取指標數據
通過獲取系統自帶的MACD指標數據，進行變色重建，實現起來非常方便，可以直接取到需要的數據。需要先建立指標句柄，再用CopyBuffer()函數取數據。
intmacd_handle?=0;macd_handle?=iMACD(Symbol(),Period(),12,26,9,PRICE_CLOSE);//取指標數據CopyBuffer(macd_handle,0,0,rates_total,macdBuffer);CopyBuffer(macd_handle,1,0,rates_total,signalBuffer);
填充緩沖區
生成自定義指標，其實就是填充緩沖區的過程，將指標線、柱圖、填充區、箭頭緩沖區數據進行賦值，就可以實現我們需要的效果。
在填充箭頭緩沖區時，需要更改箭頭的樣式，并且只是在雙線出現金叉、死叉時才賦值，所以還需要將0值位置設為空繪制區PLOT_EMPTY_VALUE。
??PlotIndexSetInteger(5,PLOT_ARROW,225);??PlotIndexSetInteger(6,PLOT_ARROW,226);??PlotIndexSetDouble(5,PLOT_EMPTY_VALUE,0);??PlotIndexSetDouble(6,PLOT_EMPTY_VALUE,0);
需要注意的是，采用循環遍歷賦值的方式，循環變量起始值在初始加載指標時為1，加載之后為prev_calculated?-?1，這樣在循環體內，即加載了所有歷史數據，也實時更新最新數據，不會重新計算所有歷史值。
//給緩沖區賦值,起始值intstart?=1;if(prev_calculated?>1)???{?????start?=?prev_calculated?-1;???}for(inti?=?start;?i?<?rates_total;?i++)??{//循環體??}

文華技術人員：
1樓指標注釋部分與執行部分混在一起了
您重新上傳一下 正常格式的源碼，我們分析看下。
另外1樓圖片沒有上傳成功，您可以在如圖位置上傳圖片
MT4指標和文華指標言語相差過大，需要聯系相關同事來進行修改。
