The problem is how to write the EA code to determine if the market is ranging.
A lot of this method has to deal with the strength of the trend, the MACD histogram, current s/r levels, and past s/r levels. There can be signals that look good on a chart for entry but are in reality 'weak' or conflicting signals. Then there is the case of the 1hr chart to get in earlier with the 4hr trend. The $Yen gave up 95 pips on three trades on the 1hr chart using the 4hr as the direction. The method itself is very simple but one must recognize the rhythm of the market along with the profit targets.
