The flow filter chooses the trades a stream subscription delivers, and the market views take a grammar of their own. ## Coverage The table is read live from `GET /v1/meta/filters` and marks each app Traktor tracks on each chain. | Chain | fomo | GMGN | Axiom | Maestro | pump | Padre | Bloom | Trojan | BONKbot | Photon | Coinbase Wallet | Bankr | | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | | Robinhood | yes | yes | yes | yes | | | | | | | | partial | | BNB | yes | yes | yes | yes | | | | | | | | partial | | Base | yes | yes | | yes | | | | | | | partial | partial | | Arc | yes | yes | yes | | | | | | | | | | | Arbitrum | yes | | | | | | | | | | | partial | | Ethereum | yes | yes | yes | | | | | | | | | | | Monad | yes | yes | | | | | | | | | | | | HyperEVM | yes | yes | | | | | | | | | | | | Solana | yes | yes | yes | yes | yes | yes | yes | yes | yes | yes | | | Trades are kept 24 hours and minute buckets 48 hours. A partial pair is measured on its verified routes only. A tracked pair can still be down. `coverage` in [`GET /v1/alert-capabilities`](https://traktor.fun/docs/alerts.md#get-v1-alert-capabilities) says whether each pair is live, stale or down: read it before you take an empty answer to mean there were no trades. An answer built from the trades traktor captures, whether a market, token, trader, stock board or signal answer, carries `provider_discovered_partial` when its scope takes in a pair marked partial, even while that pair is live. ## The flow filter The stream reads these keys from a subscription's `filter`. | Parameter | In | Type | Required | Default | Bounds | Description | | --- | --- | --- | --- | --- | --- | --- | | `v` | body | integer | no | | 1 | Grammar version; send 1, or leave it out. | | `windowMinutes` | body | integer | no | 60 | 1–1,440 | How old by block time a trade may be and still match. | | `maxLagSeconds` | body | number | no | 3600 | 0–86,400 | Drops a row whose `ingestedAt` trails its `blockTime` by more; `null` keeps every row. | | `chains` (or `chain`) | body | list | no | | solana, robinhood, bnb, base, arc, arbitrum, ethereum, monad, hyperevm, elysium | Chains to include, a JSON array or one comma-separated string; empty means all. A name outside the vocabulary is refused. | | `platforms` (or `platform`) | body | list | no | | fomo, gmgn, pump, axiom, coinbase, padre, maestro, bloom, trojan, bonkbot, bankr, photon | Apps to include, a JSON array or one comma-separated string; empty means all. A name outside the vocabulary is refused. | | `side` | body | enum | no | all | all, buy, sell | Which side of the trade. | | `minUsd` | body | money | no | none | | The smallest trade in USD; a row with no USD value never matches. | | `maxUsd` | body | money | no | none | | The largest trade in USD; a row with no USD value never matches. | | `tokens` (or `token`) | body | list | no | | up to 50 items | Token addresses; empty means any. | | `wallets` (or `wallet`) | body | list | no | | up to 50 items | Wallet addresses; empty means any. | - A list is a JSON array, or one comma-separated string, as in `"bnb,base"`. - `chains` and `platforms` take the lowercase names listed above, matched exactly. Any other name, such as `polygon`, `BNB` or `uniswap`, is refused rather than dropped: a dropped name would answer a different filter, every chain when it was the only name. The refusal is `filter_invalid`, with `detail.pointer` at the key you sent: `/filter/chains`, or `/filter/chain` if you spelled it so. - `tokens` and `wallets` may also be spelled `token` and `wallet`, and `chains` and `platforms` `chain` and `platform`. - Each key is read once. Both spellings of one key, such as `chain` with `chains`, are refused whatever either holds, empty or `null`: `filter_invalid`, with `detail.pointer` at the plural, `/filter/chains`. A key repeated inside one JSON object is not refused: its last value is read, so send each key once. - A key the grammar does not know is refused with `filter_invalid`. - EVM addresses are lowercased before they are matched. Solana addresses keep their case, so send them exactly as written. - `minUsd` and `maxUsd` are exact dollars: `300` is $300, and `k`, `m` or `b` scales it, as in `5k`. A minimum above the maximum is refused with `filter_invalid`. - `windowMinutes` bounds block time: the stream judges each trade as it arrives and leaves out one whose block is older than the window. - `maxLagSeconds` applies even when you leave it out: its default, shown above, drops a row stored more than that many seconds after its block. Send `maxLagSeconds: null` to keep every row. It cuts by age and says nothing about whether a chain is live; `coverage` in `GET /v1/alert-capabilities` does. - The keyless public market's market keys read names leniently: they ignore a chain or app name they do not know, so `chain=polygon` there answers for every chain ([Public market and search](https://traktor.fun/docs/public-market.md#get-v1-public-market)). ## What a filter scores Each subscription is weighed by its filter: a filter scores 1 for each of `chains`, `platforms` and `side` it sets, and 2 for each of `minUsd`, `maxUsd`, `tokens` and `wallets` it sets and for a `maxLagSeconds` number other than its default; it scores at least 1. A connection's subscriptions together may not score more than the plan's filter score: a `subscribe` that would answers `filter_too_broad`. A `tokens` or `wallets` list longer than the table allows answers `filter_invalid`, and one within it but longer than the plan's addresses per list answers `filter_too_large`. `GET /v1/meta/filters` publishes the rule under `cost.ws`. [Plans and limits](https://traktor.fun/docs/plans.md) shows each plan's filter score. ## Market filters `GET /v1/market` and its views take a grammar of their own, with windows, screens and launchpads, described [with the views](https://traktor.fun/docs/market.md#market-filter).
