How sizing works on the DAX

GER40 — DE40, GER30 at older brokers, or simply DAX — is a CFD on Germany's DAX 40 index, and it is priced in euros. The calculator assumes 1 per point: one lot gains or loses €1 for each index point, 0.01 lot €0.01. On a euro account that is the whole calculation. On a USD, GBP or other account the euro loss is converted to your currency, so the value of a point shifts a little every day with the euro. Type the rate (for a USD account, the EURUSD price), or the calculator uses the reference rate of 1.1401 from 27 September 2026 and labels the result an estimate.

A worked example: USD account and euro account

A $10,000 USD account risking 1% has $100 to lose. With a 30-point stop and no rate typed, one point per lot is €1 × 1.1401 = $1.1401, so one lot loses 30 × 1.1401 = $34.20. The raw size is 100 ÷ 34.203 = 2.924, rounded down to 2.92 lots, and the actual risk is $99.87 — marked as an estimate until you type today's rate.

The same trade on a €10,000 euro account: risk €100, one lot loses 30 × €1 = €30, the raw size is 3.333 and the position 3.33 lots, risking €99.90. The DAX contract varies by broker, so check yours in the symbol specification. At €25 per point, set the contract size to 25: one lot then loses €750 on the same stop and the size is 0.13 lots, risking €97.50.

DAX volatility and typical stops

At around 24,300 a 1% move in the DAX is about 243 points. Intraday stops of 20 to 50 points are common for setups around the open. The first minutes after 09:00 Frankfurt time, when Xetra opens and the index is calculated from live share prices again, often bring the widest candles; German and euro-area data, ECB decisions and the US open at 15:30 Frankfurt time do the same later.

Frankfurt hours in New York time

Frankfurt is six hours ahead of New York for most of the year, and five during the few weeks when one side has changed its clocks and the other has not. The Xetra open at 09:00 Frankfurt is therefore 03:00 New York time — inside the London Kill Zone, 02:00–05:00 — and the 17:30 close is 11:30 New York, after the New York AM Kill Zone of 07:00–10:00.

Common DAX sizing mistakes

• Treating a euro point as a dollar point. On a USD account €1 is about $1.14 at the reference rate; ignoring that risks 14% more than planned.
• Typing the rate the wrong way round. The field wants how many units of your account currency one euro buys: about 1.14 for a USD account, not 0.88.
• Mixing up GER30 and GER40 symbols. They are the same market, but an old and a new symbol at one broker can have different contract sizes — check each symbol's specification.
• Sizing a tight stop before the Xetra open without adding the wider pre-open spread to its distance.
