Services
Six focused services built around one goal: research you can trust and verify.
Historical Market Data
Cleaned end-of-day and intraday price data for U.S. equities, ETFs, futures and major FX pairs, adjusted for splits and dividends and delivered as CSV or Parquet.
Custom Backtesting Reports
Send us your rules in plain English, a spreadsheet or code. We rebuild the strategy, run it on clean data and return a full written report.
Strategy Code Review
We audit Python, Pine Script, MQL or EasyLanguage backtests for look-ahead bias, survivorship bias and unrealistic fills.
Walk-Forward & Monte Carlo
Out-of-sample testing, parameter stability maps and thousands of resampled runs to show how fragile — or robust — a result really is.
Data Cleaning & Validation
Already have data? We find gaps, bad ticks, duplicate bars and timezone errors, then document every fix we make.
Education & Workshops
Small-group sessions for trading clubs, colleges and educators on how to design honest, repeatable research.

Clear boundaries
We don’t manage money, sell signals, recommend securities, or tell you what to buy. We don’t sell “guaranteed” strategies — nobody honest can.
Our job is narrow: give you accurate data and an unbiased view of how a set of rules behaved historically. Your decisions remain yours.
Important: Backtested results are hypothetical and are prepared with the benefit of hindsight. They do not represent actual trading and do not guarantee future performance. DataBacktest does not provide investment advice. See our Risk Disclaimer.
