Traduction code ifvg de Luxalgo

Bonjour, tout d’abord je vous souhaite une bonne année 2025. j’ai découvert un indicateur génial qui est l’ifvg (inversion fair value gap) codé par LuxAlgo et qui pourrait intéresser beaucoup de monde je pense. Lorsqu’une fvg baissière est breakée, cette dernière devient alors une zone de support (et inversement avec une FVG haussière). Malheureusement, je ne sais pas coder sur PRT et je me demande si une âme charitable pourrait proposer une conversion de ce super indicateur de Tradingview pour PRT. Un grand merci d’avance pour votre aide. Cordialement. // This work is licensed under a Attribution-NonCommercial-ShareAlike 4.0 International (CC BY-NC-SA 4.0) https://creativecommons.org/licenses/by-nc-sa/4.0/ // ©LuxAlgo //@version=5 indicator("Inversion Fair Value Gaps (IFVG) [LuxAlgo]", "LuxAlgo - Inversion Fair Value Gaps (IFVG)", overlay = true, max_boxes_count = 500, max_lines_count = 500, max_labels_count = 500) //---------------------------------------------------------------------------------------------------------------------} //Settings //---------------------------------------------------------------------------------------------------------------------{ disp_num = input.int(5, maxval = 100, minval = 1, title = "Show Last", tooltip = "Specifies the amount of most recent inversion FVG to display in Bullish/Bearish pairs, starting at the current and looking back.") signal_pref = input.string("Close", title = "Signal Preference", options = ["Close","Wick"], tooltip = "Choose to send signals based on Wicks or Close Price.") wt = signal_pref == "Wick" atr_multi = input.float(0.25, step = 0.25,minval = 0, title = "ATR Multiplier", tooltip = "Filters FVGs based on ATR Width, Only displays Inversions that are Greater-Than the ATR*Multiplier.") //Colors green = input.color(color.new(#089981, 80), title = "Bull Color", group = "Colors") red = input.color(color.new(#f23645, 80), title = "Bear Color", group = "Colors") gray = input.color(#787b86, title = "Midline Color", group = "Colors") invis = color.rgb(0,0,0,100) //---------------------------------------------------------------------------------------------------------------------} //UDT's //---------------------------------------------------------------------------------------------------------------------{ type lab //Contains Necessary Label Data to Send to Label Function int x float y int dir type fvg //Contains Necessary FVG Data to Send to Chart. int left = na float top = na int right = na float bot = na float mid = na int dir = na int state = na array<lab> labs = na int x_val = na //---------------------------------------------------------------------------------------------------------------------} //Functions //---------------------------------------------------------------------------------------------------------------------{ //Basic Calcs buffer = 100 //How many FVGs to keep in memory. c_top = math.max(open,close) c_bot = math.min(open,close) label_maker(_x,_y,_dir) => //Used for making Labels switch _dir == 1 => label.new(_x,_y,"\n▲", style = label.style_text_outline, color = invis, textcolor = color.new(green,0), size = size.small, xloc = xloc.bar_time) _dir == -1 => label.new(_x,_y, "▼\n", style = label.style_text_outline, color = invis, textcolor = color.new(red,0), size = size.small, xloc = xloc.bar_time) fvg_manage(_ary,_inv_ary) => //First step filtering of FVG data, Not all FVGs will be displayed, only inversions. if _ary.size() >= buffer _ary.shift() if _ary.size() > 0 for i = _ary.size()-1 to 0 value = _ary.get(i) _dir = value.dir if _dir == 1 and (c_bot < value.bot) value.x_val := time _inv_ary.push(_ary.remove(i)) if _dir == -1 and (c_top > value.top) value.x_val := time _inv_ary.push(_ary.remove(i)) inv_manage(_ary) => //All inversions will be displayed. fire = false if _ary.size() >= buffer _ary.shift() if _ary.size() > 0 for i = _ary.size()-1 to 0 value = _ary.get(i) bx_top = value.top bx_bot = value.bot _dir = value.dir st = value.state if (st == 0 and _dir == 1) value.state := 1 value.dir := -1 if (_dir == -1 and st == 0) value.state := 1 value.dir := 1 if st >= 1 value.right := time if (_dir == -1 and st == 1 and close < bx_bot and (wt?high:close[1]) >= bx_bot and (wt?high:close[1]) < bx_top) value.labs.push(lab.new(time,bx_top,-1)) fire := true if (_dir == 1 and st == 1 and close > bx_top and (wt?low:close[1]) <= bx_top and (wt?low:close[1]) > bx_bot) value.labs.push(lab.new(time,bx_bot,1)) fire := true if st >= 1 and ((_dir == -1 and c_top > bx_top) or (_dir == 1 and c_bot < bx_bot)) _ary.remove(i) fire send_it(_ary) => // Draws Everything on the Chart last_index = _ary.size()-1 for [index,value] in _ary bx_top = value.top bx_bot = value.bot bx_left = value.left xval = value.x_val mid = value.mid col = value.dir == -1 ?

Exact. C'est à cause de ce que dit Razz. Pour éviter cela, il suffirait de limiter les itérations de boucle. par exemple : for i=n downto max(n-100,0) do
