This was updated from script of ChrisMoody published on 4-10-2014.
This MACD is an overlayed version instead of separated indicator.
I re-color lines and histogram for my own trading strategy.
For example, look the screenshot, you can see that even though price from 1 to 2 is ascending, but on histogram, the volume from 1 to 2 is descending, which means there will be a reversal of price.
So we wait until the second red volume appears (marked with an arrow on top) we can place a short order. Or, to make sure, we can wait until the red dot (marked with "X" letter) appears to do that.
Same with buy order.
This is just a suggestion for trading strategy, not a guarantee, everything can happen, you should spend time to inspect the indicator to make sure you understand it before use for trading.
And YOU TRADE WITH YOUR OWN RISKS!
Hope you like it.
