I am not sure how to help. I have not used bread yeast, I have used purchased yeast for brewing. For the first day or so I normally use a blow off tube, befor the airlock. This allows me to let the excess foam to escape without making my air lock dirty. The bucket my blow off tube is in has a solution of vodka and water.
If your yeast is doing what it should it should be moving, if even just slowly. Your container is a lot smaller than what I use though. You might want to check the seal on the bottle, perhps your Co2 is escaping and not going through the airlock.
