How to trade the news.....?

i've been having this problem trading most news. I read and understood todays expected news (GBP - Trade Balance due 4:30ET), i had the 1min & 5min charts open and expecting the news from http://news.efxnow.com/en/commentary/index.html (it came in late though).
The thing is that at exactly 4:30am, there was this spike (-20pips) that i just couldn't get into (viewing the 1min chart) before that time. Is there really a way one could know 1-2mins before the news the exact values of a particular news?

I was able to lock in about 15pips though (waited for a little retracement on the 1min chart)...but i strongly believe theres a way to know these values just b4 they come out.
I would have attached the charts for better understanding, but i really dont know how to filter the image and paste it...all i do is PrintScr(my whole monitor screen).

Hope to get a very good (tested and working) methods of getting into the news trades well.

there are some methods involving news trading. one of them is Burger Straddle Script
Hope this helped

Thanks alot semar. I got the script, read the thread, applied it but still don't know how it really works. May be bcoz i'm not too familiar with MT4, i use and love fxaccucharts from FxSol......really don't know what to do now

News sometimes 'leaks' before the announced news time, making price move. I also suspect it leaks only to the big institutes/brokers, etc.

Other reason could be that the big players pull out just before news time.
