If you are already settled down into a market then it is advised that you should try to make a good go of things whilst you are there.
In the circumstance, where you are unable to work in that market or if you decide that it does not work well with what you are offering/selling then move market.
"The Move"
Once again, please think before you move because you may not be welcomed back into the other market if you leave.
To move market, you need to clear a few things up with the one you are in at the time of the move. Once you have cleared things up and are ready to move, you need to play out your ideas on your new chosen market.
If they work and your are happy with this new market, then by all means move to it.
