I tried it with the Z Strategies. I think these use the standard AssetsFix? I'm running Windows XP, and the AssetsFix is under C:\Documents an Settings\Username\Zorro\History

I didn't try yet, but isn't it still possible to edit the MQL4 Code as it was with the old Zorro Bridge?

Ok, it is possible. I solved my problem by adding

if(Asset == "NAS100") return(".USTECHCash");
if(Asset == "SPX500") return(".US500Cash");
if(Asset == "US30") return(".US30Cash");
if(Asset == "GER30") return(".DE30Cash");
if(Asset == "UK100") return(".UK100Cash");

at line 68 in the MQL4 file right under "string assetFix(string Asset)

Ok, but this does not explain why the symbol in the asset list is "NAS100" and not ".USTECHCash" as it should be. Check your z.ini file - maybe you're using a different asset list?

It's a clean and recent install of Zorro. This is the z.ini:

NFA = 0
FXOnly = 0
MMax = 100
Phantom = 1
Hedge = 5
Weekend = 2
Verbose = 2
BrokerPatch = 0
Preload = 0
AssetList = "AssetsFix";
Cancel = 0

Can you then run the following small script? Just for making sure.

function run()
{
assetList("AssetsFix");
asset("GER30");
printf("\n%s => %s",Asset,Symbol);
asset("NAS100");
printf("\n%s => %s",Asset,Symbol);
asset("SPX500");
printf("\n%s => %s",Asset,Symbol);
quit();
}
