RE: [amibroker] Static variables

["Herman van den Bergen" <psytek@xxxxxxxx>]

You 
may be able to prevent this problem by "disabling" the first 3 writes to disk, 
this in effect would ignore the first "Apply". Regular refresh cycles should 
execute code only once. with changing data or time.

You 
can also read the time (seconds) and do not allow writes within the same second, 
you copy the time to a static variable and unless it has changed you do not 
write to disk. This is a technique i use in some code...however depedning 
on what you are doing a second may be a long time. With high volume stocks, 
those giving several ticks a second you can count ticks and only allow writes 
when (Seconds OR TickCount) has changed. Not perfect i know...but since data 
doesn't change between ticks you would never write the same data to 
disk.

  variables
  I tried some time ago to write trade signals to 
  disk in real time, but got multiple writes. I had both interpretaion window 
  and tooltips closed. This made the EOD vesion work OK, but not real 
  time.
   
  Problem was that I still had multiple writes for 
  each operation I wanted. ... I guess the writes were with each tick (time base 
  was 1 min) in that bar ... or some other cause...
   
  The question I have, can Static variables help 
  eliminate this problem? Any other way?
   
  Thanks
