Re: [amibroker] Aux data fields

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 byte aligned, so 
you can not have odd number
of floats in the structure.
3. It would make it very difficult to write 3rd party plugins if quotation structure size was not known in advance
4. If you really want more fields - use different ticker (artificial ticker) and AddToComposite or use static arrays.

All in all, for all practical reasons it makes no sense.

Best regards,
