  user’s indicator Darvas

  hh = highest[n] ll = lowest[n] once state = 2 v = hh if hh = high[n-1] and high[n-1] > high and high[n-1] > low and (state = 1 or state = 2 ) then v = hh state = 0 x = 0 elsif ll = low[n-1] and low[n-1] < low and low[n-1] < high and ( state = 0 or state = 2 ) then x = ll state = 1 v = 0 elsif state = 0 and high > v[1] then v = 0 x = 0 state = 2 elsif state = 1 and low < x[1] then x = 0 v = 0 state = 2 else v = v[1] x = x[1] endif return v AS "Darvas R", x AS "Darvas S"

  1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26

  hh = highest[n] ll = lowest[n] once state = 2 v = hh   if hh = high[n-1] and high[n-1] > high and high[n-1] > low and (state = 1 or state = 2 ) then v = hh state = 0 x = 0 elsif ll = low[n-1] and low[n-1] < low and low[n-1] < high and ( state = 0 or state = 2 ) then x = ll state = 1 v = 0 elsif state = 0 and high > v[1] then v = 0 x = 0 state = 2 elsif state = 1 and low < x[1] then x = 0 v = 0 state = 2 else v = v[1] x = x[1] endif return v AS "Darvas R", x AS "Darvas S"

  Does your variables always return 0? Did you test them with a GRAPH instruction in your strategy already?

  Also, a “defparam preloadbars=100” should help. Because you need historical datas to compute correctly the indicator.
