I was trying to run the Autotrader program someone on these boards programmed and ran across the following: Activate "TWS API Active X and Socket Client". Since I don't speak Greek, I looked it up, but couldn't come to a clear definition. From reading threads on these boards, it seems that there are two ways ( or more) to connect to a data provider or broker and that the browser way is the slower and the direct (I presume a local program on my PC ala Java applet ?) is the faster way to direct connect to the data provider like E-signal, a broker etc. I know that the Autotrader program runs in conjunction with IB and assume that the API refers to a set of standards that IB provides for systems designers that runs via Java or Active X?? But I don't know where to find that activation button on my PC and there was no reference in the help file to comply with the request. Can you help me?
