Quote from Grob109:
Volume indicators fall into three categories:
MA's, OSC, and ROC's
A hybrid class also exists where price and volume are combined.
Some of the Accumulation/Distributuion indicators fal into this hybrid class.
The general use of volume for making money relates to its use as a leading indicator of price.
One thing you can do is get some reference books on the use of indicators. A basic one is: Technical analysis from A to Z. the author, Steven B. Achelis is CEO of equis who makes Metastcok software.
The foundaion of TA is the P, V relationship which confirms how all patterns work. You can use this relationship as the basic guide for all money making. Charting with price and volume is like clockwork once you decide the money velocity of profit taking that works best for you. I work on the 30 min equities charts and the 5 min index charts.
I go to slower charts for the slower trends. Today, Monday is such; I am on the 15 min chart and the profits are running at about 2 points per hour since the open.
Correspendingly, this week the equities are running 3 to 5 % a day.
Volume is the key trading timing signal generator.
