SPY- Potential reversal & key levels to watch

The SPY closed on Friday finally breaking below the channel that it's been holding for quite some time now, and closed sitting on the 50-day SMA. Every time we've previously touched the top channel line, the SPY has fallen to the bottom channel line and bounced right off (see charts below). However, there is a very clear shift in seller volume starting to outweigh buyers, and RSI taking a steep drop EOD on Friday after hovering in overbought territory for quite some time as well. Just some FIB levels and RSI-based supply and demand zones to keep an eye on- personally bearish here as the markets have been way overextended for a long time now in my opinion. Trade safe, and look for potential long-term entries on fundamentally sound stocks.
