The main thing from the US on the cheapy brokers were they sell any information they have on you and your activity, as does Facebook apparently etc. (wish I had realised this better when FB fell to $20). Knowing what people want to buy is given to trading bots to front run the prices so you pay more in the spread and also a bot will buy the stock a moment beforehand and raise the price slightly before its passed onto you. Its still useful for small investors, if you are right about the buy. Flat fees are largest to the smallest investors. Vice versa, anyone in size should go nowhere near these If Segro is a good tip, I'd rate the whole FT250 so long as its also correct Sterling is rising quarterly etc I think it relates to UK prospects which is mostly contained or described by the next 250 stocks after the top 100 which are sometimes companies with no trade at all in the uk.
