The CF Backend Maintains a db of the positions for each portfolio
(relatively static data -- only changes when stocks are bought, sold
split, etc)
The CF Backend maintains session data essentially the data in the
client machine's grid.
When streaming data is received it is compared against the client's
grid on the host any value color changes (only) are sent to the client
machine (the next time the client machine requests changes)
Its a little more complex than that, because you need to handle
multiple positions on the same stock,
And the color of the cells containing static data (e.g. buy/sell
thresholds) could change as the price nears these thresholds.
but, yes the initial grid is populated with static data from the db and
dynamic data from the streamer.
From then on, only changes (colors and data) are sent to the client
machine as fast as requested -- no changes, no data.
