这个多空箭头提示指标很好，就是存在bug 多头信号箭头没有问题，仅出现一次，除非条件再次满足出现。 空头信号会不断出现很多，并无法自动消除，只有重新加载模板才可以显示真实的唯一当时空头箭头。 期待群内MT4高手看看bug在哪里？谢谢 //+--------------------------------------------------------------------------+ //| 3 MA Cross w_Alert v2.mq4 | //| Copyright ?2005, Jason Robinson (jnrtrading) | //| http://www.jnrtading.co.uk | //| 3 ma conversion and Alert , David Honeywell , [email protected] | //| http://finance.groups.yahoo.com/group/MetaTrader_Experts_and_Indicators/ | //+--------------------------------------------------------------------------+ /* +-------------------------------------------------------------------------------+ | Allows you to enter 3 ma periods and it will then show you and alert you at | | which point the 2 faster ma's "OPEN" are both above or below the Slowest ma . | +-------------------------------------------------------------------------------+ */ #property copyright "Copyright ?2005, Jason Robinson (jnrtrading)" #property link "http://www.jnrtrading.co.uk" //---- #property indicator_chart_window #property indicator_buffers 2 #property indicator_color1 Red #property indicator_color2 Green //---- double CrossUp;
