iCustom调取返回 2147483647，怎么才能正常返回
你这个代码太长了我就不看了，直接给参考建议
去检查指标的初始值，可以给它一个初值的空值/0，那获取的指一般就对了。
指标有其他问题另说，不在讨论范围自己去改自己的指标就是了。
你應該接貼上原碼 標示出你要的問題
這麼長 看不懂 也不知道你要調的是哪個東西

仅仅是调用 iCustom， double val00=iCustom(NULL, 0, "zlwboxs",3,9,1,1,1); 应该还是指标的问题

開啟數據視窗 將由標定在要調用的K線位置 看看是不是你要調用的數據
這是觀察數據最直接的方法 有可能跟你想調用的佔存位置錯的
代碼一推的錯誤 想幫你解決 還要先排錯
你還是附上能用的代碼在弄吧
你這樣貼代碼 網管的很快就會把帖刪了的
我在网上找的一个指标，图形都可以在图表中显示。根据这个指标做EA，通过iCustom调取返回 2147483647。请高手帮忙给出一个解决办法能获取到正常返回值。不胜感激
