A European equity trading platform founded by industry veteran Alasdair Haynes is set to double its membership base by the end of 2016 after making a radical change to its model in February.

Aquis Exchange, which started trading in November 2013, has secured the commitment of 17 firms to become members by the end of the year, according to Haynes. This would take the platform's total membership from 16 to over 30.
