First of all, am not a big fan of trading contest because you will act and be taking trades you shouldn't have because you are desperate, but if you are not in any pressure to trade, you might take a single trade in a whole week and even make more than those that trades constantly every day throughout the week because all those traders they took will be unsuccessful traders due to pressure of trading because others are already making it, so my advice to you is that their is no need getting into a trading contest because you might even liquidate your margin in the process due to constant taking trades that is not worth it.
Furthermore, the best way  to make money in the market is to trade less, because you will only be trading a set up that is 100% certain, but if you get into a trading competition, you have practically removed that patience you once have because you will be desperate in your actions.
