试试吧（它现在在我的终端上显示了我想要的许多蜡烛）：candlebreaker_1.mq4

它现在对我来说工作得很好。

请注意。

[aiwanun]

大家好，我有一个问题，我的MT4不能显示在图表上了，MA，RSI，WPR蜡烛，它发生后，当我安装了一些天前的MT平台再次？ 任何人都可以帮助

[tfi_markets]

tfi_markets:
嗨，ProCoders。

我目前正在使用Autotrend Forecaster指标。

我写了下面的代码，但EA没有打开交易。

谁能看一下？

提前感谢您!

MT4在日志中只显示警报。

MT4在日志中只显示警报。

那么问题就出在你写在EA中的条件上。

检查 这些条件是否评估为真

[Thierry F.]

编码员们好。

我感到非常惭愧，因为这是我第三次询问警报功能。

我想在直方图的颜色发生变化时得到一个警报。

就像平时一样，我把指标缓冲区相互比较。但是这一次它不起作用了。

缓冲区工作得很好，我的比较函数也是正确的（在我看来）。

所以我认为这一定是个小问题，我希望有人能帮我解决。

提前感谢。

那么问题就出在你写在EA中的条件上 检查条件是否曾经评估为真

嗨，Mladen。

谢谢你的建议。我重写了一下代码，将条件 "强制 "为真/假。现在它是卖出，但不是买入。请看下面的代码。

if(openOrders<=0)

{

// AutoTrendForecaster

double AutoTrendup=iCustom(Symbol(),0, "AutoTrendForecaster",TMperiod,Intensity,SL_distance_pips,0,bar) 。

double AutoTrendup_prev=iCustom(Symbol(),0, "AutoTrendForecaster",TMperiod,Intensity,SL_distance_pips,0,bar+1);

double AutoTrenddown=iCustom(Symbol(),0, "AutoTrendForecaster",TMperiod,Intensity,SL_distance_pips,1,bar);

double AutoTrenddown_prev=iCustom(Symbol(),0, "AutoTrendForecaster",TMperiod,Intensity,SL_distance_pips,1,bar+1);

//+------------------------------------------------------------------+

//|买入

//+------------------------------------------------------------------+

bool buyCondition = false;

如果(AutoTrendup>0 && AutoTrendup!=EMPTY_VALUE)

{

buyCondition = true;

}

如果 (buyCondition)

{

OpenBuy()。

return(0);

}

//+------------------------------------------------------------------+

//|卖出

//+------------------------------------------------------------------+

bool sellCondition = false;

如果(AutoTrenddown>0 && AutoTrenddown!=EMPTY_VALUE)

{

sellCondition = true;

}

如果 (sellCondition)

{

OpenSell()。

return(0);

}

}

谢谢你的帮助!

不管SetIndexEmptyValue() EMPTY_VALUE不是==0，而是2147483647。另外，你在那段代码中有重绘的问题，你必须先把它清理掉

[Triip]

拜托，谁能修复这个指标，让它在图表上显示警报（已经在）箭头，而且它应该只在第一根蜡烛收盘高于/低于EMA时发出警报。

请看这个：https://www.mql5.com/en/forum/general

将快速平均线周期设置为1，然后它将与价格越过移动平均线（slo ma）的情况相同。

[Thierry F.]

非常感谢你，没有你的帮助我无法解决这个问题。

(ps.代码正在工作)。

祝你有个愉快的一天
