Hi Ealge
right now the FDAX is at 9842 points. The regular FDAX contract has a point value of 25 EUR, so the notional value of the FDAX is 9842 x 25 EUR = 246,050 EUR.
This value basically shows you how much capital you control/ move with one FDAX contract. As you can see the value of the FDAX is pretty high, compared to other index futures. This means you control lots of capital. Also, the FDAX is a very volatile contract. These days we have intraday ranges of at least 100-200 points, which means that with just one FDAX contract your risk capital might fluctuate about 2500 to 5000 EUR per session if you just hold from session opening to close. Lots of movement means lots of chance for profits, but also high risk for losses.
Because of this risk, the margin for the FDAX is pretty high. The initial margin set by Eurex today for the FDAX is 18,482.50.

Interactive Brokers wants at least this initial margin on your account for each FDAX contract you trade, to have the insurance that you are able to cover potential losses.

For daytrading, Interactive Brokers will usually ask for just half of the initial margin, so in case of the FDAX you would need then about 9200 EUR in your account.
For the new miniDAX contract it is very similar, the main difference is that it moves in full points and not in half points like the large FDAX. And each point in the miniDAX is only 5 EUR, so only 1/5 of the large contract.
If you want to trade a smaller contract that moves almost 1:1 with the DAX you might also try the FESX, the EuroStoxx50 Futures. These 2 contracts are highly correlated and you can monitor the FDAX and execute on the FESX, as long as you dont want to do VERY shortterm scalping. Then other factors might come into play.
Hope this helps a bit.
