Signals API Documentation | TrendTrader Pro

Authentication

Every request carries your API key as a bearer token. Generate the key on the API page in the app (left menu). It is shown once: we store only a hash, so a lost key cannot be recovered, only replaced.

HTTP header

Authorization: Bearer ttp_live_…

One live key per account. Generating a new key revokes the old one immediately.
Pro plan required. Calls need an active Pro subscription; revoking a key works on any plan.
Keep it server-side. Never ship the key in a browser, a mobile app or a public repository.

Endpoint

One endpoint returns the current daily trend and the latest intraday flip for every market we cover, or for the symbols you name.

GETJSON

GET https://app.trendtrader.pro/api/v1/signals

The API answers on app.trendtrader.pro only. Any other hostname answers 404.

Parameters

Both query parameters are optional. Omit them to receive the whole feed.

Parameter Meaning

symbol Comma-separated list of up to 50 symbols, for example EUR/USD,BTC/USD,AAPL. Omit it for the whole universe.

since ISO-8601: a date (2026-10-08) or a datetime with a zone (2026-10-08T00:00:00Z). Daily rows keep trends whose fired_at date is on or after the calendar date you wrote (the 2026-10-08 part, in your own zone; it is never shifted to UTC). Intraday rows keep flips at or after the exact timestamp. Daily flips are detected hours after the bar closes, so poll daily with a one-day overlap. Daily between and awaiting rows have no fired_at and are left out whenever since is set.

Parameter	Meaning
`symbol`	Comma-separated list of up to 50 symbols, for example `EUR/USD,BTC/USD,AAPL`. Omit it for the whole universe.
`since`	ISO-8601: a date (`2026-10-08`) or a datetime with a zone (`2026-10-08T00:00:00Z`). Daily rows keep trends whose `fired_at` date is on or after the calendar date you wrote (the `2026-10-08` part, in your own zone; it is never shifted to UTC). Intraday rows keep flips at or after the exact timestamp. Daily flips are detected hours after the bar closes, so poll daily with a one-day overlap. Daily `between` and `awaiting` rows have no `fired_at` and are left out whenever `since` is set.

Fields

asset_class: One of Forex, Crypto, Stocks, ETFs, Indices, Commodities.
state: buy, sell, between (the dashboard's "Between Zones" row) or awaiting ("Awaiting first signal"). A row is the market's current state, however old; use fired_at for its age. between and awaiting rows carry no trade: their fired_at is null and trend_age_days is 0.
trend_age_days: Daily rows only. The number shown beside the daily row in the dashboard: the age of the trend structure the row is anchored to. It is not the days since fired_at.
fired_at: Daily: the date the current trend fired, or null for between and awaiting rows. Intraday: the exact flip time.
as_of: Daily rows only. The last daily bar the row was evaluated on.
intraday: The most recent intraday flip per market on record, with its real fired_at. The in-app intraday feed additionally hides markets with no fresh intraday data.

Limits and terms

Caching. The unfiltered feed is cached at our edge for 60 seconds; polling faster than that returns the same data. Filtered requests are not cached.
No client caching. Responses carry Cache-Control: no-store. Never cache them yourself.
Polling cadence. Daily flips land hours after the daily bar closes; one call a day with a one-day since overlap keeps you current. The feed is each market's current state, not an event log: a flip replaced before your next call is not kept. Intraday flips arrive through the session, so poll at the 60-second cadence or slower.

Your own use only. The feed is for your own trading decisions and your own tools. Reselling, rebroadcasting or publishing it is not permitted. See the Terms of Service.

Disclaimer
