Tomasz,
I would welcome your idea of a "nosync" flag.
Some of the uses I have for static arrays involve data that has no
relation to time stamps. Other uses are for saving temporary results
of calculations that are only needed once per parameter change on very
large arrays (200K) for special case backtesting. The backtests are
on one security in indicator mode with real time feed off. Speed is
important as it can take 20-30 seconds for one AFL pass today without
static arrays. It will take a while before processor speeds increase
30x.
In these cases the extra overhead of matching time stamps would not be
needed, and in the first case might actually create problems.
Best regards,
Dennis

Hello,
In that case it will work because timestamps are in sync.
In the future I may consider adding "nosync" flag, that will skip
any timestamp matching logic for such simple scenarios.
Generally speaking static array variables are designed to "do their
best" to synchronize to selected symbol even if there is no match.

array variables implemented!
Hi TJ,
Would you care to clarify comment d) below in the case of trying to
import output of one indicator from one pane to a second pane of
same symbol and same interval when the interval is Range bars.
Will it not work in that case?

Subject: [amibroker] AmiBroker 5.24.0 BETA released •Static array
variables implemented! (do NOT work well for tick/volume intervals!)
Hello,
AmiBroker 5.24.0 BETA is released now:
http://www.amibroker.com/devlog/2009/03/06/amibroker-5240-beta-released/
This is somewhat special beta because it contains only one fix and
introduces only one new feature: array static variables.
I decided to release this feature "alone" because the static
variable code has been completely rewritten, so in case of any
issues, it would be easy to revert to 5.23.

d) static array variables do not work well for non-time based
intervals (tick/n-volume/n-tick) because timestamps in those intervals
may not be unique (i.e. several bars may have same time stamp), so
time synchronization is not reliable.
