Answer 1

Using Linq to NHibernate:

var X = 0; // or whatever the identifier type.
var result = Session.Linq()
                 .Where(trade => trade.AccountFrom.Company.ID == X ||
                                 trade.AccountTo.Company.ID == X)
                 .ToList();

Using HQL:

var X = 0; // or whatever the identifier type.
var hql = "from Trade trade where trade.AccountFrom.Company.ID = :companyId or trade.AccountTo.Company.ID = :companyID";
var result = Session.CreateQuery(hql)
                 .SetParameter("companyId", X)
                 .List();
