Price rises to lower highs when RSI rising, hence 'hidden divergence'; RSI looks bullish but price remains bearish, each rally a bulltrap.
Some of these rallies can get pretty fierce, shaking bears loose and sending shorts for cover. Then the trend resumes, trapping bulls.
These bear market whipsaws just kill all the players. When you're in these, you get the feeling; "I just can't win for losing!" ... all traps.
