I am a newbie to this market.
Let's take the example of Edward Snowden to be awarded the 2014 Nobel Peace Prize
If I short sell it for 0.10 m฿, it means that I win 9,90 m฿ if it doesn't happen?
You want to sell "
Edward Snowden to be awarded the 2014 Nobel Peace Prize" meaning you think this will not happen. If your prediction is correct (i.e he doesn't win the Nobel Peace Prize), you will win the price for which you sold the shares, so in your example 0.1m฿ for each (short) share you own. If you lose, you would lose (10m฿ - 0.1m฿) = 9.9m฿ per share.
So basically, if you buy a contract, you will win 10mB for each share of this contract you own (if you’re correct). On the opposite, if you sell a contract (because you think an event will not occur), you win the price you sell for.
Note that in Predictious you can set your own odds. Of course if you set a selling price per share too high (high return for you), there might be a risk that noone matches your bet (your open order won’t be matched and you won’t own any share). If you click on the Market depth tab, you can see the available ask/bid price (for example someone is selling 3 shares at 2.65mB; 10 shares at 2.85mB, etc.).
