History of Good Friday trading:

The Council of Nicaea (A.D. 325) set the date of Easter as the Sunday following the paschal full moon, which is the full moon that falls on or after the vernal equinox (~March 21).  Good Friday is the Friday before Easter. More than you wanted to know, but that's why Easter is a "moveable holiday" like Labor Day or Memorial Day.

The New York Stock Exchange has been closed every Good Friday for over 150 years, with the exception of 1898, 1906, and 1907. The Friday before Easter is the only non-federal holiday observed by the NYSE.

Urban myth says that those times the market was open on Good Friday that the market crashed.  It's a great story but it's not true.  Good Friday in 1907 was actually an up-day, but right in the middle of a 9-month bear market with several panic trading days.

The real reason may be that many Christians went to religious services on Good Friday.  Brokers and exchanges thought that there would be little trading on that day, as well as their employees asking for the afternoon off to attend those services. Passover is the same weekend in 2015.

So the answer is... no one knows, we've always been closed on Good Friday
