I have found Tradestation provides the longest intraday historic data available from the retail data offerings at a reasonable cost.
Maintain a minimum acct balance, ask for their best data package/deal ~ $125/month for platform & Data:
[Equities CME, CBOT, COMEX, NYMEX]
Platform fee waived for minimum activity

I would stick with your IB/MC combination for entry charts, and use TS mainly for research.
