I am updating this to directly answer your question. Let’s say you won 1st place $6000 in trader contest.
You had your strategies run on the live account for a couple of months turning over 300 million USD and taking your initial deposit of $6,000 to $12,000.
In this scenario, you have already paid Dukascopy it’s ‘dues’ in commissions (turnover requirements) and you now have a live account of 12,000 that you own 100%.
At this point you can choose to close and transfer the entire amount to your bank or continue trading. However, should you win another $6000 in the contests, I believe you will have to meet the withdraw requirements gain.
To see the color of money, first you win the championship, then wins the battle to move all this money to be able to withdraw the money you supposedly prize gain. Honestly do not know what is more difficult, if it is to win the competition or move 2.5M for each $ 100 prize gains without losing any money.
