MarketParquet vs Norgate Data
> survivorship-bias-free end-of-day data for systematic traders
Norgate Data is the go-to end-of-day source for systematic traders on AmiBroker and RealTest, famous for survivorship-bias-free history with point-in-time index constituents -- but it's daily-only, Windows-updater-based, and subscription-priced. MarketParquet adds 1-minute intraday bars, ships open Parquet for any OS, and is a one-time fee. Here's the honest comparison.

| Access | Windows updater app + AmiBroker/RealTest/Python plugins | Apache Parquet files -- any OS, pandas/polars/duckdb |
| Intraday / tick | no -- end-of-day only | 1-minute intraday (no tick) |
| Survivorship bias | yes -- delisted + point-in-time index constituents | yes -- delisted tickers included |
| Pricing | subscription ~$270-$788/yr (US stocks) | one-time $79 |

Where MarketParquet wins
- Intraday resolution: 1-minute to daily bars, vs Norgate's end-of-day-only data.
- Open Parquet files usable on macOS, Linux, or Windows in any language -- no Windows-only desktop updater.

Which to pick
Pick Norgate Data if you do end-of-day systematic trading in AmiBroker or RealTest and want point-in-time index constituents, decades of daily history, and Australian/Canadian markets.
Pick MarketParquet if you need intraday (1-minute) bars, want open Parquet files on Mac/Linux, or prefer a one-time price over an annual subscription.
FAQ
Is MarketParquet a Norgate Data alternative?
Partly. Both give you survivorship-bias-free US equity history at a low price. Norgate is end-of-day only, Windows-updater-based, and subscription-priced (~$270-$790/year), with point-in-time index constituents and history back to 1950. MarketParquet adds 1-minute intraday bars, ships open Parquet for any OS, and is a one-time $79 -- but it's US-only and doesn't offer historical index membership.
Does Norgate Data offer intraday or Parquet data?
No -- Norgate is end-of-day (daily) only, delivered through a Windows desktop updater and plugins for AmiBroker, RealTest, and Python. MarketParquet provides 1-minute-to-daily bars as Parquet files you can load on any OS with pandas, Polars, or DuckDB.
Is Norgate Data survivorship-bias-free?
Yes -- it's their headline feature: Platinum and above include delisted stocks plus point-in-time index constituents for accurate index-membership backtests. MarketParquet also includes delisted tickers so the price panel isn't survivorship-biased, though it doesn't provide historical index-constituent membership.
Does Norgate Data work on Mac or Linux?
Not natively -- the Norgate Data Updater is Windows-only, so Mac/Linux users run it in a VM or VPS. MarketParquet is just Parquet files, so it works directly on macOS, Linux, and Windows in any language.
