Hello everyone, sorry if this post breaks any rules, I'm very new here. 

I've been learning QuantConnect for a few months now, and there is one feature I really wish was available within the documentation, specifically - example returns values for the indicators. I believe this would make QuantConnect much easier to understand for beginners, plus it would lead to visiting the LEAN repo just a little less often.

For example, some of the indicators have it already (such as RSI):
 

Creates a new RelativeStrengthIndex indicator. This will produce an oscillator that ranges from 0 to 100 based on the ratio of average gains to average losses over the specified period.

Returns:
  The RelativeStrengthIndex indicator for the requested symbol over the specified period

In this case, the documentation makes it clear that you should expect a value from 0 to 100.

However, there are some that do not have details on the range of values (such as the Rate of Change Ratio indicator):
 

Creates a new RateOfChangeRatio indicator.

Returns:
  The RateOfChangeRatio indicator for the requested symbol over the specified period

It would be helpful to have information about what values to expect (zero to infinity, in this case). Same with, for example, Sortino Ratio: 
 

The symbol whose Sortino we want
Creates a new Sortino indicator.

While, to experienced traders, the range of a Sortino ratio is common knowledge, it would be beneficial to have that information available on-hover right within QuantConnect as quick reference material.

Thank you again for making a great product!
