# NinjaTrader 8 Custom Order Flow Delta Alert Indicator ## Project Overview I am looking for an experienced **NinjaTrader 8 / NinjaScript / C# developer** to create a simple, reliable, real-time **Order Flow Delta Alert Indicator**. I currently use **BellTPO / TPO Order Flow** and want a separate custom indicator that generates alerts when Delta reaches predefined levels. ## Main Requirements ### BUYING DELTA ALERT Trigger an alert when: **Delta >= +450** ### SELLING DELTA ALERT Trigger an alert when: **Delta <= -450** The thresholds must be user-adjustable from the indicator settings. For example: * Positive Delta Threshold: **450** * Negative Delta Threshold: **-450** ## Alert Features The indicator should provide: 1. Sound alert 2. NinjaTrader popup alert 3. Chart marker when the threshold is reached 4. Optional alert message 5. Separate ON/OFF switches for Buy and Sell alerts 6. User-adjustable Delta thresholds 7. Real-time alerts without waiting for the candle to close ## Important Real-Time Requirement The alert should trigger as soon as Delta reaches or crosses +450 or -450 during the active candle, if technically supported by the underlying Delta data. I do not want the alert to wait until the candle closes. ## Example If the current Delta is: +300: No alert +449: No alert **+450: Buy alert** +600: No repeated alert unless Delta resets or crosses the threshold again according to the agreed logic. Similarly: -300: No alert -449: No alert **-450: Sell alert** -600: No repeated alert unless Delta resets or crosses the threshold again. ## BellTPO Compatibility I use **BellTPO / TPO Order Flow on NinjaTrader 8**. The custom indicator should work independently and must not modify or decompile BellTPO proprietary code. The developer should use the appropriate NinjaTrader Order Flow or Delta data available to the indicator. ## User Settings Please include settings such as: * Positive Delta Threshold: 450 * Negative Delta Threshold: -450 * Enable Buy Alert: Yes/No * Enable Sell Alert: Yes/No * Sound Alert: Yes/No * Popup Alert: Yes/No * Chart Marker: Yes/No * Alert sound selection * Customizable alert message ## Testing Before final delivery, the indicator must be tested in: * NinjaTrader 8 * Real-time market data * Market Replay or historical tick data, where applicable The developer should provide a short demonstration showing: **+450 Delta: Buy alert** **-450 Delta: Sell alert** ## Deliverables I require: 1. Complete NinjaTrader 8 indicator 2. Full **NinjaScript/C# source code (.cs)** 3. Compiled version, if applicable 4. Installation instructions 5. Settings and configuration instructions 6. Basic troubleshooting instructions 7. Demonstration and testing confirmation ## Important This is an **alert-only indicator**. It must not automatically place trades. I will not provide proprietary BellTPO source code. The solution must be developed without modifying, decompiling, or copying proprietary BellTPO code. ## Developer Requirements Please apply only if you have experience with: * NinjaTrader 8 * NinjaScript * C# * Order Flow * Cumulative Delta * Footprint or Volumetric data * Bid/Ask Delta * Real-time alerts ### When submitting your proposal, please provide: 1. Your NinjaTrader 8 experience 2. Examples of previous Order Flow or Delta indicators 3. Whether you have worked with Cumulative Delta or Volumetric Bars 4. Estimated completion time 5. Fixed project price 6. Confirmation that you will provide the complete source code ## Budget Please provide your **best fixed-price quotation** for this project. I am looking for a developer who can deliver a **simple, stable, and accurate Delta alert indicator**, rather than a complicated automated trading system.

Your NinjaTrader Delta alert will fail if it polls data on bar close instead of subscribing to real-time OnMarketData events. This creates a 5-60 second lag where you miss critical Delta spikes during high-volume candles. Quick questions - are you tracking cumulative Delta per session or resetting per bar? And does your BellTPO feed expose Delta via NinjaTrader's native OnMarketData or does it require a custom data series? Here is the architectural approach: - NINJATRADER 8 ONMARKETDATA: Hook into real-time tick events to calculate Delta instantly without waiting for bar close, ensuring sub-second alert latency. - C# ALERT LOGIC: Implement threshold crossing detection with hysteresis to prevent alert spam when Delta oscillates near +450/-450 boundaries. - NINJASCRIPT SETTINGS: Build user-adjustable parameters for thresholds, sound files, popup toggles, and chart markers with full source code delivery. I've built 4 custom NinjaTrader indicators for algorithmic traders, including a Footprint Delta divergence tool that processes 10K ticks/second without lag. Let's schedule a 15-minute call to confirm your BellTPO data structure before I architect the solution.

Hello, I will develop your custom Order Flow Delta alert indicator for NinjaTrader 8 in C#. I will write a standalone NinjaScript indicator that subscribes to real-time tick and volumetric data to calculate bid/ask Delta on every tick of the active candle. The script will compare the live Delta against your user-defined positive and negative thresholds, instantly triggering sound alerts, popups, and chart markers without waiting for the bar to close. I will build reset logic to prevent repetitive alert spam during the same move. The indicator will run independently alongside BellTPO without touching or modifying any third-party code. Finally, I will test the indicator in Market Replay and live data to ensure reliable execution, and deliver the complete source code with installation and troubleshooting documentation. 1) Which specific tick data feed or NinjaTrader Order Flow Volumetric license do you currently have active? 2) What specific visual shapes or colors do you prefer for the chart markers when alerts trigger? 3) Should the alert reset occur when Delta drops back below the threshold or only when a new candle opens? Thanks, Bharat

Delta alerts sound simple on paper but the real-time part is where most people get it wrong — if you build it off OnBarUpdate you'll get triggers only on bar updates or closes depending on your calculation mode, not the instant delta crosses 450. I'd hook into OnMarketData directly so it reacts tick by tick, with a fired/reset flag per bar so you don't get spammed every tick after it crosses. Worked with cumulative delta and volumetric bars on NT8 before, so the logic itself isn't the hard part Are you running Rithmic/CQG with the volumetric data feed, or just standard ticks? Changes whether I pull delta from NT8's built-in series or build it manually either way works, just want to scope it right before quoting final. Can have something testable on replay in 5-7 days. $180 flat, full source code, nothing touching BellTPO.

Hi, I can build this as a clean NinjaTrader 8 / NinjaScript C# indicator focused specifically on reliable real-time Delta threshold alerts. My background includes algorithmic trading-system development, NinjaTrader/C#, MT5, TradingView, automated execution logic, custom indicators, backtesting, and risk/order-flow workflows. For your project, I would implement: • Configurable positive/negative Delta thresholds • Real-time intrabar threshold detection • Buy/Sell alert enable switches • Sound and popup alerts • Chart markers • Custom alert messages • Logic to prevent repeated alerts while Delta remains beyond the threshold • Market Replay / tick-data validation • Full NinjaScript/C# source code • Installation and configuration instructions I understand this must work independently of BellTPO and must not modify or decompile proprietary code. I would use the appropriate NinjaTrader Order Flow/Volumetric Delta data available to the indicator. I would first validate the Delta source and intrabar behavior, then build the alert layer and test threshold crossings under Market Replay. Bid: ₹36,000 INR Delivery: 4–6 days Full source code will be included.
