NinjaTrader development, done by trading system engineers
NinjaTrader is the most customizable retail futures platform there is — NinjaScript gives you full C# and .NET access to indicators, strategies, orders, and executions, with a Strategy Analyzer, Market Replay, and an ecosystem of thousands of add-ons on top. That power is also the trap. The gap between a Strategy Builder prototype and a strategy that trades a funded account unattended is real engineering: order handling that survives disconnects, logic that behaves identically on live ticks and historical bars, backtests that aren't quietly lying to you, and risk controls that respect your prop firm's drawdown rules to the dollar.
FintegrationFS is a fintech engineering studio, not a gig marketplace. Our engineers build automated trading systems professionally — signal engines, execution layers, and multi-account systems running live — and NinjaScript's C# foundation is our home language. 12+ years of fintech engineering, official technology partnerships with Alpaca and Plaid, US office, fixed-scope pricing.
What kind of NinjaTrader build do you need?
"NinjaTrader developer" covers five very different jobs — and quotes that don't distinguish them are guessing:
Custom indicators — your analysis, coded properly: efficient on every tick, correct on historical data, with clean plots and alerts.
Automated strategies — your rules turned into NinjaScript that trades unattended, with entries, exits, stops, and risk built in.
Strategy conversion — Pine Script (TradingView), thinkScript, MT4/MT5, or EasyLanguage logic ported faithfully to NinjaScript — including the parts that don't translate literally.
Add-ons and tools — custom windows, dashboards, risk consoles, and workflow tools using the AddOn framework.
Strategy hardening — you have a strategy that "mostly works"; we make it production-grade: connection recovery, order-state handling, logging, and prop-firm-compliant risk.
Not sure which yours is? That's the first thing we resolve in a free scoping call.
What our NinjaTrader developers build
Automated strategies that survive real markets. Managed or unmanaged order methods chosen deliberately, correct behavior on OnBarClose vs OnEachTick, position recovery after restarts, and a kill switch — because unattended means unattended, not unsupervised-until-it-breaks.
Custom indicators and order-flow tools. From simple signal plots to multi-timeframe, multi-instrument analytics — coded for performance so your charts stay responsive with a dozen instances loaded.
Faithful strategy conversions. Pine Script and MT4/MT5 ports where we translate intent, not just syntax — flagging the places where platform differences (bar timing, fill assumptions, session handling) would silently change your results, and resolving them with you before they cost money.
Prop-firm-ready risk layers. Daily loss limits, trailing drawdown tracking, and flatten-and-halt logic engineered to your funded account's exact rules — so the strategy protects the account even when the market doesn't cooperate.
Honest backtesting setups. Strategy Analyzer configured with realistic slippage and commissions, tick replay where bar data would flatter the results, and walk-forward optimization that resists curve-fitting — a backtest's job is to try to kill the strategy before the market does.
Multi-account and deployment infrastructure. Strategies replicated across accounts with per-account sizing, VPS deployment for 23/5 futures sessions, monitoring, and Telegram/Discord alerts on fills, rejections, and disconnects.
How we work — fixed scope, no surprises
Free scoping call (30 minutes). We map your rules, platform setup, and account structure — funded, personal, or both.
Specification you approve. Your strategy logic written out unambiguously before coding starts — most "the bot doesn't do what I meant" disasters die here.
Build with sim validation. Everything proves itself in NinjaTrader's simulation and Market Replay before your capital is involved.
Staged go-live and support. Reduced size at launch, monitoring from day one, source code and documentation that are yours.
What a NinjaTrader engagement looks like
A funded trader automates a proven manual setup. A discretionary order-flow entry with mechanical management becomes a NinjaScript strategy: exact entry conditions, ATM-style bracket management, and a risk layer tracking the prop firm's trailing drawdown in real time — flattening and disabling itself before a rule violation, not after.
A TradingView strategy moves home to futures. A Pine Script system with years of alerts behind it is ported to NinjaScript for direct execution — bar-timing and fill differences reconciled against the original, validated side-by-side on identical data before the switch.
A trading educator ships a toolset. A vendor's proprietary indicators rebuilt as licensed, performance-optimized NinjaScript add-ons with protected compiled assemblies — ready for distribution to a subscriber base without shipping the source.

NinjaTrader development FAQs
Will your strategy guarantee profits?
No — and run from anyone who says otherwise. We build faithful, robust implementations of your rules with risk controls that limit damage when the rules are wrong. We'll tell you honestly during scoping if the logic has structural problems — repainting signals, look-ahead bias, fill assumptions the live market won't honor — but edge is yours; flawless execution is ours.
Can you convert my TradingView (Pine Script) or MT4/MT5 strategy to NinjaTrader?
Yes — it's one of our most common builds. The critical part isn't the syntax, it's the semantics: bar timing, session boundaries, and fill logic differ between platforms, and a literal translation can produce different trades from the same rules. We port the intent, validate side-by-side against the original, and document every deliberate divergence.
Can I run this on a funded prop-firm account?
We build the risk layer to your firm's exact published rules — daily loss, trailing drawdown, position limits — with flatten-and-halt behavior that triggers before a violation. One honest caveat: automation policies vary by prop firm, so confirm yours permits automated execution; we'll build compliant either way, including semi-automated modes where full automation isn't allowed.
Will it run unattended? What happens when my connection drops?
That's precisely the engineering that separates production strategies from scripts: reconnection handling, order and position state recovery on restart, duplicate-order prevention, and alerting so you know within seconds — typically deployed on a Windows VPS so your home internet is never the weak link.
How realistic will the backtest be?
As honest as we can make it: real commissions and slippage, tick replay where intrabar sequence matters, out-of-sample and walk-forward testing rather than one optimized curve. If the strategy only works with zero slippage, you'll hear that from us — not from your account statement.
Is NinjaTrader still a safe platform to invest in after the Kraken acquisition?
Yes — Kraken acquired NinjaTrader in 2025 and it continues as a standalone platform with its FCM intact, now with a roadmap expanding across asset classes. NinjaScript and the add-on ecosystem remain fully supported; nothing about the acquisition changes how custom development works.
How long does a NinjaTrader project take?
A custom indicator: about a week. An automated strategy with risk layer: 2–4 weeks. Conversions, multi-account setups, or vendor-grade add-on suites: 4–8 weeks. Fixed price and timeline in the quote — sim validation included, never skipped.
Do you sign NDAs? Who owns my strategy and the code?
NDAs are standard before you tell us a single rule — strategies are the crown jewels. You own 100% of the source code and IP, delivered with documentation. We never reuse, resell, or repurpose client strategy logic.
