Market Selling off

It comes... finally.
4.27pm, DJI Future -116; FTSE -89;  HSI -680, STI -40 at 2975.

STI was selling off heavily today. As what the charts tells me as it hit major resistance last week. Market is down on concern over "China Slowdown and Greek concerns"--if you wanna find out why market down today from the news. To me, all the news are stories and are just props.

STI immediate support I'm looking at is 2950.
