STI Support

STI dropped more than 40 points and rebounded a little now with 38 points down still. The support level for STI:

First level 3140, a minor support level, then
3120, a major support,
3180 is the resistance level now.

What's in my head now is what will be the impact on STI tomorrow if US market down, see if DOW dropped over 100 points? err... 3120 is so important to watch now.
