Its one day down Farsight, how does it mean the rallys over? Markets are a little overbought sure, but how oversold were the markets last year yet they kept getting nailed day after day.... im still mildly bullish, but thats only because of the trend, we are due a 'pause that refreshes', but if any attempts higher over the next few days fail then i'll be the first to turn positions around to the dark side of the force.....
