Qtpylib

--------

- Requires ezIBpy >= 1.12.31
- Added ``instrument.get_contract_details()`` and ``instrument.tickerId()`` methods (see API reference section in docs for more info)
- ``futures.get_contract_ticksize()`` marked as deprecated (``instrument.get_ticksize()`` or ``instrument.ticksize`` instead)
- Ignoring ``ticksize`` parameter in ``order()`` (ezIBpy's auto detects min. tick size based on contract spec.)

--------

- Interval-based bars are now tread-safe and working correctly when ``"force_resolution" = True``


*November 11, 2016*

--------

- Fixed a bug that prevented backtesting second-level resolution strategies

--------

- Introduced ``force_resolution`` parameter in ``Algo`` to force a new bar on every ``resolution`` even if no new ticks received (default is False)

--------

- Fixed parsing of flag params (related to issue 17)


*November 10, 2016*

--------

- Fixed bar events in backtesting mode to fire every 250ms instead of 2.5s (closing issue 21)
- Fixed parsing of ``backtest`` param in ``Algo`` (closes issue 17)
