A few months ago, when PPX was but a wobbly infant, we tried out the idea of a one-percent commission on all trades, with the idea that this would keep the market more fair and accurate. Unfortunately, since there were only a few thousand traders at the time, the exchange came grinding to a halt, and we responded by removing the commission to encourage a fun environment with a high trade volume.

But now that PPX is more mature, with a community of over 16,000 members, we're ready to try the experiment again— in a new, carefully considered fashion. This time around, rather than charging a percentage of the trade value, PPX will charge a flat POP$0.25 per share for each trade. The commission will be instated at 3 pm EDT, tomorrow: Friday, September 28th. Our hope is that this policy will increase the accuracy of the predictions generated.

Due to some unexpected complications, we have temporarily removed the recently implemented 1% commission on PPX trades. We're working on developing a system that simultaneously satisfies the needs of our traders and the integrity of the market's prediction data. Many have come forth with ideas in the PPX forums—thanks to all there for the input. We'll keep you posted of any more developments right here.

Until then, happy (commission-free) trading!
