You will understand my reluctance to contribute anything further to this discussion, until I can fully comprehend the very complex concept of "trends in the market," as alluded to previously by Grand Master Miles.
In order to tackle this momentous task I am deploying a multifaceted approach: reading the finance section of The Daily Telegraph and perusing that wonderful source of credible knowledge-wikipedia.
So I am confident that in time, I will also understand very intricate terms and concepts including "median price," "moving average," "ripple affect" and "sales volume."
