How to get top losers using set_universe function

I have found this set_universe function to find the top gainers

set_universe(universe.DollarVolumeUniverse(  
            floor_percentile=99.0, ceiling_percentile=100.0))  

is there a function to find daily top losers also?

Click here and search for the Mean Reversion Example

That will show you how to set the upper and lower percentiles of the universe you are attempting to trade for.
