I thought Zorro was based on the FXCM TS feed? So one should follow the other. It didn't open the trade because there was something wrong with the Zorro platform, not the script/system.

I fully intend to back test everything thoroughly before I trade live so it is no problem. If something doesn't back test right on mt4 then I will not be trading it live. In most occasions I have found that a profitable system produced with the help of Zorro trades well with mt4 as well, which is encouraging.

When Zorro is more robust for trading I will probably make the switch.
