To gamble or not to gamble?

There is only two more trading days left in the April Dukascopy JForex Strategy Contest. I am currently ranked 6th. But there's a fierce fight for my spot. I've been moving between 6th and 8th all week even though I haven't made any trade. The other people are putting on big bets hoping to squeeze in a top 6. Why? According to the winning prize structure, the 4th to 6th winners will each receive \$1,000. Whereas the 7th to 10th will each receive \$500 only. With my current account standing at \$120,032 (20% gain) this month, it is quite viable for others to try to take my spot. See the table below for the top 10 standings as of this writing.

My options are to either fire up my strategy to make more trades or do nothing. The risk in running my strategy again is that I might lose money and make myself even less competitive. My strategy's working timeframe is in hours, so there isn't much room for error. As such, I feel that with only two days of trading left, time is not on my side.

On the other hand, I will probably lose out my 6th spot as I am not far away from others behind me. So if I do nothing, I will most likely end up 7th or 8th and lose half the prize money.

After pondering about this briefly, I've decided to do nothing. The odds are just too much against me. I have seen too many people in this month's contest risking to move up from a good rank only to expose themselves too much and lose out of the top 10 completely.
