Create Pine Script to combine some indicators / Building a scanner for indicator/chart patterns

Hi, I would like to have two scripts: A pine script that draws some channels around another indicator. I also would like to have dots on certain points where lines are crossing. I can explain more about it in a chat session. Furthermore, if this is a success, I would like to have a divergence scanner, to scan for divergences (EFI, MACD-H ) for the crypto currency coins listed on Tradingview. Ideally with a web interface, so I can fiddle with the settings for the scanner (choose timeframe: 1H, 4H). I also want to have it run and report immediately, or once a day. Do you have shown experience with pine scripting and Tradingview and knowledge about indicators?
