IPC Mexico Index (MEX35) Trading Guide 2024

The MEX35 has a pip size of 1 and a pip value of 1, meaning every single point of price movement equals exactly $1 per contract. That sounds modest — but at a typical spread of 50 pips, you're starting each trade 50 points in the hole before the market moves a tick in your favor. Compare that to the DAX40, which often trades with a spread of 1-2 pips, and you immediately understand why position sizing on MEX35 demands a different mindset.

The contract size is 1, which keeps things clean mathematically. If you open 2 lots and the index moves 100 points in your direction, you profit $200. Reverse the move and you lose $200. No complex multipliers to account for.

The IPC (Índice de Precios y Cotizaciones) was established in 1978 and has grown to represent sectors including financials, consumer staples, telecommunications, and mining — with América Móvil and Grupo Financiero Banorte historically among the heaviest weightings. Because the index reflects a commodity-linked emerging market economy, it tends to show elevated sensitivity to oil price swings, US dollar strength, and Federal Reserve policy decisions. A 25-basis-point Fed rate hike can move MEX35 by several hundred points within a session, purely through the USD/MXN transmission mechanism.

Why this matters: knowing that MEX35 is a spread-heavy instrument tied to emerging market risk appetite tells you immediately that scalping is expensive here, and that macro events carry outsized weight compared to purely technical setups.

MEX35 trades from 01:00 UTC Monday through 22:00 UTC Friday, divided into three distinct windows: Pre-Market (01:00–14:30 UTC), Regular (14:30–21:00 UTC), and Extended (21:00–22:00 UTC).

The Regular session — 14:30 to 21:00 UTC — is where you want to be. This window aligns directly with the opening of the Bolsa Mexicana de Valores and overlaps with the US equity session from 14:30 UTC onward. That dual overlap creates the highest volume, tightest effective spreads relative to the quoted 50-pip norm, and the most reliable follow-through on breakouts. Major Mexican economic releases, including Banxico monetary policy decisions and GDP prints, are typically scheduled within this window.

The Pre-Market phase (01:00–14:30 UTC) sees thin participation. Price can drift or gap on overnight news — particularly anything touching US-Mexico trade relations or Pemex (the state oil company, which influences sentiment on the index). Positions held through Pre-Market are exposed to gap risk without the liquidity to exit cleanly.

The Extended session (21:00–22:00 UTC) is a 60-minute tail that catches late US session momentum. Volume drops sharply here. Spreads effectively widen in real terms because market makers pull depth. Unless you have a specific reason to hold into this window — such as managing an open swing trade — most intraday strategies should be closed before 21:00 UTC.

A counterintuitive reality: the first 30 minutes of the Regular session (14:30–15:00 UTC) are often the most volatile but not necessarily the most tradeable. Order flow is chaotic as institutional players rebalance. Waiting until 15:15 UTC for the initial volatility to settle frequently produces cleaner entry signals with better risk-to-reward ratios.

The 50-pip spread on MEX35 is not a minor detail — it is the central risk management problem for this instrument. Any stop-loss placed less than 50 points from entry is almost certain to be triggered by normal bid-ask fluctuation before the market has had a chance to move in your direction. Treat 50 pips as the absolute minimum buffer just to escape the spread, and build your stop placement from there.

A practical rule: for intraday trades during the Regular session, stop-losses below 100 points are generally too tight. The index can swing 150–300 points on a single US macro release without any change in the underlying trend. A 150-point stop with a 300-point target gives you a 1:2 risk-to-reward ratio — the minimum worth accepting on a spread-heavy instrument.

Position sizing follows directly from pip value. If your account risk per trade is $200 and you're placing a 200-point stop, you can trade exactly 1 lot (200 points × $1 per pip × 1 lot = $200 risk). Scale up to 2 lots and your risk doubles to $400. The math is refreshingly simple given the pip value of 1, but that simplicity can lull traders into oversizing.

Correlation risk deserves attention. MEX35 has a historically positive correlation with crude oil prices (Mexico is a significant oil exporter) and a negative correlation with USD/MXN strength. Running a long MEX35 position alongside a long crude oil trade is not diversification — it is concentration. Stress-testing your portfolio for scenarios where oil drops sharply and the peso weakens simultaneously is a necessary discipline for anyone holding MEX35 overnight.

For swing trades held across multiple days, the Pre-Market gap risk described earlier becomes a direct risk management concern. Sizing swing positions at 50% of your normal intraday size is a reasonable adjustment when you cannot monitor the market during the 01:00–14:30 UTC window.
