Those are probably stock tickers that you look at on TOS. I don’t believe those indices are as standardized. Tradingview has similar data mapped on charts, just type in “put call ratio” in search there and you’ll see a variety of charts that include P/C ratio for major indices, P/C ratio stocks and P/C ratio aggregate. Stockcharts as you already discovered is another source

I usually have multiple “boards” with different levels (trendlines, support/resistance, chart patterns, Fib levels, etc.) on the same security on the same time frame. Here’s another one of my weekly charts of SPY showing the large Broadening Wedge/Megaphone pattern.

Agreed. That’s the primary bull market uptrend line on my weekly chart, which I don’t believe I covered in this video but usually do when going over the longer-term charts. Here’s that weekly chart of SPY with that primary bull market uptrend line in blue. As you said, the broad market broke down below it in Q4 2018, backtested it from below & then plunged into the Dec 24, 2018 lows, recently backtesting the trendline from below back at the Feb ’20 bull market top with that backtest also followed by a very impulsive rejection (the 36% plunge into the March low). SPY is still very much below that trendline and has remained below since the breakdown in 2018.
