TJ,
for us non-techies and non-programmers, those who simply want to trade, the whole 64 bit issue (mess) is utterly confusing and frustrating. We need a clear, comprehensive, and official opinion from AB on where we stand and how to set up AB for optimum performance. Contrary to your opinion this is, for the silent majority, not simple. For example:
- Why do we have AB64?
- What are the advantages of using AB64?
- What are the limitations of using AB64?
- Is AB64 of any use to real-time traders using real-time data?
- Is the greater memory range of V64 used by AB32?
- How do we install AB32 + AB64?
- Does AB32+all Plugins run under Vista64?
- It seems you are addressing programmers and not traders...What does it mean: "You need 64 bit compiler to compile your own plugins." If this is so simple wht doesn't AB do this for us?
9. What does a 64 Bit Vista user have to do to maintain ALL Amibroker capabilities?
10 we need to run BOTH AB32 and AB64 to enjoy all AB features?
11 Do we need two partitions... this has been mentioned a few times.
12 Do we, or do we not, have to fiddle with the UAC?
... Other 64 bit users please feel free to add your own questions here ...
Contrary to the general opinion that setting up AB for optimum performance is simple and easy this is, for most "Traders", not the case. We want to trade not become techies. I already spend a lot of time browsing, searching, emailing, buying hardware, changing orders, printing notes from many places, ... If I need another two week of this headache I'll chuck AB64.
Best regards,
herman
