what wrong in the code? n = 4 h = highest[n] l = lowest[n] once b = 2 v = h if h = high[n-1] and high[n-1] > high and high[n-1] > low and (b = 1 or b = 2 ) then v = h b = 0 else if l = low[n-1] and low[n-1] < low and low[n-1] < high and ( b = 0 or b = 2 ) then v = l b = 1 else v = v[1] endif endif return v
