Quantified StockTwits messages are flashing a sell signal for gold (GLD). After advancing for three months with support from the StockTwits stream GLD has turned over at a long term trend line for price. The reversal in price was preceded by a negative divergence from StockTwits that lasted a month. Now support from the StockTwits community has broke the confirming up trend in support. This creates the sell signal and increases the odds that GLD will at least consolidate in the near term and possibly resume its long term down trend.
