"In play" is day-trader shorthand for the names everyone is watching today: something has happened, volume is pouring in and the price is moving. This screen lists stocks on Asian exchanges up or down more than 3% today on at least twice their 21-day average volume, with an average true range above 3% of the price, so there is room to trade. The heaviest relative volume comes first. Prices are in each exchange's local currency, and the list covers stocks traded in Tokyo, Hong Kong, Singapore, Seoul and Jakarta with at least about US$0.7 million in average daily trading value.
