I have a interesting question. If the DAX is a index of 30 companies and the DAX chart plots the prices for these 30 companies then why do we get interesting patterns on the DAX like double bottoms, double tops, trendline breakouts etc. I would have thought the DAX charts would not respect technical analysis as prices would just make swings all over the place and not respect technical setups. Many times I have seen price bounce off 00 levels. Do people trade the DAX which then affects the stock price or do people trade stocks which then moves the index?
If the 30 companies in the DAX move the index then can someone please explain why on the chart of a DAX or any index, when we get a double top or a double bottom, why does the price go in the opposite direction. What is actually happening to the prices of the stocks that move the index when we get these setups?
