I noticed my backtest was reporting fees a lot lower than I expected. It only trades options and use IB brokerage model. I debugged a local lean instance using test AAPL data and could verify that indeed it was constantly choosing the tier with premium < 0.05 because the value of order.Price passed to the fee function is always 0 for limit orders (may be true for other order types as well)

Jared Broad - I added some more comments because I am not sure there is an easy quick solution to it. Also as the original reporter stated, the test case for this is broken, it asserts the wrong value which makes the test pass
