For example, a market can appear fairly stable at 5.0 (back price) and 5.1 (lay price), then all of a sudden without warning (i.e. no previous volatility in price movement) the back price will drop to 4.5 or 4.6 followed by a spike on the money matched graph.
Has anybody else noticed this? If so are you able to see any trend in how the market responds after the flood of money? What strategy are you using to manage your positions?
