Hi everyone,

I am still pretty new to this. I tried searching the forums and wasn't able to find anything similar to this script from TradingView. I am trying to mimic an ATR Trail Stop Strategy script that was created by Ceyhun. Any help is greatly appreciated. Here is the link to his script. https://www.tradingview.com/script/cj3MJWNz/

here is my attempt at converting that TV pinescript code to TOS.
you can turn the fast and slow lines on and off. both need to be on for the cloud shading to be drawn, between them.

lookback = 66
i used GetMaxValueOffset() that uses a lookback number, that is how many bars it looks back to find a signal. i guessed and came up with 66. it may need to be adjusted, i'm not sure. this seems to work, so i didn't create a fold loop.

i added strategy code lines (addorder) at the end, but left them commented out.
this could be loaded as a strategy, change the name, then enable the code lines and set either or both inputs to yes.(enable longs , enable shorts)

i've never made a pine script, so this might be off a little? i just looked up a couple of functions here.
https://www.tradingview.com/pine-script-reference/
i left the original code in and commented it out, so others could verify it and learn from it.
