We empirically study the market impact of trading orders. We are speci cally interested in large trading orders that are executed incrementally, which we call hidden orders. These are reconstructed ba...
We propose and discuss some toy models of stock markets using the same operatorial approach adopted in quantum mechanics. Our models are suggested by the discrete nature of the number of shares and of...
