The Nasdaq tested its system on Tuesday and the New York Stock Exchange (NYX) expects to open its trading floor Wednesday as New York City confronts the damage left by Hurricane Sandy.

That hasn't stopped some in the financial community from adding more moisture to the mix by having a good cry about it.

The NYSE told the Wall Street Journal that it plans to open its floor to normal trading on Wednesday, but will still join Nasdaq (NDAQ), BATS Global Markets and Direct Edge in testing a backup plan. Reuters reported early Tuesday that the firms will see if they can run auctions through the NYSE's Arca platform, but that NYSE and others described the plan as "precautionary," given how relatively well the markets weathered the storm.

"We stress that, as of now, there has been no damage to the NYSE Euronext headquarters that would impair trading floor operations," NYSE said in a statement.

The market closed for weather for the first time since Hurricane Gloria hit New York in 1985. It was also the first multiday closure since the Sept. 11 terrorist attack on the World Trade Center in 2011 and the first multiday weather-related closure since the Blizzard of 1888. While Tuesday's closure is tough for hedge funds and mutual funds that end their fiscal year on Oct. 30, there's a chance they could work around U.S. market closures with help from international markets. There's a bit more motivation to get back to business on Wednesday, if only because traders price their portfolios on the last day of the month.

However, some are still stewing over the NYSE's decision to both close its trading floor and to move all trading to its electronic market. Regulators didn't like that idea because it had only been tested once, back in March, and was complicated by the storm's effect on both infrastructure and staffing.

Fortune expressed its still-raw feelings on the matter on Monday afternoon just as the storm's swells were reaching Lower Manhattan. It argued that electronic trading, which accounts for 90% of all trades, should have continued since the NYSE only handles about 11% of overall U.S. share trading, 40% of stock trades never pass through the exchange and its head of stock trading execution is in Chicago anyway. It added that many other trades are completed elsewhere, but routed through the NYSE system and that what "the last few years have proven is that others can do stock trading just as efficiently as the NYSE."

That's true. While the flash crash of May 2010 that zeroed out several stocks for a few minutes is still the recent standard for terrible technical glitches, Nasdaq's issues with Facebook's (FB) IPO  and Knight Capital's high-profile oops earlier this year showed others can botch stock trades and fry their systems just as efficiently as the NYSE.

Since 2000, trading on the NYSE was either halted or extended three times because of system problems. They caused more days of disruption than the deaths of two presidents during that same span.

"Both regulators and investors are sensitive to odd market moves -- individual investors have a distrust for electronic trading," Oliver Pursche, president of Gary Goldberg Financial Services, told CNNMoney.

Not to mention that the area around the exchange woke up Tuesday morning to Lower Manhattan and Hoboken, N.J., still under water, Breezy Point in Queens decimated by fire, patients from a New York University hospital displaced after power failed, millions still without power and more than 30 people killed by the storm. The markets will open on Wednesday, trades will happen and financial sector life will go on, but for a brief moment the blue-shirted babies will have to stop playing with their portfolios.

During a down period in the European and Chinese markets that could render a U.S. market closure an afterthought, giving the NYSE and others an extra day to dry out falls pretty far down the list of storm-related grievances.
