I experience the same problem - deleting the âwrongâ data doesnot help as they keep on refreshing. Any solution âŚotherr then âsellingâ the BPX and âbuyingâ them under a new asset in GBP - which I find cumbersom.
Yup, YF can have âmomentsâ of been unreliable ! It though features two listings for AVI Global Trust quoted in GBX - âLSE delayedâ and âCboe UKâ. The data for the latter doesnât seem to have any issues - Yahoo is part of the Yahoo family of brands.
Sorry to be saying this but I now realize AVI Global Trustâs historical pricing data thatâs available via its supposed Cboe UK listing on Yahoo hasnât changed since mid JuneâŚ
