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'm having the same problem with the scan set up for just a simple "fplot" crossing the "negrms" on the weekly. To complicated algo?

Plot crosses posrms/negrms doesn't yield any results on TOS scanner. Any help?

scan would be difficult with ALMA moving average but with Hull Mov Avg can work. It wont be same but close.

try this . Change the CrossUp and CrossDn.

Thank you Samer800. I just adjusted the CrossUp to the negrams and # out the CrossDn, set the aggregation period to weekly and it works perfectly. Awesome!
 
This looks really nice is there a way to keep top of chart separate from lower
what I am trying to say is not have the candles turning grey.
Thank you
 
Great indicator. Is there a way to change the cloud colors and indicator line colors to red at the overbought area and to green at the oversold area?
Thank you for sharing.
 
This works great for catching the C leg of the A + C symmetry on the higher time frames, using the 5 min, could you add the MTF preference for testing?

I added some oversold/overbought levels. Also changed some inputs. http://tos.mx/TjQKgMI

@samer800 Could you please add MTF to this script, I tried a few times to do it myself and couldn't could you kindly add this thanks
 
I tried to convert this to MTF, Not able to get it right. Please advise.

Can someone add a buy and sell signals when the FPLOT line turns from white to red and from white to green.
If color changes to green when below zero line = Reg Buy
If color changes to green when above zero line = Extreme Buy
If color changes to red when below zero line = Extreme Buy
If color changes to red when above zero line = Reg Buy
