EA will trade the Nasdaq100 exclusive. Intraday trades only, all open positions will be closed 5 minutes before US trading ends. The 1st daily trade will be placed at the start of trading in Germany (postponements due to changeover to Sun/Wi times). There are usually no open positions at night and on weekends.

Goal is an average profit of 10% per month. The EA can definitely have short negative phases. But he always delivered.

A leverage of at least 1/100 should be possible for copying.
At US$1 per point per lot, the capital should be at least US$7500.
With 0.10 US$ per point per 0.1 lot possible, at least 750 US$ is enough.
At MicroLot and 1 cent per point, at least US$ 75 is enough.

If, for example, the Nasdaq Future is used at ActivTrades, which makes 0.2 US$ per point for 0.01 lot, you need 1500 US$
I have been trading the Nasdaq Cash Index (UsaTec) since October 16, 2023. This makes 0.2 US$ per point for 0.2 lots (1US$ per point/lot)
The spread here, at an average of around 1.2 points, is significantly lower than that of the Nasdaq Future, which recently had an average spread of around 2.5 points. The lower spread allows performance to be increased significantly.

It is possible to start with less capital then the possible drawdown and risk increases.
