请老师，高手修改，我是新手老是EA不听指挥，多谢多谢
Where are the statements for indicator buffers?
init() { SetIndex(0,DIFF0); SetIndex(0,DIFF1); SetIndex(0,DIFF2); SetIndex(0,DEA0); SetIndex(0,DEA1); SetIndex(0,DEA2); }See the Moving Average Convergence/Divergence, MACD (indicator) and MACD Sample (Expert Advisor)
能详细更改一下吗？我看不懂
DEA0=iMAOnArray(DIFF0,Bars,SignalSMA,0,MODE_SMA,0);是MACD中的慢线吗？
DIFF0=iMA(NULL,0,FastEMA,0,MODE_EMA,PRICE_CLOSE,0)-iMA(NULL,0,SlowEMA,0,MODE_EMA,PRICE_CLOSE,0);是快线吗？
1.3*(DIFF0-DEA0）；是MACD的值吗？

MacdBuffer[i]=iMA(NULL,0,FastEMA,0,MODE_EMA,PRICE_CLOSE,i)-iMA(NULL,0,SlowEMA,0,MODE_EMA,PRICE_CLOSE,i);and signal line (slow) of MACD
SignalBuffer[i]=iMAOnArray(MacdBuffer,Bars,SignalSMA,0,MODE_SMA,i);You can get value both of lines (indicator buffers) on each bar with function iCustom. As shown in expert adviser MACD Sample
