[R-SIG-Finance] What happens to IBrokers package if overloaded ?

[amarjit chandhial]

Are there any simple examples in R for viewing real-time scrolling charts, updating real-time technical indicators, generating real-time alerts when MA's crossover/oscillators reach thresholds, etc ?

Reading 100 symbols every 5 secs with reqRealTimeBars() does not cause
performance problems.  What *may* cause performance trouble is the
processing you do AFTER receiving the data, e.g. calculate indicators,
refit-models,etc. But that entirely depends on how computationally
expensive   your decision-making process (=strategy) is.  If it takes
longer than 5 secs then you have a problem.
