These filters select stocks based on how much they have moved in the last minute.  For example you can set the minimum move to $0.50 to see only stocks which have gone up at least 50 cents in the last minute.  Show me.  Or you can set the maximum move to -10% to see only stocks which have gone down by at least 10% over the last minute.  Show me.

Combine these to create a range.  For example, set the maximum to $0.07 and the minimum to $-0.07 to see only stocks which have moved less than 7 cents in either direction in the last minute.  Show me.  This will find stocks which are easier to trade because they are temporarily consolidating.  This can help reduce slippage.

These filters work before, during, and after regular trading hours.
