Hello,
You can easily write the formula that will execute for hours. Loop zillions of times
using FFT and you will kill everything. Even if you had 1000GHz.
If you are using real-time it is YOUR task to make sure that YOUR formulas
execute fast enough. AFL is the fastest engine out there, but you can kill the computer
even if you code in assembler. It is not AmiBroker problem but your FORMULA problem.
You need to go to Tools->Preferences->Miscellaneous and use "Display chart timing"
All formulas shipped with AmiBroker execute well below 0.1 second. This should be your target.
If any of your formulas need more than 0.5second this formula is not suitable for real-time
and must not be used. It has to be re-written properly or removed.
Best regards,
Tomasz Janeczko
