Qzeus didn't trade today, is something wrong?

No. There is nothing wrong. Whatever it shows on the chart is exactly what it should be doing.

Qzeus will not trade every day, because not every day contains a high probability setup. There are other strategies that trade much more often, that isn't what Qzeus is designed to do.

Qzeus is designed to be slow, and boring, and make money. That's what it does. It may only trade twice in a week and this is perfectly fine.

If it's on the chart, and you can scroll back and see it trading previous days, then it is working perfectly fine and it just didn't trade today. That's all. It's working fine.
