CMC are a pain in the 'arris.
their trading platform freezes/kicks you out from time to time.
endless re-quotes on prices when trading over £15-20 a point
try withdrawing funds from your account (took over a week)
useless customer service
plus, the girls dont sound as nice.
ahem
with regard to capitalspreads - yes you can move a stop online to lock in profit. the only drawback i have found with CS is that you cannot place orders too close to the current price, and also if you scale into a position, it allocates a stop to each part of the position. so trailing a stop can be a time consuming affair..
other than that. great service. highly recommended.
