Solicito si es posible, ayuda para intentar convertir el indicador adjunto.

Dicho indicador procede de Tradingview , utilizando arrays. Esencialmente, solo combina 2 EMA ( 9 y 21, totalmente configurables lógicamente) con un análisis basado en ATR para calcular el rango promedio que experimenta el precio después de un cruce de EMA 9 / 21 bien al alza o a la baja.

La longitud del ATR está predeterminada en 500, pero una vez más indico que es personalizable.

Adjunto gráfico y código:

indicator(“EMA 9/21 with Target Price [SS]”, overlay=true)

arraylookback = input.float(500, “ATR Lookback Length”)

showlbls = input.bool(true, “Show Target Price Labels”)

ema9=ta.ema(close,9)

ema21=ta.ema(close,21)

// determine the crossover points

ema9_cross_ema21 = ta.crossover(ema9, ema21)

ema21_cross_ema9 = ta.crossover(ema21, ema9)

// plot arrows on the chart at the crossover points

plotshape(ema9_cross_ema21 ? close : na, title=”Up Arrow”, location=location.belowbar, style=shape.triangleup, size=size.small, color=color.green)

plotshape(ema21_cross_ema9 ? close : na, title=”Down Arrow”, location=location.abovebar, style=shape.triangledown, size=size.small, color=color.red)

// sentiment

Buenas tardes, he intentado convertir yo mismo el indicador, pero dado mi desconocimiento de las arrays me indica lo siguiente: “se espera un campo entero positivo para SRC” y creo que es por algo relacionado con las arrays.

Podría alguien ayudarme.

Muchas gracias por anticipado.

Alguien podría decirme u orientarme por favor, si mi intento de programación del indicador que solicité, tiene algo que ver con el.

Realmente me da error y no me representa nada.

Siento ser tan pesado.

Hola
Le echo un vistazo y te digo.
Ten en cuenta que hay bastantes solicitudes de traducción de tradingview a Prt.
