Hi cryptog.
The trades table is actual trades carried out by NuBot. It is currently only trades on Bittrex and some work need to go into the wrappers for the other exchange APIs (mainly southxchange).
USD NAV should definitely include the funds held in other crypto currencies such as ETH. There is a bit of work there to fetch the USD values of those crypto currencies from CoinMarketCap.
I have started on a lot of these tasks but am feeding he data into a separate service that handles the graphing of time series data very well. Over the coming days and weeks I will finish that work and make the improvements that are needed to the current charts as needed.
The Funds link is an attempt at making a graphical representation of fund movements on the Nu blockchain. You can click on addresses there and it will add transactions and additional blocks that funds have moved to from them. I had attempted to use it to trace funds from the breached addresses but it requires some refinement as the number of nodes can become to great and cause the whole thing to crash.
