A sloppy market describes a market with seemingly random trading patterns that lack meaningful trends or behaviours. Often sloppy markets are neither bear nor bull but oscillate between the two. During sloppy markets, traders typically wait for a breakout or a consolidation into a range before entering any trades.
A slippery market may also be used to describe a volatile market, especially when the high volatility increases the risk of slippage when opening and closing trades. Additionally, a slippery market may describe conditions in which the price has consolidated traders feel the market is poised to jump in either direction.
