Looked at a lot of chart feeds especially for forex and the CS one is fine, absolutely fine, as you would imagine given their wholesale forex business. it seems to mirror the currenex feed which is deep liquidity. IGs feed, on the other hand, seems a bit adaptive regarding spreads- My estimate is IG's spread on average, is more like 2 points than CS's one point. Get quote tickets open from both firms and see what I mean. Have noticed the odd weird issue with the quote tickets but very rarely and hasn't affected me. The new charts system from CS is fantastic quality for free, and it's just great to have Simon on here answering queries, long may it continue.
One tiny thing- would be good if I could change my password online!
