cd, this is how I see Dax. I agree in hindsight its fine but it might give you something to look at.
Initially on the daily chart below, we broke violently lower and have since retraced approx 50% and run out of steam with a number of similar length bars. I would be looking for the next move down and would be wary of a break to new (week - 2 week) lows.
On the 2 min chart I have tried to show how I see things. The rectangle is difficult to trade, I think you either sell new highs or buy new lows but its not easy. I have then included horizontal lines which I think are areas where I would either be selling the bounce (so sit on offer) or more likely hitting bids as we break lower. Today is an extreme day as there is a big violent move without much retracement (ie trendline). When this breaks I would look to see if its likely to go lower or not and sell each break of my red line.
Hope this helps and feel free to ask questions.
