Understanding the pair
In USD/MXN the US Dollar is the base currency and the Mexican Peso is the quote currency. The rate tells you how many MXN one USD buys, so a rising USD/MXN means the US Dollar is strengthening against the Mexican Peso.
USD/MXN is an exotic pair: it combines a major currency with that of a smaller or emerging economy, so spreads, swap costs and the size of sudden moves are typically larger than for the majors.
Prices are quoted to 4 decimal places here. One pip is 0.0001, so on a standard lot of 100,000 USD a one-pip move is worth 10 MXN — use the pip calculator to convert that into your account currency.
Both currencies are most actively traded during the New York (08:00–17:00 New York time) session. See live session times on the market hours clock.
The world's main reserve and invoicing currency. The BIS 2022 Triennial Survey found the dollar on one side of about 88% of all FX trades, so US interest-rate expectations and risk sentiment ripple through almost every pair.

USD/MXN shows how many Mexican Peso (MXN) one US Dollar (USD) buys. USD is the base currency and MXN is the quote currency. If the rate rises, the US Dollar has strengthened against the Mexican Peso.
No. It is derived from the euro foreign exchange reference rates published by the European Central Bank once per working day around 16:00 CET. It is useful for reference, budgeting and calculator inputs, but it is not an executable trading quote — a broker's bid and ask will differ.
By convention one pip in USD/MXN is 0.0001 because the pair is quoted in MXN. On a standard lot of 100,000 USD, a one-pip move is worth 10 MXN. Brokers may quote an extra decimal (a pipette).
Both currencies have their home market in the New York (08:00–17:00 New York time) session, so liquidity is typically deepest then. The pair still trades around the clock from Sunday evening to Friday evening (New York time).
