Open trading account 
I find this contest exciting and engaging but it seems to me that the amount one starts the contest with at the beginning of the week needs to be factored into the calculation of the profitability percentage. Here is what I have observed. The smaller the amount one starts the contest with, the better their chances of winning by a greater percentage. In other words, one who starts the contest on $1 has a better and quicker chance of getting to 100% by just adding another $1 to the starting amount, than one who starts the contest with $100. The practical implication of all this is that at the end of the week one is better off quickly reducing the trading amount in their account to the lowest amount possible to increase their chances of winning. It would seem fairer that one who starts the contest trading $1000 should have the same chance of posting a winning profitability percentage as the one who starts the contest with $100. Now, I am not a mathematician so I have no idea how this aspect could be factored into the calculation of the profitability percentage, but I am sure the Dukascopy team can figure a way out. Otherwise a simpler solution would be that we all start the contest from a fixed amount.
I apologise if this point has been raised by others in earlier posts and I missed it. But even If that is the case, I still feel this is an aspect that merits further consideration.
