The Global Futures Bottom Indicator is derived from weekly calls and puts. It does not appear very often but it is extremely reliable when the market is at a turning point. It prevents long-term investors from buying at the wrong time and works especially well for option traders because of its incredibly perfect timing.
Unfortunately this indicator does not tell you when to sell. Set yourself a limit if you trade options, or use trailing stop-loss orders if you are a long-term investor. Any zero or minus reading indicates a bottom. Since this indicator was invented and developed it only failed twice on a minus reading if compared to the Dow Jones. This was due to panic selling on August 3rd and August 24th 1990 when Saddam invaded Kuwait.
Readings between 1 and 5 are also very reliable and indicate intermediate bottoms in bull markets
Readings up to 25 may work but should be counterchecked with other indicators such as the Global Futures Market Timing Indicator
Readings above 600 are good breadth indicators and show you that a powerful market move on the upside is to be expected
