OrderId remains the same for partially filled orders held overnight - Potentially Breaking

New Tick Sizes when Placing FX Orders
Until now, FX instruments have only had one tick size which was defined by the field 'TickSize' under instrument details.
As of today we will operate with three separate tick sizes when placing orders:
- TickSize: to be used for IOC and FOK orders.
- TickSizeLimitOrder: to be used for Limit orders
- TickSizeStopOrder: to be used for Stop orders.
Until August 15th we will not enforce these new tick sizes when placing orders and instead continue to accept the standard tick size for all orders. After August 15th any order not using the correct tick size for its order type will be rejected.
This will not affect any non-FX instruments.
