Who's your broker and what platform are you using? Most platforms offer this for free. For instance, SierraChart, CQG, and Thinkorswim all provide T&S in their platform. Only platform I know that doesn't have it is TradingView, which is more catered to beginner than advanced traders (no offense). But it does provide a nice looking chart though.
Historical T&S data: https://www.tickdata.com/ (high quality) or http://anfutures.com/ (possibly lower quality) Historical (~10 years) of 1-minute bars and real time T&S: https://www.iqfeed.net/
Have used the data of both in the recent past ... In my opinion, it should be said this way - Historical T&S data: https://www.tickdata.com/ (highest price) or https://www.anfutures.com/ (lowest price)... with almost equal quality, since they have the same source of data - CME.
databento.com $388.38 (after credit) for 2 years, tick-by-tick, and includes every expiration — not just 1-2 lead month contracts — and spread contract each day. Cheaper if you use our API and discard the spreads or expirations that you don't want. We're also the only source I know that provides nanosecond resolution PTP timestamping for the historical data.
