Where to find "classical" MACD indicator mql4 code?

What I mean by traditional MACD is this one
Moving Average Convergence-Divergence (MACD) - ChartSchool - StockCharts.com

The one on Metatrader is missing something. The one I found here
MACD Revisited - MQL4 forum
is not exactly what I’m looking for, I look for exactly the same as stockchart (or oanda).

Any mql4 code available ?
Thanks.
