Hi Bruce,
Here is what I do:
1.Tools>Preferences>Intraday>Realtimechart refresh
interval>set to zero, this collects IB snap shots fast as possible.
The last time we had a fast market I had about 12 data points at the same time
stamp. That’s .00.
2. Forget about any type of back fill, just keep the computer on
all the time.
3. Go to a larger “bar” frame. I use range bars and
track a hand full of instruments, just adjust the tick size so that all my
charts are set to a range of $100 value. Stupid but simple!!
4. If for some reason you need data, collect up to 180 days under 1
minute setting, go back to tick and presto charts are pretty close. Sure I have
some range’s not perfect.
Hope this helps,
Any other Q, feel free.
JG

Subject: [amibroker] IB and volume
charts
I did a search on how to get consistent volume (number
of contracts) charts. I use IB for data, I know IB
doesn’t give true tick data, only snapshots, I know it’s data is
considered inferior.
Is anyone getting useable vol charts out of AB, my
intent is not to put AB down, I just haven’t been able to get reasonable
volume charts out of AB.
I currently use Sierra Charts and they give great
tick/volume charts. Backfills no problem, rock solid.
What settings should I use?
Backfill = 5 days
(database settings) Base time interval = Tick
Number of bars = 10000
I really want to be able to use AB with data from IB if
possible.
Thanks
Bruce
