Custom NinjaScript automated strategies, custom indicators, and advanced ATM execution systems built in C# for NinjaTrader 8. Engineered for futures, equities, and forex with tick-level Market Replay testing, Rithmic/CQG order routing, and strict prop firm compliance (Apex, Topstep) — delivered with complete source code ownership.
NinjaTrader 8 is the undisputed premier platform for algorithmic futures and US equities trading. Built on the modern Microsoft .NET framework, its native programming language — NinjaScript (C#) — gives algorithmic developers unconstrained access to object-oriented architectures, multi-threading, custom UI controls, and external C# libraries without the limitations of sandbox scripting environments.
Where NinjaTrader 8 truly shines is its institutional-grade Market Replay engine and Advanced Trade Management (ATM) framework. Traders can replay historical tick-by-tick Level 1 and Level 2 market depth data for contracts like the E-mini S&P (ES) and Micro E-mini Nasdaq (NQ) with exact real-world order fills, bid/ask spread dynamics, and queue position modeling. Delivered with 100% C# source code ownership.
From automated futures strategies and prop firm risk engines to custom order flow indicators — every project includes complete C# NinjaScript source code and setup documentation.
We build automated trading systems across all major retail and institutional environments. Explore our specialized development capabilities across other platforms.
Real systems. Institutional C# architectures. Every strategy delivered with full source code.
An intraday futures trader required an automated breakout and mean-reversion strategy for E-mini Nasdaq (NQ) and E-mini S&P (ES) contracts on NinjaTrader 8. The system needed to manage five funded $150k Apex Trader Funding accounts simultaneously, where a single intraday trailing high-water mark drawdown breach of $5,000 would instantly liquidate the accounts.
Engineered a high-performance NinjaScript (C#) strategy integrating order flow cumulative delta confirmation and automated Advanced Trade Management (ATM) multi-bracket exits. Built an autonomous account monitor that computes the intraday trailing threshold tick-by-tick, implements auto-breakeven trailing ladders, halts entries during FOMC/CPI news, and atomically flattens all open contracts before market settlement.
Passed all evaluation benchmarks across 5 accounts in 18 trading days. Currently active on funded live accounts with zero trailing drawdown infractions and an average order execution latency under 16ms.
