GRAYBOOK TECHNOLOGIES
Services
Three services that work alone or together. Start with a strategy and a laptop, finish with a rack beside the matching engine, with the same engineers and the same code the whole way.
We build production trading systems on open-source engines such as NautilusTrader, with one codebase that behaves the same in a backtest as with real money. Everything we write is yours, with no runtime to rent.
//@gbs 1// Backtest an EMA cross with slippage and feesindicator("Run Backtest", overlay = true)input float fee = 2.5, "Fee per side"series float fast = ema(close, 9)series float slow = ema(close, 21)var float entry = navar float pnl = 0if crossover(fast, slow) { entry = close + mintick }if crossunder(fast, slow) and not na(entry) { pnl = pnl + close - entry - fee * 2 entry = na}if islastbar { table_cell(table(top_right), 0, 0, "Net " + str(pnl, 2)) }Turn research notebooks into event-driven strategies in Python or Rust, with tests that run on every change.
The same engine, clock and order logic in research and production, so what you tested is what trades.
Connect the broker, exchange or data vendor your strategy needs, even if the engine doesn’t support it yet.
Vendor and historical data organised for fast, repeatable backtests and large parameter sweeps.
Replay any trading session event by event to debug a fill, answer an auditor or prove a fix.
Production rollout, monitoring and on-call support, on our servers, in colocation or in your own data center.
Whatever you trade, wherever you’re starting from.
Dedicated-resource Windows and Linux servers in data centers close to the exchanges. Install your platforms, load your charts and automated strategies, and connect by remote desktop from a laptop, tablet or phone. Your trading keeps running when your home internet doesn’t.

Choose the data center closest to where your orders go.
Install any Windows or Linux platform, broker or data feed.
Rack space in the data centers where exchanges run their matching engines. We handle power, cross-connects, market data and the network between trading centers, then monitor every packet with nanosecond timestamps. Run it yourself, or let our operations team run it for you.
Half racks to private cages, redundant power and remote hands on site.
Direct physical connections to order entry and market data handoffs.
Direct exchange feeds or normalized data, delivered into your rack.
Private links between trading centers for cross-venue strategies.
Packet capture and tick-to-trade measurement to prove and tune performance.
Server and FPGA procurement, installation and 24/7 operations.
