MACD_histogram indicator alerts to mail
logart89:
Hello, this indicators that comes with mt4 when you install it is nice for finding Divergences, it displays a sound alert everytime it finds a divergence and it also trace automatically some lines on the chart and the MACD where the divergences are, very nice, I would like to that everytime it pop a sound alert it also send me mail to my gmail something like "ERUSUD 4h bullish div alert". Im sure i need to modify the indicator in the medaeditor and add a few lines but i dont have any idea of how to do it. Please help me out.
