I got the newest version of IB Gateway, necessary Asset subscriptions with IB are in place. Moreover, Multicharts .net downloads the prices from that same IB Gateway just fine.
I invite you to take your favorite asset list and see for yourself:
function run()
{
NumYears = 10;
assetList("History\AssetsMinutes.csv"); // load asset list
while(loop(Assets))
assetHistory(Loop1,1);
quit();
}
Seems to be a problem with Zorro after all.
