NEW YORK (

) -- The dollar index continues to hold in short mode, with weak trend and sentiment readings that seem to make another test of 77.00 support inevitable.

The dollar was unable to make gains against major rivals when global stocks moved into their four-day slide last week, revealing that the global banking system is as yet unwilling to commit to either side of the dollar in strong numbers. That may be the norm as long as there are global civil unrest and uncertain outlooks regarding central banks' quantitative easing programs.

The 20-day simple moving average at 78.00 is now upside resistance that will be very difficult to break. That said, tests of support have been initially bought on an intraday basis, with moves lower on the dollar index being heavily reversed in the subsequent trading period.

The Swiss franc and Japanese yen have dominated the dollar over the last five trading sessions, and if their weighting within the dollar index was more than the current 15%, traders would have seen a collapse in dollar index futures valuations.

The euro, the pound and the Canadian and Australian dollars have all managed to find buyers against the greenback, albeit in somewhat erratic trading periods.

Next week will see red-flag economic releases, so now would not be the time to commit too much to either side of any individual currency pair. Signals will be forthcoming as the trading week gets started, with tests of trend, momentum and price action likely to be seen as the week unfolds.
