Enable filtering of managers by trading period and number/frequency of trades

In the list of programs it should be possible to filter managers by trading period - this is helpful, for example, as many investors in the early stages of trying out the platform may want to commit their money for shorter periods of time. 

Some investors may also have a preference for traders making high frequency or algorithmic type of trading, so having a slider filter also for "average number of trades per trading period" or "average number of trades per day" would enable investors to focus down on the type of trader they are looking for.
