[R-SIG-Finance] New to R and Finance, backtest etc.

[Jeffrey Ryan]

A few years back (!) I was testing the then current implementation of
IBrokers for throughput.  At the time on a laptop I could see 10k+
messages a second in R max throughput.  Within the context of IB, that
is more than sufficient to handle the incoming data (given symbol
limits and IB's snapshot data approach (300ms or so aggregations on
'mkt data').

This would push a single core to a pretty high cpu utilization, but
easy enough to share data between procs with R.

The 'testing' would really depend on you are doing in terms of trade
logic.  All in all though, aside from real high freq stuff, you can
easily have R running logic and trades - at least if you can temper
the incoming data to something like IB provides.

In terms of 'yes or no' ... I think the best you can get is
'sometimes' (or 'most times' if you aren't looking at the order book
or full market)
