Charting 2.0, page-1114

And I suggested that TA has LESS meaning because when you chart with low-volume stocks, you're not really getting the full picture and are simply implying that any price movement, up or down, is due to the workings of Mr.Market (a wider perspective), when in fact it's more than likely that sudden changes are due to a select FEW who have decided to sell or buy a large amount. Therefore the actual data you are using to chart with is LESS robust than if the same practice was used to analyse LARGE volume stocks where there are more players making trades.
