Type of cross being submitted to a market
1 = Cross AON - cross tade which is executed complete or not. Both sides are treated in the same manner. This is equivalent to an "All or None".
2 = Cross IOC - cross trade which is executed partially and the rest is cancelled. One side is fully executed, the other side is partially executed with the remainder being cancelled. This is equivalent to an IOC on the other side. Note: CrossPrioritization <550> field may be used to indicate which side should fully execute in this scenario.
3 = Cross One Side - cross trade which is partially executed with the unfilled portions remaining active.. One side of the corss is fully executed (as denoted by the CrossPrioritization <550> field), but the unfilled portion remains active.
4 = Cross Same Price - cross trade is executed with existing orders with the same price. In this case other orders exist with the same price, the quantity of the Cross is executed against the existing orders and quotes, the remainder of the corss is executed against the other side of the cross. The two sides potentially have different quantities.
