The VIX Fix measures how close the current market price is to the lowest price of the last X candles. When prices are in uptrends, the close is usually near the high. But prices close near the low in downtrends. It works because it’s based on how traders behave. The calculation fixes some of the problems with the VIX.
This indicator is based on CM_Williams_Vix_Fix Finds Market Bottoms and its great difference is that it adds the inverse functionality, also showing the possible highest areas of the market.
