I have not changed at all how I trade Dax or Bund, I use a bar that is completely not touching the envelope as trend, I want to stay in a trend longer and have deeper retracements so there are change of trend failures. Two main signals is BB touch with trend and retracement to 10sma providing price is touching envelopes then breakout of lowest high. This is one of the systems where I don't use slope of sma cause the sma is too fast at 10, then have all the others as in chart patterns support/resistance, volume divergences. Am using 11 tick mental stops. Am using time stops.
