances of AmiBroker. One for EOD
charts and second for intraday charting. Both may use the same real-
time data source.
For the EOD with mixed
R/T this means you'll have to backfill the daily
history yourself using another datasource. I have a database like
this and I get the EOD history from Yahoo nightly. I also have a CSI database. This
one cannot use R/T because the ticker symbols are not
recognized by any R/T source and Alias does not work for
translating R/T, only EOD via tables in Amiquote (this
is from Tomasz).
So I opened two seperate Amibrokers one with the IB RT feed and the
other with the EOD data. I can get the EOD to update on a RT
basis
but it seems if I have to close it down for any time I can't get it
to fill in the gaps via a backfill. Do you have this
problem? If
so how do you fix it?
See above about backfilling
from EOD data source. Note: Mixed/EOD database means
you only have ONE SINGLE QUOTE for the current day. You do NOT have all the
minutes in the day here. It just reads the R/T and updates today's quote
"as if it were the end of the day".
Also when I do a scan with the EOD/RT up and running I get this
error message: Connected OK
Last Message from TWS:
APOL, 322, Error processing request:-'ReqHistoricalData': cause -
Max number of tickers has been reached
It seems your limit is
less than 100. Standard eSignal is 50 (you can pay for more). QuoteTracker
using Scottrade is 20. I don't know what IB limit is. If you Scan, you force AB
to try to get all the current data. This can be suppressed
in Prefs, but I don't think this is what you want.
In my TWS I have 97 stocks and 3 futures in total. So there are
only a total of 100 symbols running in TWS and I am trying to get
the stocks to update and backfill in AB not the futures.
Thanks
Eric
