Hi Ilya,

If your focus is on intraday price shocks - you could check out our
PortfolioEffectHFT package.

Right now it's available at:
It would also be available on CRAN shortly under BSD license - we are doing

For intraday volatility estimators see portfolio_variance
& position_

PortfolioEffect service is free to use with your own pricing data.
There is optional access to HF market data history for 8000+ US equities
since 2013 if you need that.
