GoodMorning Daniel I m tring now and it's OK I used the zorro's script "trade test" and I have bought and the I have sold one lot In the same time I was checking in the IG's web site (my private area) and the position and the order are the same that I have commanded with zorro :-)
Next step will be launch a z script :-)
in the istruction https://github.com/dan-lind/igzplugin you write: "Start Zorro and check if the Account drop-down-box shows IG as an available broker. Enter your login details, pick a script of your choice and press Trade."
maybe it's more clear if you specify that the "Login details" is not the first IG' account but that created for the companion API praticaly the same that peoplet have to use
post scriptum Sorry for my English, I suppose that there are many errors but I hope that The concept is understandable (also with the help of google translate :-) )
