USD/RON Historical Data Downloader
A desktop app that downloads US Dollar vs Romanian Leu (USD/RON) price history on your own machine, written straight to your disk as CSV or JSON. History runs from 2016-12-19 — around 10 years — at every timeframe from raw ticks to monthly candles. A complete USD/RON 1-minute series is roughly 3.6M rows, about 179 MB as CSV.
Or work out the size first: the file-size calculator takes a range and returns the row count and CSV size.

USD/RON coverage & file size, timeframe by timeframe
Every USD/RON timeframe shares the same 2016-12-19 start date, but not the same scale — coarser candles stay small while tick and intraday files grow fast. Current through 2026-11-02:

Working with the USD/RON series
The leu is a managed float in practice: the National Bank of Romania smooths the EUR/RON rate so effectively that its volatility is a fraction of free-floating regional peers, and USD/RON is largely EUR/USD wearing that smoothing. Long flat stretches punctuated by small step-adjustments are policy fingerprints, not market microstructure. Models premised on continuous price discovery will misread them.
What's inside the USD/RON file
timestamp,open,high,low,close,volumeOne row per candle, stamped with the bar's opening time; tick files instead carry timestamp,askPrice,bidPrice,askVolume,bidVolume on every quote — ask first. Timestamps are epoch milliseconds in UTC, which pd.to_datetime(df.timestamp, unit="ms", utc=True) or =A2/86400000+DATE(1970,1,1) turns into a date. Worked examples and import steps are in the CSV & JSON format guide.
