Moved your post here since MACD2 is actually bb macd (macd with bollinger bands added to it)
I attach a special Macd indi which shows turning points with a yellow dot very precisely! It wozuld be great to have an alert when the yellow signal flashes to reverse position.
Please have a look at it.
Try now hope these will be work.
Some updated and upgraded versions of bb macd here.
thanks a lot ,
