thanks jcl. When I searched "log" from MT4 Data Folder, it's all easy to see that those trades were not opened because of "invalid trade volume". This time I've uploaded part of MT4 trade log which corresponds to the interval of "Z5demo.txt". After srolling down both "Z5demo.txt" and "20140512.txt" to the bottom, I've two questions. First, what does "invalid" mean? Dose it mean the volume Z5 intended to trade exceed the balance in my account. Second, Zorro's messages show that Z5 want to trade EUR/CHF at volume of 5, 3, 3 lots respectively while MT4 shows only 0.05, 0.03, 0.03. How can this happen? Basic info: balance 4898.24$ when starting to run Z5;leverage 1:100. Since I run Zorro and MT4 on a VPS, timezone on the VPS is GMT+8, my local PC is UTC+8.
