SP500 Open Interest

Interesting alarm was activated today. It is when open interest drops more than ~15% is what i think I have it set to.

In the past this has meant a moderate to severe drop in the SP500 or a major trend reversal as seen last XMAS.

I think what it means is make sure you have a well defined stop loss or skim some winners off the top until we build a base up here and it seems sturdy.
