Price history doesn't correspond?

Yeah when you compare charts you’ll want to look at ISA/Invest VS external. (The CFD spread is specific to T212)

However bear in mind that T212 is plotting the ASK in ISA/Invest.

If you look elsewhere it’s usually showing trades which is actual prices paid (either a buy or a sell).

In the case of MTO it’s just a stock split 97/50 that hasn’t been historically adjusted in T212 prior to the 14 July.

What I don’t understand is they wouldn’t be reporting this with a split

The shares tumbled 45% after the rights issue shares were admitted to 46.95p by mid-morning.
