your computer can handle. The limit is the HARDWARE you have (actually RAM

And I told you - it costs $4800 if you want to have it implemented your way.
If you want to pay for custom programming we can

Dollars and cents aside, i would like to understand the criteria that

Here is the case that i am trying to understand.
My AB has # o fbars 5 in base interval 1 minute
The data feed comign in is a tick level data feed.
Questions are

Hello,
1. Data are stored internally and externally in the base interval you specify
in the Database Settings.
If you have chosen 1-minute - it will be 1-minute, if tick - tick.
So whatever you choose - it is used.
2. Yes it uses FIFO.

And this is my biggest pet peeve about Amibroker:
If I have the disk space available, Amibroker should never, ever, EVER
just silently blow away my historical data because of some arbitrary
system limit like 500,000 bars or 1,000,000. If I want 20 million
bars historical and I have the disk

Do you ever try to import all of your 5 seconds data?
I have few years of forex tick data and for example I was able to
import a currency pair including 6 million of lines without any
problem into AB with ascii importer.
So, simply try it...

Hello,
Why don't you move to Metastock that has 65000 bar limit ?
The truth is that AmiBroker is the most capable in this area because
it stores way more data than other softwares. Also, by changing the registry
limit you can set it to any value you need. The limit is not the software but

Exactly. It simply works - no hard coded limit,
the only limit is your hardware (the memory you have on your system).
With 64 bit version the limit is 1024 Gigabytes of RAM (Windows x64 limitation).
The default 50 is to protect AB from the beginners trying to enter some
absurd numbers

Sure, I can import whatever I want into one symbol file. But I do
this up to a point just so Amibroker doesn't replace my old data with
new data coming in.
What I have to do is chop up my big symbol data (like tick files) into
much smaller files so Amibroker can handle the processing of the
E-minis are future contracts. They have less than one year of history and only
3 months of high activity per each, so you don't
need to store *years* of data even if you store in tick frequency.
If you want to backtest e-mini strategy you should switch between contracts

This isn't even a major change. It just removes the direct
relationship of per symbol data on disk to the amount of symbol data
Amibroker processes.
I will tell you something: you have NO idea, absolutely NO IDEA, if it is major
change or not.
As far as AmiBroker internals are considered

I believe the database limit is set to 500,000 but can be changed in
the windows registry. TJ has mentioned this in a previous post here,
somewhere sometime.
