Strategy based on longing resistance breakout and shorting support breakout. It defines highs and lows using fractal with 2 bars for confirming high/lows. So it has 2 bars lag. It calculates the difference between sma with defined length (21 by default) of highs and of lows and uses it as alt SR level. This idea I took from synapticEx's indicator Nebula-Advanced-Dynamic-Support-Resistance. Position enter is the breakout of SR, defined by fractals. Position exit is: bar change in opposite to position direction > difference is sma of highs and of lows.
thanks in advance
