I'm writing my first trivial algo and saw it do something strange. I found what appears to be a data anomaly. These are the end of day close prices returned by both TradeBars and Securities.

2017-04-28 00:00:00 SPXL close price is 32.6600000000000
2017-04-29 00:00:00 SPXL close price is 32.4525000000000
2017-05-02 00:00:00 SPXL close price is 8.1575000000000
2017-05-03 00:00:00 SPXL close price is 32.70000000000
2017-05-04 00:00:00 SPXL close price is 32.54000000000

Is this a data problem or just something I don't understand?  What is the best way to handle this sort of thing?
