Steam chasing with Pinnacle drop alerts

Answer: steam chasing means betting at another book after a sharp price move at Pinnacle, before that book adjusts. The workflow is: detect the Pinnacle move, check that the market is liquid (maxStake), compare with the price still on offer elsewhere, and decide fast. PinnFeed gives you the detection side: GET /v1/drops returns the biggest Pinnacle price drops over the last N minutes on any plan, and on Builder every price change is pushed over the WebSocket.

1. Detect the move#

curl -s "https://pinnfeed.io/v1/drops?sport=soccer&minutes=5&min_pct=4&limit=20" \
  -H "x-api-key: ps_live_your_key" | jq '.drops[] | {home, away, market, outcome, from, to, dropPct, movedAt}'

from is the highest price in the window, to the current one, dropPct the fall in %. minutes is 1–60, min_pct 0.5–90.

2. Filter noise#

• Require a liquid market: look up the market and skip it if maxStake is under about 100.
• Prefer main lines (main=true) and leagues you know.
• Ignore moves right after a line is first posted; early prices are often adjusted.

3. Act within your own rules#

Compare the offer at your book with Pinnacle's new price and fair. If the other book has already moved, there is nothing to chase. Speed matters: Free data is 30 s delayed, Hobby is real-time REST (2 req/s), and Builder pushes changes over the WebSocket. PinnFeed does not publish a latency figure; measure it yourself (latency honesty).

Know the downsides#

• Soft books often limit accounts that consistently bet into stale lines.
• A drop can be a correction of an error, news, or a single large bet; not every move holds.
• Follow your book's terms and local law.

Questions people ask#

Is /v1/drops enough or do I need the WebSocket?#

/v1/drops is a good start and works on every plan. For the fastest reaction, Builder's WebSocket pushes each change as PinnFeed receives it.

What drop size counts as steam?#

There is no fixed number; many people start around 3–5% within a few minutes and tune from their own results.

Does PinnFeed show where the other books are?#

No. It is Pinnacle-only; you bring the other price.
