FAQ · Reamer Research and Reamer Server: what they are and who they fit

Can I paper trade before going live?

Yes, by pointing your Reamer Server connector at your broker's paper or demo account. The server handles paper and live orders the same way, and the licence allows both. The kit's in-memory paper broker only checks that your server is wired up correctly; it fills every order instantly at a made-up price, so it is not a market simulation.

Three stages of testing

  1. Wiring check, with the kit's paper broker. An accept-all gate and a broker that fills in memory, in C++ and Rust. It confirms your program starts, takes orders and returns fills. It tells you nothing about how your strategy would trade.
  2. Session check, with the kit's simulated FIX venue. It lets you test your FIX session and connector, logon through to fills and rejections, before you connect to anyone else.
  3. Paper trading, at your broker. Point your connector at the broker's paper or demo account, if it offers one. Prices, fills and rejections then come from the broker. Nothing in Reamer Server changes when you later switch to the live account. Brokers usually simulate paper fills themselves, often more kindly than the real market, so this stage tests your system more than your strategy's profits.

Running paper and live side by side

A second instance on the same machine can run against a paper account, with its own socket, event bus and monitoring port. The two cannot share them. Reamer Server has no built-in switch for this; you set it up in configuration.

Licensing

The licence does not restrict paper or live trading, and a 30-day trial key is a full paid licence on the same terms. A seat is one machine, so an instance on another machine needs its own seat. See pricing.

Reamer Research has no paper or live mode; it runs backtests only. See Which brokers does Reamer Server connect to? and What is Reamer Server?

Next questions

What does it take to move from Reamer Research to Reamer Server?Your trading logic carries over; the code around it does not. You build a pre-trade gate, a broker connector and a strategy process once per deployment, map instrument indexes to names, and keep indicators as running state. No configuration, data file or cost setting carries across, and nothing converts the strategy for you.Which brokers does Reamer Server connect to?Any broker you write a connector for. Reamer Server ships no ready-made broker connection. You write the connector against its C interface, in C, C++, Rust or Go, over whatever API your broker offers. The kit includes an in-memory paper broker and a worked FIX 4.4 example run against a simulated venue.How long does integration take?In uncut recordings, Claude Code working only from the kit documents integrated Reamer Research in about 13 minutes and Reamer Server in about 19, through to a simulated fill for Reamer Server. The Reamer Server kit puts a person's first simulated trade at a few hours. Going live at a real broker takes longer, because the broker's protocol details, session recovery and certification are your work.What results and metrics does a run produce?A Reamer Research run produces 31 summary metrics, every closed trade, every fill and every order with its outcome, as one schema-versioned JSON document. From Python the binding returns less, the main profit and cost totals and the closed trades, so the full set comes through the C interface.

Every answer here restates the documents that ship in the kit, which are authoritative. All questions.
