comment How credible is Knight pointing the finger at Rule 107C?
Don't believe everything you read on Bloomberg; the data is not consistent with that story: nanex.net/aqck2/4008.html

comment Trade Count Time Series
You asked if the data was "available somewhere for download or purchase." You don't have to make any trades in order to get the data although you may have to pay something like 10 or 20 dollars a month. You may even be able to get the data with a paper trading account for free.

comment Backtest pair trade strategy in R
(1) Your example is not reproducible. (2) You should NOT use all the data to calculate your hedge ratio (3) With intra-day data, you probably need to account for bid-ask spread (4) Do you really want returns? Most intraday traders use enough leverage that they care more about PnL than returns. (5) Once you have a signal for the spread, you can easily apply it to each leg separately. (6) Last I looked at the PairTrading package, I thought they got some things backwards. Maybe they just look at things differently than me, but I could not figure out how to get their results to match my own.

comment Free intra-day equity data source
@DarrenCook. You couldn't get TRADES data for a week ago because IB does not provide that for FX. Try using whatToShow="BID", or whatToShow="ASK". Or, use the twsInstrument package (on R-Forge) to get 1 minute Bid, Ask, Mid snapshots (look at twsInstrument:::reqTBBOhistory)

comment Do you have historical tick data you want to donate?
From Dukascopy's website: "Please note: CSV data automatic download (robots, agents, etc) is not allowed. Your IP address will be blocked automatically at once and forever in case of failure to comply with these requirements." Alos, "It is prohibited to publicly display any part of the Data or disseminate it to any third parties."

comment Free intra-day equity data source
@DarrenCook Flat-out wrong. They keep 1 year of historical data for equities. If you want hourly data, then you can only request 1 month at a time, but you can make 60 requests every 10 minutes. If you use R, look at IBrokers:::reqHistory for a wrapper to download 365 days of minutely data. (IB even offers 1 second bars if you're patient enough to respect the 60 requests every 10 minutes pacing rule)

A calendar spread option is not the same thing as a calendar spread of options. cmegroup.com/trading/interest-rates/stir/…
