Jamp,
That's correct - a support level, once broken, commonly becomes a new resistance level. Commonly, not invariably.
I have no expectations - all I know is that Sanford is looking weaker now than it has in quite a while. Even if you take the optimistic view that the trading range is continuing, this stock has gone nowhere for over 2 years. During this time many NZ stocks have made significant gains.
So you have just bought - maybe you were feeling lucky, maybe you have picked the bottom to perfection, maybe you know something that others don't, maybe something fundamental has changed, maybe you are a true contrarian. Good luck to you - SAN owes you a drink or two.
