Connecting a Delphi App to NT - best option?

[KayWarner]

Hi Guys,

Thanks for reading the post.

I'm looking for a little bit of advice really on how best to connect a Delphi application to NT.

Obviously i have been on the Forum and found lots about Stream.IO, StreamWriter, StreamReader & MySQL, and now i'm a touch confused.

I was wondering if any of the more exerienced of you out there had any advice on which to use?

The model i have written needs the average price of the previous 6 bars. it's result will be a single price.

I could compile it as a .dll also.

Hello,

Thanks for the forum post and welcome to the support forum.

Its best to use our API for this use. Please see here for information on how to use this in your external application.

would you suggest using;

FUNCTION Last(instrument : pAnsiChar; price : double; size : integer) :
integer; stdcall; external 'NtDirect.dll';

from within the model?

Hello,

Great to hear you found this. I love it when the community works together.

I'm not familiar with the layout of Delphi, however this would be where I would start yes.

Good luck!
