Risk warning: CFDs and spread bets are complex instruments and come with a high risk of losing money rapidly due to leverage. You can lose money on these products, and each provider publishes its own loss figure under FCA rules. You should consider whether you understand how they work and whether you can afford to take the high risk of losing your money. Automated and API trading can amplify losses through bugs, connectivity failures and runaway orders.
A change is filed under the week that holds its own date, as its source gives it. That is not always the week this site read it. The checked date beside each source is the day that page was last opened.
IG
Deprecation
IG is deprecating the streaming MARKET subscription in favour of PRICE. Raised on trading-ig on 15 Oct 2025; the library moved its streaming sample to PRICE on 16 Apr 2026. IG publishes a migration guide our reader could not open, so no deadline is confirmed. Community sourced.
Affected pages: the IG record, everything recorded for it as one file and its own RSS feed.
