Query: Uncertainty relations in models of market microstructure   This paper presents a new interacting particle system and uses it as a spin
model for financial market microstructure. The asymptotic analysis of this
stochastic process exhibits a lower bound to the contemporaneous measurement of
price and trading volume under the invariant measure in the `frozen' phase of
the supercritical regime.
