SPDR S&P 500 (SPY)

[USDollar]

It's foolish to look at a calendaristic anniversary alone without a technical anniversary match (similarity in chart setup)

Furthermore, once you already have a position in the market it's foolish to look around for low-sense information like "anniversary" to evaluate your situation as you will be biased and tend to only see things supporting your bias, which will alter your senses and will hinder your ability to see if you are positioned wrong and you will be potentially dancing on the Titanic all the way to the end.

Best is to have a clear cut criteria for your trade. Then if THAT changes , then you exit your money.

Well, ... unless you like gambling, in which case sanity of trading doesn't matter, so forget about my take...
