Yes, this is for 1.12. There is no difference between Weekend = 4 and 7.

If you see the "No Data" message, stop Zorro. Otherwise I'd leave that to you. We have Zorros running since several months without an FXCM API problem, but to be on the safe side, it's probably better to stop it and do the Weekend workaround.

When FXCM has fixed the bug, there won't be a need for Weekend = 7 anymore, but it won't harm either.
