Built for the job before the backtest
The expensive work is not only getting price files. It is making the files loadable, consistent, and inspectable enough that a research result is worth reading.
Load M1 OHLCV data into pandas, DuckDB, R, or a local research database.
Validate timestamp coverage before trusting strategy-test results.
Avoid rebuilding the download, normalization, Parquet conversion, and QA pipeline from scratch.

Recommended workflow
This is the path that gets a buyer from curiosity to a real paid result without pretending every trading platform wants the same file format.
2. Buy the smallest useful bundle
Use the major-pair bundle first if your strategy depends on liquid FX pairs and you want the fastest path to a real test.
3. Check release coverage
Use the included coverage reports to see what is source-backed, what is current, and where known gaps still exist.
4. Run your own tests
Load the files locally and run your backtest without API quotas, broker platform limits, or hidden data-fetch steps.

Backtesting data questions
Is this tick data or M1 data?+
The current sellable product is M1 OHLCV historical forex data in Parquet format. Tick-level delivery is not positioned as live until matching source files, QA, and fulfillment artifacts exist.
Can I use this for MT4 or MT5 backtesting?+
The live paid artifact is Parquet. You can convert it for your own MetaTrader workflow, but broker-native MT4 or MT5 files are only sold after separate conversion QA passes.
Are gaps filled with synthetic prices?+
No. Known missing intervals are not patched with fake continuity. Releases are packaged from observed source data and shipped with coverage reporting.
What should I buy first?+
Start with the free sample. If the format works, the major-pair bundle is the practical first paid download for most strategy research workflows.
