[This was in another thread, but probably wasn't the best place for it since nobody answered ] I used the DDE link once about 2 months ago with ensign windows (out to excel pro 2000) to see if it really worked, which it did, but it seemed to be a little slow, i.e. the quotes would appear in ensign/esignal, but it would take 1/2 second or so for them to appear on the spreadsheet in excel. Was my experience indicative of the DDE link itself, or was the delay most likely introduced by ensign submitting the data to excel? Can someone who uses the DDE link with IB to submit orders please let me know if it is fast? I trade only volatile, pseudoliquid nasdaq stocks, so any slowdown between excel and TWS, whether it is due to the DDE link or simply computer-related (due to the extra processing involved in running excel) is unacceptable. My computer speed is no issue; it is fast. Thank you. PS - If DDE/excel are fast enough, does anyone know of a good source to quickly learn the VB code you need to create orders?
