Live stats report the wrong number of transactions per open position

[lacabra]

Catalyst 0.4.4:

When I hold several positions, and place a new order, the number of transactions gets copied on all positions, instead of only the one that I just bought. Sample output (you need to scroll right...)

In the example above, instead of reporting one new transaction for cnd_btc, it reports one new transaction for every position I have open.

Good catch. We need to either include "transaction" in the index of the DataFrame of make if specific to each position. Currently, the number of transactions is global to the frame and apparently not in the index.

Grouped into the header for now. We could break these down by positions if we wanted to.
