Of course, in very strong bull or bear markets, we must rely on technicalindicators that can stay with strongly trending markets, as momentum indicators like the Moving Average Convergence Divergence (MACD) indicator or Relative Strength Index (RSI) will top or bottom out well ahead of prices.
Meanwhile global markets tend to move pretty much in tandem with each other, and an even more ominous divergence has been in place for a while between the resilient U.S. market and numerous important global markets, on which technicalindicators triggered sell signals a month or more ago.
