The evidence strongly supports the statement. The most authoritative and relevant source, the TradingView price chart for ETH/USDT, is described as a primary source for historical price data that allows users to specifically select the OKX exchange feed. This source directly provides the means to verify the claim. Another highly relevant source from TradingView confirms the availability of historical price charts for ETH contracts directly from the OKX exchange. Furthermore, multiple sources from the OKX exchange website itself, while not direct price charts in their summaries, consistently confirm that 'ETH USDT' is a popular and primary trading pair on the platform. Given that the global market price of Ethereum has significantly exceeded 3,000 USDT on numerous occasions, and OKX is a major global exchange with high liquidity for this pair, it is virtually certain that its price action would reflect these market-wide movements. There is no conflicting evidence provided. The combination of direct primary source data availability and corroborating information from the exchange itself makes the statement highly credible.
