NDX: SEE CHART GET CHAIN FIND STRATEGIES
The Nasdaq has halted trading because of technical problems in a highly unusual move but now says that it will reopen "at a time to be determined."

The week began with highly publicized bad trades from Goldman Sachs on Monday, followed by some unusual action involing the CBOE Volatility Index and VIX futures settlement for August contracts yesterday morning.

Regardless of what is causing all these problems, the situation will clearly do little instill the already-shaken public confidence in the markets.
