Using an intuitive visual format, the sentiment indicator provides an additional source of information to help players when making predictions. It shows whether all users of the system are buyers or sellers of each instrument, in aggregate. Spark Profit players who make accurate predictions collect points that convert to cash prizes.

To activate the free sentiment indicator, users will need to make 15 predictions of their own. Uniquely, historical data is also shown, to help players learn when to follow the crowd - and when to lead it.

There are currently 29,000 Spark Profit users in 194 different countries, with around 3,000 additional users signing up each month.

Spark Profit can be accessed via www.sparkprofit.com or downloaded from iTunes or Google Play.

Many Spark Profit players started out with no previous trading experience, but the best have developed original strategies that consistently outcompete their peers and outperform the markets.

Nous intends to monetize Spark Profit's price prediction data by integrating it into a range of professional data feed products it will sell to hedge funds, banks and other financial institutions. A pilot international hedge fund is trialing feeds that Nous launched in February.

Justin Short, CEO of Nous, says:

"The purpose of our new free sentiment indicator is to help market participants improve their trading strategies by showing them the average person's viewpoint, from right now all the way back to Spark Profit's launch in January. This tool also hints at the powerful insights available in our Spark Data products - the suite of feeds we supply to professional traders.

"In launching the global sentiment indicator we have been at pains to design a system that provides exclusive, actionable information without creating a systemic bias for our players. We hope existing and new users will use it to boost their returns."
