without live account ,when Prize will be Remove From Community?
There's no expiration date attached to prizes won in Dukascopy Contests - let's hope it stays this way.
However, rule 2. under "Other rules and policies" in Dukascopy Contests rules, states:
"Dukascopy reserves the right to disqualify a Participant, to change the Contest rules, requirements and awards, without prior notice and at any time and at its sole discretion."
Therefore, a prudent approach would be to open a live account, transfer the prize and complete turnover requirement as soon as you can.
