Backtester Desktop App- Sports Betting Data - NEW

@usmanbashir12100

Hello, I can build a clean, Windows desktop back-testing app that ingests your Excel bet-history, offers instant, on-the-fly filtering, and returns the sportsbook performance metrics you need — yield, ROI, P/L, max drawdown, streaks, odds-movement analysis, and interactive charts. The interface will be simple and focused: an import/file browser, persistent filter panels (league, team, odds ranges, opening vs closing movement, bookmaker averages, etc.), a results table, and live charts that refresh whenever you change a filter. You’ll be able to save and re-load filter configurations as named “Strategies”, export results, and run speedy back-tests across football, basketball, tennis and other sports. What I’ll deliver A production-ready Windows app with polished GUI (native or Electron → packaged EXE). Excel ingestion (batch import + mapping), robust parsing, and normalization. Real-time filtering UI: league, team, odds ranges, % odds movement, opening vs closing, bookmaker/average comparisons. Metrics & reporting: yield, ROI, P/L, max drawdown, hit rate, expectancy, and customizable date/league breakdowns. Interactive charts (equity curve, P/L histogram, odds-movement scatter, drawdown), plus CSV/XLSX export. Strategy save/load, basic logging, and user guide.

Hi, I can surely build using python streamlit for frontend.I am Software Engineer with 7 Years of experience.I would like to connect via chat to check the Excel data you have.

@skctechno

I am a windows desktop app specialist, with 20+ years experience. I have complete all my 72 projects with 100% completion rate, and all within time & budget. Excel and CSV are my playground, have created many data import and analysis projects. Just assign me the project and get it done ASAP. C# Winforms will be better for a stable and easy to maintain code. I can do all your forthcoming improvements and requirements for the project too. Best Regards.

@devendrathakur12

Hello, I built and customized large-scale desktop apps that read hundreds of thousands of rows and still feel light and fast. Looking forward to discuss your project in detail. I’m certified in desktop app dev, and I work a lot with C#/WPF and Python (PyQt). I can also do something extra for you that others often skip: I will make the whole app run as a single Windows .exe with no dependencies, no weird installs, and no broken paths later. Here is my simple plan: I will build a clean Windows app that loads your Excel files, applies your filters, and shows yield, ROI, max drawdown, P/L and more in real time. I will also create separate import scripts for each spreadsheet source, fix the two files that need automation, and convert your Pinnacle JSON data into clean Excel automatically. A few quick questions so I design it perfectly: Do you want charts to auto-update every time you change one filter? Should saved strategies also remember chart settings? How large can a single spreadsheet get on your side? Best regards, Dev S.

Hi Nikolaos, Thank you for considering my proposal for your project. With over 8 years of experience in Excel, I am confident in my ability to assist you with creating a Windows-based desktop app for back-testing sports-betting models using historical bet data. I have carefully read through the project requirements and am eager to discuss the details further with you in chat. Regards,

@rosscarter1011

Hello. Regarding the data ingestion engine, given the requirement to process 100k rows under 10 seconds, would you prefer we utilize Python with the Polars library (which is significantly faster than Pandas) for the backend calculation, or stick to a pure C#/.NET environment for tighter Windows OS integration? Also, for the Pinnacle API JSON-to-Excel conversion, do you require this to be a recurring background process or a manual trigger within the app? I will develop a high-performance Windows Desktop Application (preferably using Python/PyQt or C# WPF) that acts as a central hub for your betting strategy. I will structure the app with a modular 'adapter' system, where each Excel source has its own import script, allowing us to easily handle the unique formatting rules and the specific automation adjustments you listed for the two special files. The core calculation engine will be built to handle 'Max Drawdown', 'Yield', and 'ROI' in-memory, ensuring that when you toggle a filter (e.g., dropping odds or specific leagues), the charts and tables refresh instantly without lag.

Hi, I’ve helped build multiple data heavy desktop tools for sports modelling and betting analysis, including Excel-driven backtest engines, odds-movement analytics, and custom Windows apps for strategy optimisation. For your project I can deliver a clean Windows desktop application that imports your spreadsheets, applies complex filters instantly, and returns key metrics like ROI, yield, max drawdown, P/L and more with live-updating tables and charts. I’ll also create the separate import scripts for each data source, handle the JSON-to-Excel conversion for the Pinnacle API files, and implement the ability to save and load strategies. Performance is a priority so the app will process large datasets fast while keeping the interface simple and intuitive. Deliverables include the compiled Windows executable, full source code, the GUI with all filters, and a short user guide. I’ve previously built similar betting analytics tools involving league filters, odds tracking, and fast recalculation for strategy testing. Best regards, Joseph

As a Full-Stack Developer, I bring an ideal combination of technical proficiency, efficiency and commitment to your table. Your sports-betting app requirements align perfectly with my deep interest in data processing and visualization. My extensive experience in working with large data sets and using filters to extract specific information will certainly come handy for you. I assure you quick and smooth import of your Excel spreadsheets using scripts I can create specifically for their format. Incorporating the odds provided from your Pinnacle-API source also won't be an issue for me. In terms of technology stack, I believe C#/WPF would be the perfect fit maximizing the performance on a Windows system without any extra overhead. Creating a responsive GUI that allows filters to be adjusted while instantly updating the result tables and charts for on-the-fly result analysis would be one of my forte. I have already delivered several projects requiring real-time filtering while maintaining high-performance. Lastly, as someone who prides himself on delivering accurate results while being user-focused, I acknowledge and assure the important metrics you've listed – such as yield, ROI, max drawdown (plus total profit, hit rate, stake turnover if easily added) will be there with utmost precision — justifying both the time spent by you on this back-testing as well as my selection for this project.

@mattafareed4848

Hello I can build a Windows desktop back-tester with a clean GUI (C#/WPF or Python+PyQt) that imports your Excel/CSV files and Pinnacle JSON (converted to Excel), provides real-time filtering by sport/league/team/odds ranges/odds movement, refreshes tables & charts instantly, lets you save/load filter “Strategies”, and includes per-run performance metrics (yield, ROI, P/L, max drawdown, hit rate, stake turnover). I’ll supply import scripts for each source (including the two files that need pre-processing), robust handling for 100k+ rows with responsive UI, a compiled executable plus full source, and a short user guide; I’ll also validate metrics against your sample calculations during acceptance.
