Request for Official E-mini S&P 500 ES and Nasdaq 100 NQ Futures Data

I am learning Al Brooks' price action trading methodology and need to analyze the market candle by candle in detail. However, Al Brooks exclusively uses the ES E-mini S&P 500 futures charts. There is a huge discrepancy between regular S&P index data and actual futures data. Every time I finish my practice and review, I compare my analysis with the chart reviews on Al Brooks’ official website, and there are always major differences in price structure and market behavior, which makes it impossible to follow and learn consistently.
