Query regarding historical depth for total 1-min candle Buy and Sell Volume

Hello TrueData Team & Community,

I am looking to understand the historical data availability for specific candle-level volume metrics.

Could you please confirm how far back (in years/months) your historical data goes for 1-minute candles that include the total Buy Volume and total Sell Volume?

To clarify, I do not need the breakdown for each individual price level/tick. I just need the total aggregated Buy Volume and total aggregated Sell Volume for the entire 1-minute bar.
