iWeb or Halifax Sharedealing?

I find iWeb a very good value site for trading, with no platform fee. But don't be fooled by the valuations page which purports to show the value of your holdings. The cost-per-share valuations are based only on purchase price and do not change if you sell some, whether you sell at £1 or £1,000 a share. Relying on this valuation could prove costly. I have complained to iWeb without success, so make sure you keep an accurate record of trades to ensure you do not sell below your true average price.
Otherwise, excellent. I have had no issues with price-limit trades or range trading, although there is a £2 set-up fee for these if placed outside an ISA. The £2 is refunded on execution, but not if you change your mind.

I owe iWeb an apology. I am advised that it is normal to count only purchases to calculate the average cost of a share.

I had mistakenly believed that the correct way to calculate the average cost was to take the total amount spent after a series of trades and divide by the number of shares held at the end of the sequence. Apologies.
