我已经解决好了啊 现在这个版本可以用了 共享了
正好缺这个 看下
怎么购买后没办法下载？
扣完了金币为什么就是没有弹出下载窗口呢？要下载又要重新购买，太没有道理了啊。
我有源代码插件也改好了啊 有兴趣的加我QQ413794142谢谢

//
// This "indicator" calls DLLs to fetch a special XML file from the
// ForexFactory web site.It then parses it and writes it out as a .CSV
// file, which it places in the folder: experts/files so that IsNewsTime()
// can use that file to tell if it is near announcement time.
//
// It does this once when it starts up and once per hour in case there have
// been any updates to the annoucement calendar.
//
// In order for this to work correctly and synchronize with your broker's
// server time, you must enter the proper value for "TimeZone".This is
// entered relative to GMT.For example, my broker's server time is GMT+1,
// so I have the default set to 1.If your broker uses GMT+3, enter 3.
// If your broker uses GMT-2, then enter -2.
//

//2/14/2007:Robert Hill added code for using text objects instead

//
//2/25/2007:Paul Hampton-Smith for his TimeZone DLL code
//
//2/26/2007:Mike Nguyen added the following things (search text for Added by MN):
// -Connection test so that MT4 doesnt hang when there is no server connection
// -Fixed some minor syntax because was getting "too many files open error..."
// -Added vertical lines and vertical news text so that we have a
// visual reference of when the news happened.
// -Now supports and correctly draws two simultaneous news announcements
// -Added text to say "xx min SINCE event..." after the event as past
// -Clean up old Objects left behind on old news annoumcents

/*
IDEAS FOR ADDITIONS:
* A text lable of what the news was and when it was, e.g
"USD CPI m/m @ " at the top or bottom within the shaded area.
* Label the number of pips it went in its initial direction and how much it
retraced...of course you'd have to come up with a convention for measuring
movement.Or you could label what price was just prior to news then labels
the next two price exteremes.I think it would be nice to have the numbers
right under/over the candle that produced the extremes for whatever timeframe
you are in.
* Label the volume count for the candle that included the news in it...whatever
timeframe your in.So I could switch from 1 min. to 5 min. to 15 min.
timeframes and get different vol. counts for the bar that included the news.
