How far back does USD/RON data go?

USD/RON history runs from 2016-12-19 — roughly 10 years — up to the last completed trading day, at every timeframe from raw ticks to monthly candles. Every licence tier reaches all of it.

How large is a full USD/RON download?

The complete USD/RON 1-minute history is roughly 3.5M rows, about 174 MB as CSV. Daily candles over the same instrument are far smaller — around 2,400 rows, 121 KB. Tick and 1-second runs are larger again and are queued and resumable rather than fetched in one pass. Sizes are approximate; nothing is priced by volume.

What columns are in the USD/RON CSV file?

OHLC files contain a timestamp plus open, high, low and close columns (with volume); tick files contain a timestamp with bid and ask prices. All timestamps are UTC. The files import directly into Excel, Google Sheets, Python (pandas read_csv), R, MetaTrader, NinjaTrader and TradingView.

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 2026-08-01:

Timeframe	History from	Approx. rows	Approx. CSV
Tick (every quote)	2016-12-19	very large	—

Counts are approximate, derived from forex session hours across the available history. Tick and 1-second runs are queued and resumable rather than fetched in one pass. See the data methodology for how candles are built.

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.
