Online dealing is expected to triple again in the next six months, APCIMS said.
'The internet is really starting to take hold for the investor who is looking for a simple execution-only deal. The online investor at this stage appears to be somebody who trades in little amounts, but trades often,' Angela Knight, chief executive of APCIMS said.
There are now about 38,300 online share-dealing accounts, each of which makes about 12 trades per year.
The average online trade is for £4,549 worth of shares,compared with £6,031 through conventional brokers.
