David Fuller's view Price charts alert us to changes of potential significance.

Brent crude oil (weekly & daily) encountered resistance from its 2-year range highs in February and is now testing lower boundaries commencing near the psychological $100 level. A close above $107 is now required to reaffirm more than temporary support near today's lows.

Platinum fell sharply in February after testing resistance from two earlier peaks just beneath $1750, dating back to February and October 2012. It is now testing the two previous range lows just beneath $1400. Since investors will know that similar range lows in gold and silver were decisively broken on Friday and followed by even bigger slumps today, platinum is unlikely to encounter more than temporary support near current levels before moving somewhat lower.

Palladium had been a relative strength standout in precious metals earlier this year but has encountered resistance from its earlier peaks. As of today it has also failed to maintain breaks above last year's highs and also its 200-day MA. A test of the range lows appears likely.

Silver (weekly & daily) was the only precious metal to see a dramatically accelerated peak, from which it has now fallen by over 50%. It is also approaching the first area of potentially significant support, commencing near $20. My recollection is that silver generally follows rather than initiates recoveries but that once underway, it performs like a high-beta version of gold.

The USA's downward dynamics for the S&P 500 (weekly & daily) and NDX (weekly & daily) suggest that we have seen rally highs of at least near-term significance. Closes above last week's highs are required to question the current outlook for a further retracement of this year's gains.

Japan's somewhat firmer yen indicates that the Nikkei (weekly & daily) is susceptible to some further reaction and consolidation before the uptrend is extended but a close beneath 11,800 would be require to indicate more than a short-term peak.
