market depth, page-2

News, unless you are using software that can plot and give meaningful analysis to the market depth, I would probably just ignore it. Getting meaningful info from the market depth at a speed that is useful requires a fairly powerful computer (usually co located at the exchange) and a very fast connection. The SPI's lack of liquidity compared to other exchanges makes it prone to sudden moves due to the occasional big order/s and if you are trading it, it is a factor you just have to live with.
