Both Forex.com (retail) and GTX (institutional) saw rising volumes in August, though still below Jan-Jun metrics.

After seeing August volumes drop by 20%, US forex broker Gain Capital did see some improvement in September, as overall forex trading volumes rose 4% to $409 billion — $130 billion at Forex.com and $279 billion at Gain GTX. However Gain’s volumes in September lagged well behind the $475 billion average monthly volumes the company saw in the first six months of the year, clearly evident from the chart below.

Gain’s September results included seven days worth of volumes from GFT — Gain closed its acquisition of GFT on September 24. Thus, most of the (modest) rise in volumes Gain saw in September were courtesy of the added GFT volumes. Without GFT, Gain’s September would likely have been slower than August.

Gain Capital has seen a nice rise in its share price this year. Gain shares (NYSE:GCAP) have nearly tripled in 2013 year to date, now at $12.25.
