I want a custom NinjaScript 8 study that builds a true delta-volume bar view, not just cumulative delta. The core logic has to calculate bid-ask volume in real time, aggregate it into bars based on delta size, and repaint nothing after the tick is closed. Real-time performance is critical, yet I also need the study to pull and replay historical data so the same calculations work on past sessions for strategy-testing and market-replays. Visuals matter: every bar should be color-coded automatically (e.g., green for positive delta, red for negative, neutral shade for flat), with settings exposed so I can tweak the exact RGB values later. I often stack indicators, so please structure the output to publish public plots and series that other scripts can subscribe to; think of it as plug-and-play with order-flow or footprint tools already on my charts. Deliverables • Fully commented .cs file compatible with NinjaTrader 8 • Simple parameters panel (bar size/threshold, colours, session template) • Step-by-step install and test instructions • Short video or screenshots showing both live ticking data and historical playback functioning as expected Acceptance will be based on: 1. Tick-by-tick real-time delta accuracy cross-checked against the SuperDOM. 2. No memory leaks or noticeable platform slow-down after several hours of market streaming. 3. Historical backfill identical to live output when reloaded.

Hi, I can build a NinjaTrader 8 study that creates true delta-volume bars from bid/ask volume, not just a cumulative delta line. The logic would process tick data, classify volume at bid/ask, aggregate bars by delta threshold, and avoid repainting once a tick/bar is closed. I’d structure it for both real-time and historical use, using NinjaScript’s tick replay/historical data handling so the same calculation path can be tested on past sessions and market replay. Performance would be a priority: efficient series updates, controlled object creation, and careful memory handling so it can run for long sessions without slowing NT8 down. For visuals, I’d expose parameters for delta threshold/bar size, session template behavior, positive/negative/neutral colors, and any display options. I’d also publish public plots/series so other indicators or strategies can read the delta bar values cleanly. Deliverables would include the commented `.cs` file, install/test instructions, and screenshots or a short demo showing live ticking and historical playback. Question 1: Do you want the delta bars drawn in a separate panel, or overlaid on the main price chart? Question 2: Which market/instrument will you use for acceptance testing against the SuperDOM? Regards, Houssame

This is more than a custom chart paint job. The hard part is keeping live bid/ask classification, historical tick replay, and the generated delta bars aligned so a reload doesn’t produce a different chart. I’d build it as a NinjaTrader 8 study around tick-level processing, with fixed delta thresholds, no post-close mutation, exposed color parameters, and public Series/plots for other scripts to read. One thing to confirm first: does your data feed provide historical bid/ask tick data with Tick Replay enabled? Without that, live delta can be accurate but historical reconstruction won’t truly match SuperDOM-style bid/ask volume.

Hi, Delta-volume bar construction and tick-by-tick bid-ask aggregation are concepts I work with daily in trading system development—and NinjaScript 8 is C#, which is my native environment for indicator work. Here's my approach for the core logic: Delta bar engine: Separate bid and ask volume on each tick using GetCurrentAsk()/GetCurrentBid() comparisons Aggregate into bars based on delta threshold (not time), closing the bar when delta size is hit No repaint after bar close—delta is locked once the bar is sealed Historical backfill: Same calculation path for both live ticks and historical replay, so strategy-testing and market-replay produce identical output to live—verified against SuperDOM Visuals + interoperability: Color-coded bars (positive/negative/flat delta) with full RGB parameters exposed in the settings panel Public plots and series published via NinjaScript's AddPlot()/AddLine() API so other scripts can subscribe—plug-and-play with your existing orderflow/footprint tools Deliverables: fully commented .cs file, parameters panel (bar size, threshold, colours, session template), install/test instructions, and screenshots showing live tick and historical playback matching.

Hello, I have developed many NinjaTrader 8 order flow, delta, footprint, and custom bar type projects, including studies that process tick-by-tick bid/ask volume with accurate historical replay. I understand the importance of keeping the calculations identical between live data and historical playback while maintaining high performance. I can build this study with clean, modular code that publishes public plots and series, making it easy to integrate with your existing indicators and strategies. The parameters for delta threshold, colors, session template, and other settings will all be exposed through the indicator inputs. I will also ensure the study is optimized for long market sessions without memory leaks or performance issues. I have a couple of questions: 1. Which market data provider are you using (CQG, Rithmic, Kinetick, Interactive Brokers, etc.)? This affects the availability and quality of historical bid/ask tick data. 2. Should the delta bars reset at each session, or should there be an option for continuous accumulation across sessions? I can provide the fully commented NinjaScript source, installation guide, and demonstration showing both live and historical replay working correctly. I can also share a recent NinjaTrader project that demonstrates the quality of my work.

My implementation will start by processing tick-by-tick market data and classifying each trade as bid or ask to calculate the true delta in real time. Instead of using cumulative delta, the indicator will build independent delta bars based on a configurable threshold, locking each completed bar so no repainting occurs. For historical sessions, I'll reconstruct the same calculations using Tick Replay or historical bid/ask data when available, ensuring the output remains as consistent as possible with live trading. I'll optimize the processing logic to keep memory usage low and maintain smooth performance during extended market sessions. The indicator will expose its calculated values through public Series and Plots, making it easy for other NinjaScript indicators or strategies to consume the data. Finally, I'll add a configurable settings panel for thresholds, colors, and session templates, then validate the results against the SuperDOM and provide installation instructions along with a demonstration of both live and historical playback.
