Exact schema is undocumented but expected to include numerical relationship data useful for constructing time-shifted trading signals.
Example use cases
Crypto pair lead-lag discovery
“Check whether SOL tends to lead or lag BTC in price movements, and by roughly how long on average — I'm building a stat-arb signal around it.”
Equity-futures timing analysis
“I want to know the lead-lag relationship between the S&P 500 ETF and ES futures — which one moves first and what's the typical lag in minutes?”
Cross-asset momentum research
“Pull me the lead-lag data between gold and the dollar index so I can see if one reliably signals the other before a move.”
