Hi Fureien,
Check out http://stockcharts.com/school/doku.php?id=chart_school:technical_indicators for a list of indicators and how to use them. It has a list of the indicators including the ones I've mentioned. For me to explain it properly its hardly going to be a small post. Macd and rsi are probably 2 of the most popular indicators so I would recommend reading up about them.
As for POO it stands for Price Of Oil.
Hope this helps.
Cheers,
thanks very helpful mate! yeh i use macd and other stuff, but i never actually understood them or what the lines mean when they cross etc. great link
Price of Oil OHHHH!!! lol everything makes sense now
