  Can someone please help me convert Trendilio Indicator to PRT? Here is the code

  Trendilio Code from Tradingview

  //@version=5 indicator('Trendilo', overlay=false) src = input(close, title='Source') smooth = input.int(1, title='Smoothing', minval=1) length = input.int(50, title='Lookback', minval=1) offset = input.float(0.85, title='ALMA Offset', step=0.01) sigma = input.int(6, title='ALMA Sigma', minval=0) bmult = input(1.0, 'Band Multiplier') cblen = input(false, 'Custom Band Length ? (Else same as Lookback)') blen = input(20, 'Custom Band Length') highlight = input(true) fill = input(true) barcol = input(false, 'Bar Color') pch = ta.change(src, smooth) / src * 100 avpch = ta.alma(pch, length, offset, sigma) blength = cblen ? blen : length rms = bmult * math.sqrt(math.sum(avpch * avpch, blength) / blength) cdir = avpch > rms ? 1 : avpch < -rms ? -1 : 0 col = cdir == 1 ? color.lime : cdir == -1 ? color.red : color.gray fplot = plot(avpch, color=highlight ? col : color.blue, linewidth=2) posrms = plot(rms, color=color.new(color.purple, 0)) negrms = plot(-rms, color=color.new(color.purple, 0)) fill(fplot, posrms, color=fill and cdir > 0 ? col : na, transp=50) fill(fplot, negrms, color=fill and cdir < 0 ? col : na, transp=50) barcolor(color=barcol ? col : na) hline(0)

  I added the conversion to the list. Thank you for your patience 🙂

  Text Trading View:

  The provided code is a custom indicator called “Trendilo” in TradingView. It helps traders identify trends in price data. The indicator calculates the percentage change of the chosen price source and applies smoothing to it. Then, it calculates the Arnaud Legoux Moving Average (ALMA) of the smoothed percentage change. The ALMA is compared to a root mean square (RMS) band, which represents the expected range of the ALMA values. Based on this comparison, the indicator determines whether the trend is up, down, or sideways. The indicator line is plotted in a color corresponding to the trend direction. The indicator also provides the option to fill the area between the indicator line and the RMS band. Additionally, users can choose to color the bars of the chart based on the trend direction. Overall, the “Trendilo” indicator helps traders visually identify trends and potential reversals in the price data.

  I don’t know if I’m wrong. But now this complex calculation does not necessarily have better results than a simple MACD indicator.

  Thanks a lot phoentzs and Nicolas.

  You are right, just using ALMA gives better entries than this indicator.

  It is a request from @Boonet, to use without obligation or not…

  That wasn’t a criticism, just a statement. 😉 Often it is better to fall back on simple things.

  My experience is that there is nothing simple about working with digital signals… 🙂

  Thank you @JS, it helps me a lot if you do conversion from time to time 🙂

  @JS Me too. Otherwise we would all be rich by now. 😉 In my experience, standard indicators, used correctly, are no worse than complex programming.
