I'm trying to build an exploration that would store that bars calculated
support/resistance value in a custom array. Is this possible?
I would really appreciate any samples or pointers.
You don't explain exactly what you are after very well... but it's very doable.
Sounds like a job for static arrays so you can access them from outside the
exploration.

Hello,
1. You need to conserve memory. That is paramount importance. Not because of
RAM, but because of CPU CACHE.
Anything that exceeds CPU on-chip cache size runs 10 times slower.
2. On 64 bit systems there are strict guidelines for alignment for best
performance - the structure needs to be 8
I want to store custom values in an array that can be used to display in an
exploration. I guess the problem with my code is that the getSupport function
doesn't create a support array (I'm not sure how to do this)
Here is the snippet of the code to clarify what I'm trying to do:

Are you using 5.27.1 (*NOT* 5.27.0) ?
I can't reproduce that with 5.27.1.
What data source you are using ?

I am importing around 2,900 ascii files daily; usually it takes around 30-40
seconds if my memory is right; here with version 5.27 alpha it is more than
dubble this time, around 2 minutes.
Just wanted to notify that.

Appologies. I managed to reproduce that.
Actually it happened not when month has 31 days, but when last
day of the month (any length) was a trading day.

Hello,
The time it takes to import should be exactly the same as long as they are
imported in same order.
The order is critical, because if you import newer first and older later it
leads to re-sorting of the array,
while when you import older first and newest later no resorting is needed.

Great but this does not help. As I wrote - if you want me to check I need
actual files you are importing.
The speed is identical as soon as you work on converted database.
If you are loading the database for the VERY FIRST time since upgrade, it will

Thx for your reply. Would please explain the difference between fundamental

fundamental data fields are scalar? If so, does it mean that we would never

Hello TJ,
I've just tried out the "Pad non-trading days" feature in 5.26.5. When
conducting a cycle analysis on daily data, it's important to account for all
non-trading days and this feature is a step in the right direction.
However, as discussed in an earlier email, when adding the non-tradin
Hello,
It is fundamentally flawed idea to have fundamentals along with quote arrays,
simply because it would be tremendous waste of space, since funamental
data change only once a month (most frequently) and not every tick or every
second as prices are.
So historical fundamentals need *separate*
I can ensure you that it is much better than what you suggesting.

I'd suggest you look at the AB library. I see a number of hits searching for

First your backfill with IB and 'sec' data will be very limited. What I do
is change the database settings to 1 minute and then download data dependent

If you're coding in Visual Studio, set your breakpoints where you want in you
source, have the debug build of the plug-in in the appropriate Amibroker
directory and set the Executable to be the Amibroker program -- Broker.exe --
and start debugging. You should break on you breakpoint.
