Abstract
Through slow changes in the position of the traders, we introduce correlations between the volatility (root mean square change) of the prices at different times. We find this volatility correlation to decay slowly with time, as also observed in reality, and quite independent of the dimensionality of the lattice. We also make the trading activity of a cluster of traders proportional to the cluster size.
