Hi DdlV

I haven't yet approached the broker about this. Before I do that, I would like to have some more evidence that these ticks are actually coming from the broker. While I am keeping an open mind about the source of the problem, I think that it is more likely to be a bug either with the script (unlikely, since no such ticks are evident in the backtest), my own set up (although I have reproduced the issue on two different machines with different installations of Zorro - both V1.42) or with the communication between MT4 and Zorro.

Thanks for the workaround jcl, I'll give that a try.
