Как создать индикаторы TradingView, которые выглядят так?

Я пытался создать аналогичный индикатор этому

У меня есть код для RSI, Stochastic RSI, MACD и 50/100/200 MA (с крестами), но я не мог найти информацию о том, как создать визуализацию, как в справочнике, хотя я довольно долго изучал

Вот код этих индикаторов:

50/100/200 МА с крестами (кодировал сам)

indicator(title = "3 EMA with Cross", shorttitle = "3EMA Cross", overlay=true)
fast = 50
mid = 100
slow = 200
fastEMA = ta.ema(close, fast)
midEMA = ta.ema(close, mid)
slowEMA = ta.ema(close, slow)

bullishCross = ta.crossover(fastEMA, slowEMA)
bearishCross = ta.crossunder(fastEMA, slowEMA)

if (bullishCross)
    lbl = label.new(bar_index, low, "Golden Cross")
    label.set_color(lbl, color.green)
    label.set_yloc(lbl, yloc.belowbar)
    label.set_style(lbl, label.style_label_up)

if (bearishCross)
    lbl = label.new(bar_index, low, "Death Cross")
    label.set_color(lbl, color.red)
    label.set_yloc(lbl, yloc.abovebar)
    label.set_style(lbl, label.style_label_down)
plot(fastEMA, color=color.green, linewidth=2)
plot(midEMA, color=color.yellow, linewidth=2)
plot(slowEMA, color=color.red, linewidth=2)
