Fear/Greed Index

My goal was to create something akin to the Fear & Greed Index (https://money.cnn.com/data/fear-and-greed/) that CNN and others do.

A Fear/Greed Index can be used by any trader or investor but I believe it's best viewed with a contrarian's eye--

When the market appears to be signalling Extreme Fear, that is a good place to start buying from emotional players who want to sell no matter the price
When signalling Extreme Greed, that may be a good place to start taking profits off or getting hedged, as there may be too much exuberance in the air
Important to note and remember, however, is that there can often times be fear in the air for good reasons! I like to see this as if we dip into extreme fear and return shortly after, the fear may warrant constraint from buying, or returning back to extreme greed may be a very strong market extension

The script draws from several other tickers which I have read and personally observed to be decent macro correlations for the stock market (specifically the SP500). For the state of each of these metrics I gave a rating, good or bad, then added them together and put it into your standard Stochastic.

These macro correlations include--

The % of stocks in the SP500 above multiple Simple Moving Average lengths
VIX and its term-structure (contango, backwardation)
Treasury Bonds
Gold
Junk/High Yield Bonds
The Put/Call Ratio
The SP500 Options Skew
Advancing and Declining Issues

On some of these I opted to use a function for the Relative Momentum Index instead of RSI, as the RMI oscillates better (in my opinion). I also used a Band-Pass Filter/Double EMA for smoothing the results of the stochastic.

A LOT of these numbers were made to my own observation and discretion and can get out-dated over time. With that said, PLEASE feel free to revise, fine tune, modify this as you wish to optimize yours. And please let me know if I have made any mistakes here or something should be added.
