Custom NinjaScript development for NinjaTrader 8 — indicators, automated strategies, and MT4/MT5 platform conversions. Built by an algorithmic trading developer with 13+ years of production experience across MetaTrader, NinjaTrader, and other professional platforms.
What You Get
- Fully compiled NinjaScript indicator ready for NinjaTrader 8 deployment
- Custom automated strategy with your entry, exit, and risk logic
- Platform conversion package: MT4/MT5 MQL code rebuilt as equivalent NinjaScript
- Full .cs source files — you own the code outright, no license restrictions
- Deployment walkthrough and support window for questions and adjustments
How It Works
- Specification: You describe what the indicator or strategy should do — entry signals, display logic, alerts, order management rules. I send a written specification to confirm scope before any code is written.
- Development: I build the NinjaScript in C#, handling the API constraints that generic development misses — multi-timeframe data feeds, `BarsInProgress` tracking, `State.Historical` vs `State.Realtime` branching, and the behavioral differences between bar-close and tick-based execution.
- Testing: I test against NinjaTrader 8’s Strategy Analyzer and verify live chart behavior. Known edge cases are covered before delivery — not discovered by you afterward.
- Delivery: You receive the .cs source files with documentation. Thesupport window covers deployment questions and minor adjustments within the agreed specification.
Who This Is For
Good fit:
- Futures and forex traders who want to automate a defined strategy on NinjaTrader 8
- MetaTrader users migrating to NinjaTrader who need existing MQL4/MQL5 indicators or EAs rebuilt in NinjaScript
- Traders with AI-generated NinjaScript code that compiles but produces wrong signals or crashes in live trading
Not the best fit:
- Traders without a defined strategy — I implement what you specify, not strategy research
- Projects requiring third-party DLL integration — these add licensing and security complexity that affects scope significantly; raise this upfront so it can be scoped correctly
What Makes This Different
NinjaScript development looks straightforward until you hit the platform-specific constraints that generic freelancers miss. Multi-timeframe indicators on NinjaTrader behave differently depending on whether you’re accessing the primary series or a secondary data feed. `BarsInProgress` needs explicit tracking when indicators span multiple timeframes. The distinction between `State.Historical` and `State.Realtime` isn’t optional — ignoring it produces indicators that render correctly on historical bars but give wrong values in live markets.
I’ve migrated MetaTrader 4 strategies to NinjaTrader for several clients. A literal port almost always fails because the event models are structurally different: MQL’s `OnTick()` fires on every price update, while NinjaTrader’s `OnBarUpdate()` runs per-bar by default. Replicating the intended behavior requires adapting the logic, not translating it line by line.
If you’re coming from MetaTrader, I can read your existing MQL4/MQL5 source and rebuild the equivalent functionality in NinjaScript with the behavioral guarantees that matter in live markets.
Pricing
Custom NinjaScript indicators start at $150. Automated strategies with order management and risk logic typically range $300–$1,200 depending on complexity. Platform conversions from MT4/MT5 to NinjaTrader start at $300.

Frequently Asked Questions
Does NinjaTrader 8 support the type of custom development you’re describing?
Yes. NinjaTrader 8 exposes a full NinjaScript API in C# covering indicators, automated strategies, order flow tools, and chart objects. Everything accessible through the platform UI can be extended programmatically. The only practical limitation is DLL-based external connections, which add security and licensing complexity and are scoped case by case.
I have an existing MQL4 indicator — can you port it to NinjaTrader?
Yes. I read the existing MQL4 or MQL5 source code directly and rebuild the equivalent logic in NinjaScript. This isn’t a mechanical translation — the event models are structurally different, so the logic has to be adapted to work correctly in NinjaTrader’s bar-close and real-time tick model. The result behaves equivalently to the original without the behavioral gaps that a literal line-by-line port creates.
How long does a typical NinjaTrader indicator project take?
Most custom indicators are delivered within 3–5 business days from confirmed specification. Automated strategies with order management take 5–10 business days. Platform conversions depend on the complexity of the source code — a timeline is included in the quote.
What version of NinjaTrader do you develop for?
All new development targets NinjaTrader 8 (NT8), the current supported version. If you need NT7 compatibility for a legacy deployment, raise it upfront — the API differences between NT7 and NT8 are significant and affect scope.
Do I get the source code?
Yes. Every project includes full .cs source files. You own the code outright — no recurring fees, no license keys, no restrictions on use or modification. The source code is yours to keep, modify, and hand to another developer if needed.
