Trade history returns by Period

As it currently stands, we can view the return history usually offered in traditional charts => 1D 1W 1M, etc...

However, these views are somewhat misguiding because an influx of new investments will translate into a sharp increase in BTC (shown in the chart) value that is completely unrelated to the performance of the trader. 

As an additional view, I would suggest adding charts by trading periods. That should give the investor a better understanding of the returns and an easy way for the team to chart returns:
- Last trading period return => 2.7%      <- previous    next ->

- Last 5 trading periods => 1.3%      <- previous 5      next 5 ->

etc...
