The GER40 (also known as the DAX 40) is one of the most popular indices among European day traders and prop firm traders: plenty of movement, clear sessions and wide availability at nearly every firm. But that same movement makes it treacherous. Without a journal you can't tell whether your GER40 profit comes from your strategy or from luck.

Why GER40 is popular with prop firm traders

Journal per session: the most important difference

A GER40 trader who trades 'in the morning' is in practice doing several different things: the open, the midday consolidation and the US opening volatility each behave differently. If you lump everything into one set of statistics, a good session hides a bad one.

  1. Tag every trade with its session: European open, midday or US overlap
  2. Note whether the trade happened before or after a major news event
  3. After 30 trades, compare your win rate, average R:R and discipline score per session
  4. Drop or limit the session in which you structurally break rules, even if it is sometimes profitable
Why 'sometimes profitable' is a trap

A session that occasionally produces a big winner but often makes you break rules feels good and costs you the account over time. Your journal shows whether your profit is reproducible or accidental. Only reproducible profit is an edge.

Risk management on the GER40

Because the GER40 can move fast, position size matters more here than on calmer markets. Sizing from your stop loss distance in points, rather than from a fixed number of lots, prevents one wide stop from hitting your daily limit.

Tracking GER40 setups in your journal

If you trade Smart Money Concepts, it helps to tag not just 'GER40' but also the setup type: for example a liquidity sweep followed by a CHoCH and a Fair Value Gap entry on the 5-minute. That shows you which variant works for you and which to leave alone.

More on the underlying concepts in what is a liquidity sweep and what is a Fair Value Gap.
