Why FastTick
Market data access, done properly
We do not resell data vendor accounts. We sell a stable, metered and operable market data service. We handle the engineering; you focus on your strategy.
One token for everything
After purchase you get a single opaque token for the request header or auth frame. No key/secret signing, no token exchange logic to maintain.
Subscription-level limits
QPS, WebSocket connections, symbol count and history depth are defined by the plan. Quotas are counted per subscription and shared by its tokens; over-limit requests return a standard 429.
Standardised fields
Prices and sizes are strings carrying the symbol precision, timestamps are UTC milliseconds and changes are signed percentages — no float drift, no cross-market ambiguity.
Grace period, not a hard cut-off
When a subscription expires it enters a grace period with read-only access and renewal reminders. Service stops only after that; renewing restores the same token immediately.
A closable commercial loop
Orders, payments, refunds, invoices and monthly statements are all recorded. Corporate transfers and offline refunds are supported, so finance and audit stay clean.
Three steps
From signup to your first quote in half an hour
No collectors to deploy and no exchange quirks to handle. Pick a plan, get a token and call the API.

-
02
Pay and get activated
The subscription takes effect on payment; view or reset the token in the console.
-
03
Integrate with the docs
Verify with a single REST call, then subscribe to symbols with a WebSocket auth frame.
