It is posible for some reasons.
- It is a demo account contest normaly. So in demo the trading condition is different than real:
- No pressure
- Spread is smaller
- Execution is instant
- Some will try to cheat, you know there are guys willing to create hundress of email and sell them for 1$ each. So if a contest is 3000$ rewards, there would be many of them. There are many ways to cheat:
- Have 100 accounts, 50 buy , 50 sell 10 lots, wait for a day until 50 account got margin call. Now you have 50 accounts with maybe x200%. Now devide by 25 accounts sell and 25 accounts buy 10 lots. Continues until you have 1 account of supper supper crazy..
- Just try any systems anf goal all in for it.
Anyway all kind of cheat just waste of time.
