Your NinjaScript strategy deserves production-grade infrastructure
Most NinjaScript strategies work in backtests and sim, then fail silently in live trading. We harden your strategy with proper state management, an independent risk layer, and real-time monitoring so you are trading a reliable system, not hoping nothing breaks.
What breaks in NinjaTrader production
These are not edge cases. Every trader running a NinjaScript strategy live hits at least two of these within the first month.
Connection drops break your strategy
NinjaScript runs fine in sim, then loses state when a connection drops mid-session. After reconnect, your strategy holds a phantom position or fires duplicate orders. There is no built-in recovery logic.
No real risk layer
NinjaTrader's native ATM strategies are static. There is no daily loss limit that halts trading automatically, no max-position enforcer, and no kill switch you can trigger remotely when a strategy misbehaves at 3am.
Multi-account is painful
Running the same strategy across two accounts (a funded account and a personal account) means duplicating configurations and hoping they stay in sync. One wrong setting and the accounts diverge.
Data gaps and session boundaries
NinjaTrader's historical data has gaps around rollovers, holidays, and session boundaries. Indicators that reference prior sessions can silently calculate on bad data, producing wrong signals.
Unreliable alerts
The built-in alert system sends Windows toast notifications that miss if the machine is locked. Email alerts are slow. There is nothing that pages you instantly when a position goes wrong.
Deliverables
What D&T Systems builds for you
Each engagement is scoped to your specific setup. These are the building blocks we combine based on what your strategy needs.
Production-hardened NinjaScript
Full state machine rewrite of your strategy with proper reconnection logic: position reconciliation on reconnect, order deduplication, and heartbeat monitoring. Works correctly across session breaks and broker disconnects.
Risk middleware
An independent risk layer that sits outside NinjaTrader: daily loss limits, max open position limits, drawdown-from-peak halts, and a remote kill switch you can trigger from a web dashboard or Telegram message.
Multi-account management
Single strategy instance that fans out orders to multiple NinjaTrader accounts simultaneously, with per-account sizing, per-account risk limits, and a unified P&L view across all accounts.
Data quality layer
Futures-aware data pipeline that handles continuous contract construction, rollover gap-filling, session filtering (RTH vs ETH), and stores clean tick/OHLCV data in TimescaleDB for repeatable backtests.
Real-time monitoring and alerting
Prometheus metrics exported from the strategy, Grafana dashboards for live P&L and risk metrics, and instant Telegram/Slack/email alerts for fills, errors, daily limit triggers, and anomalous behavior.
Operations dashboard
A lightweight web UI showing live position, daily P&L, risk usage, recent fills, and strategy health, with the kill switch integrated. No more watching NinjaTrader windows to know if things are running.
Instruments
Futures markets we know
Primary focus is CME equity index futures. We have direct live trading experience on ES and NQ (micro and full contracts) and understand the nuances of RTH vs ETH sessions, rollover timing, and margin behavior.

Process
How an engagement works
From the first call to a live hardened system typically takes two to four weeks depending on the complexity of your strategy.
Diagnostic call
30 minutes to understand your current NinjaScript setup, live trading history, risk parameters, and what has broken in production.
Architecture review
We review your existing NinjaScript code, identify fragile patterns, and produce a written scope: what gets hardened, what gets rebuilt, and what infrastructure gets added.
Build and test
Development in a staging environment with a replayed data feed. Strategy behavior is verified against historical sessions including connection drop simulations.
Parallel live validation
The hardened strategy runs alongside your existing setup in paper or small-size live mode. We compare fills and P&L to confirm parity before cutting over.
Handoff and support
Full documentation, runbooks for common failure modes, and a support window so you are not debugging a production issue alone.
Why trust us
Built by someone who has traded ES and NQ live
D&T Systems was founded by an engineer who has been actively trading ES and NQ futures on NinjaTrader for over a year, with real capital, not just sim. That means we understand the difference between a strategy that works in Replay mode and one that handles real session opens, news spikes, and connection drops at market open.
