When traders start building systematic strategies on index futures, the first question is usually which market to start with. E-mini S&P? NASDAQ? Dow Jones? DAX? Nikkei?
Tomas’s answer might surprise you: he doesn’t have a preference. Whatever fits well into the portfolio and is robust enough — that’s what gets traded. It’s a portfolio-first mindset, not a market-first one.
Watch the clip below, then read on for the full breakdown.
Why Market Preference Is the Wrong Starting Point
Most traders start by picking a market they find interesting or have heard a lot about, then try to build strategies on it. That’s a natural instinct — but it’s backwards.
The right question isn’t “which market do I want to trade?” It’s “which markets produce robust strategies that aren’t correlated to what I’m already trading?” The market that fits that description is the one that belongs in your portfolio, regardless of whether it’s your favourite or not.
This mindset shift — from market selection to portfolio construction — is one of the things that separates systematic traders who build durable portfolios from those who keep cycling through individual strategies without ever developing real diversification.
The Main Index Futures Markets
Here’s a practical overview of the key index futures worth considering for breakout strategies:
E-mini S&P 500 (ES) — The most liquid futures market in the world. Deep order books, tight spreads, and consistent behaviour across both day and swing trading time frames. The default starting point for most systematic index traders. Requires meaningful capital due to contract size (though Micro E-mini S&P — MES — provides a smaller alternative).
E-mini NASDAQ 100 (NQ) — Higher volatility than ES, which means larger moves but also larger drawdowns. Strong breakout tendencies, particularly on trend days. Works well for both day and swing strategies, though position sizing needs to account for the higher volatility. Micro version (MNQ) available.
E-mini Dow Jones (YM) — Often overlooked but worth including. Lower volatility than NQ, behaves slightly differently to ES, and can provide genuine portfolio diversification when combined with S&P and NASDAQ strategies.
DAX Futures (FDAX / FDXM) — The European index flagship. Excellent liquidity, strong trending behaviour, and importantly — it trades on European hours, which means low correlation to US session index strategies. The Micro DAX (FDXM) reduces the capital requirement significantly.
Nikkei 225 (NKD/NK) — Japanese equity index. Trades during Asian hours, providing genuine session diversification. More volatile and less liquid than the major US contracts, but can complement a US and European index portfolio effectively.
Robustness Over Popularity
The mistake is chasing the markets everyone talks about. NASDAQ gets a lot of attention because of its volatility and the spectacular moves it can produce. But high volatility cuts both ways — strategies on NQ tend to have larger drawdowns, and the high-profile nature of the market means more traders are trying to exploit the same patterns.
The DAX and Nikkei get far less attention in the algorithmic trading community, which is partly why they can still offer genuine opportunity. Less competition, less arbitrage, more persistent inefficiencies for systematic breakout strategies to exploit.
The practical test is always: does this market produce strategies that are robust across different parameter sets, different time periods, and different market regimes? If yes, it belongs in the consideration set. If no, the market’s popularity is irrelevant.
Starting Small: The Micro Contracts
One of the most useful developments in index futures over the last several years is the introduction of Micro contracts — one-tenth the size of the standard E-mini contracts. Micro E-mini S&P (MES), Micro NASDAQ (MNQ), Micro Dow (MYM), and Micro DAX (FDXM) all allow you to trade with significantly less capital while still getting real market exposure.
For strategy development and live testing, the Micro contracts are invaluable. You can run a strategy live, observe real execution behaviour, and build track record data without the full capital commitment of standard contracts. Once a strategy proves itself live, scaling up to the standard contract is straightforward.
Building a Multi-Index Portfolio
The ideal systematic index portfolio spans multiple markets and multiple time frames. US indices, European indices, and Asian indices behave differently enough — and trade on different schedules — that a well-constructed multi-index portfolio can be running productive strategies around the clock.
Start with one or two markets, build 2-3 robust strategies on each, validate them properly, then expand. Adding markets without validated strategies is just adding complexity and risk.
