The fundamental items weren't showing the buy and sell prices. Now using last price rather than the now obsolete medium price to calculate buy and sell prices. Low volatility items have a lower spread than standard and this is automatically calculated.
The Sqlite database is still occasionally corrupting. This is not a fault with Merchstation but something to do with the database provider, so I am trying to find a solution to the issue. If the database corrupts then Merchstation has to drop the item and item history tables and recreate them. After it recreates the tables Merchstation synchronizes with the server and you can start searching for results straight away but after a few minutes more results will be available.
