RE: [amibroker] [Repost] How to do long process run one time only ?

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

If you work EOD you could try to save the data in tables using the OSAKA DLL and readit only when you need it. Do a search for ASAKA and you'll find some examples.

 

My first approach would be to streamline the code, you can use DebugView to see where the time goes.

 

best regards,

herman

I tried something like that without success.
I will try once again.

I tried also.
I dont know VC++.
I have Delphi 5, but they are nothing  ready to use.
