How the pieces fit

                     ┌──►  Swaps by Pair    (trade tape, by pool)
trade fills  ────────┼──►  Swaps by Token   (trade tape, by token)
                     └──►  Pair OHLCV        (candles, by pool)

pool post-balances ──►  Pair Reserves       (live depth, by pool)
price updates      ──►  Token Prices        (USD/native marks, by token)

• The swap recipes all draw from the same normalized in-block trade events — direct pool fills (tokenSwaps) and aggregator-routed trades (aggregateTokenSwaps) — so every fill lands exactly once. Key by pool for a pool’s tape, by token for a token’s tape.
• Pair OHLCV is a downstream aggregation of that ingest: the same trades land, then a candle surface buckets them per (pool, hour). “Price” per fill is the bought-leg in-block USD mark; volume is summed notional; trades is the count.
• Pair Reserves reads the pool’s absolute token0PostBalance / token1PostBalance from each swap, so current reserves are simply the latest observation per pair — live depth without reconstructing a running sum.
• Token Prices is the connective tissue for valuation: join any trade, balance, or position to the token’s mark, and use the latest-mark dictionary to value quiet positions with no fresh update.

Notes and considerations

• EVM + Solana. The trade, candle, reserve, and price recipes are chain-parametrized. On Solana, repeated logIndex within one instruction means the pool-fill vendor_event_id should be widened (e.g. with the token addresses/amounts) to keep rows distinct; the candle math is chain-agnostic.
• One trade, two pool addresses. A fill observed both as a direct pool fill (pairAddress) and as part of an aggregator route (aggregatorAddress) appears under both — they are distinct events by design. source_kind (pool_fill vs aggregator) tells them apart.
• USD is in-block only. Trades, candles, and notional are enriched from same-block tokenPriceUpdates — no cross-block carry-forward. Illiquid or brand-new tokens with no in-block mark leave price_usd / notional_usd NULL (and produce candle gaps for that hour). For valuing quiet positions, use the Token Prices latest-mark dictionary, which carries the last on-chain mark forward.
• OHLCV is fixed 1-hour and trade-reconstructed. Candles are built from on-chain swap fills, so they can differ slightly from a DEX’s own reported OHLC. For other intervals, re-bucket the trade ingest. Use candles for the fast accelerator and candles_exact (over fact_swaps FINAL) when post-reorg precision on high/low matters; volume and trades are sign-weighted and always exact.
• Reserves need an in-window swap. Current reserves come from swap post-balances, so a pool appears only if it had at least one swap with resolved post-balances in the ingested window. Quiet pools have unchanged reserves by definition — widen the window to pick them up.
• Run ClickHouse in hybrid for live terminals. It backfills history then hands off to a seamless, reorg-safe realtime tail at the chain head. Postgres/MySQL are first-class for historical backfill; the trade recipes expand many rows per block, so live/reorg-safe ingestion is ClickHouse-only.
• Pair with other bundles. Add Swaps by Wallet for per-user trade history, or see Token Analytics and Portfolio Tracking for adjacent recipe bundles.
