New Report Features

Today we made some updates to the ‘All Trades’ and the ‘Price Changes’ reports which site administrators can begin using right away. Here is a list of the changes:

All Trades Report:

   added: stock status
   added: market status

Price Changes Report:

   added: price status
   added: stock status
   added: market status
   added: market type
   added: price id

The ‘All Trades’ report now has two new columns: stock status and market status. The ‘stock status’ column will show you the current status of the stock (also known as your possible answer) for every trade. When an answer is resolved, it will flag all trades for that market in the report as either ‘closed’ or ‘open’ depending on whether or not the question has resolved.This may be different than the status of the market (the question you’re asking) in the case where multiple answers may be correct, or if the possible answers are independent of each other (for example, in the question “What will the closing price be on these days in 2013 for Google?”, the stock for the answer last day in March (0LDIM) may cease trading at the end of march, while June, September and December stocks continue active trading).

The ‘market status’ column, similarly, will tell you the status of the market (also known as your question). We had users coming to us requesting these new columns so they could better understand what was happening with trading in their active markets or when they needed to run historical analyses only on their closed markets.

We also added five new columns to the ‘Price Changes’ report. The price changes report shows every prediction on a site and is often used to answer time series questions about Inkling data. The new columns are: price status, stock status, market status, market type, and price id. The price status column, tells you how the price was generated in the market. When you create a new market an initial price is set by the user who generates the question. This is the question originator’s prediction and will be flagged with a status of ‘initial’. This status may be useful if you do not wish to include the starting price in your analysis. A status of ‘market’ indicates that the price was derived via a trade in an active market and a price status of ‘final’ tells you the price set when the answer (stock) was resolved. Final prices are set to either 100 or 0 and are often removed when analyzing price movements. A status of ‘final: no trades’ is set when the answer was resolved without any trading having occurred for that stock.

Because different market types have very different characteristics, as a site administrator you may want to perform your analysis on only certain kinds of markets. The market status column will give you what type of market the prediction occurred in. For most of Inkling’s markets, this will be one of the following: Binary (yes or no answer), a DateMarket (what specific day will something happen), a DateRange (between what range of days will an event occur), Futures (the answer is a number), or Options (multiple choice).

Finally, we added the price id to give you a unique identifier for every prediction on your site, this is typically useful when you are doing analysis where you need to drill down on a single prediction or join data sets together relationally.

These changes lay some of the groundwork for some exciting features on the horizon in our graphing and reporting capabilities. Check back often to see what we’re doing to try to make Inkling’s data more accessible and insightful.
