“…The support and resistance strategy is to buy (sell) when the closing price upward (downward) exceeds the maximum (minimum) closing price over the previous n days (5,10,15,20,25,50,100,150,200,250, giving a total of 10 values). An alternative way is to use the most recent closing price that is greater or less than the e previous closing price as maximum or minimum (2,3,4,5,10,20,25,50,100,200, giving a total of 10 values). Like the moving average, a fixed percentage filter band b (0.001, 0.005, 0.01, 0.015, 0.02, 0.03, 0.04, 0.05, giving a total of 8 values), a time delay filter d days (2, 3, 4 or 5 days, giving a total of 4 values) and a fixed holding time c days (5, 10, 25 or 50 days, giving a total of 4 values) can be included.…”
