Data notes
- Signal performance is a live-only track record: real published signals with SHA-256 receipts, evaluated net of fees, slippage and funding. Never backtests. Verify any signal at bykaranteli.com/verify.
- Funding, OI and pressure data refresh every 15 to 30 minutes; indices every 30 minutes.
- Nothing here is financial advice. See bykaranteli.com/risk-guide.
