Guys, to answer your questions:
1. Hedging is indeed allowed (checked in the FXDD Malta MetaTrader 4).
2. Leverage is unlimited.
3. No MM restrictions.
4. No manual/automatic trading restrictions.
5. Prizes transferable to charities - once you withdraw the prize money, you can do whatever you want 😄
In general, there are no restrictions as we wanted to open the contest for everyone.
You can trade manually or even use your best EA without giving away your EA. Basically, anything goes 😄
