Everyone has an opinion but that doesn’t make everyone right…
You keep accusing t212 of the same thing and it is just plain incorrect. If you have any proof then put it out there (screen shots of their forum is not proof!). Not understanding how prices are displayed across different brokers and sources is also not proof that they are padding the spread. Your accusation is no different to the incorrect accusation about FT here: https://community.freetrade.io/t/sale-price-different-to-actual/
There are reasons to not like t212 (Eden has given some fair reasons) but your reasons are not fair or correct (unless you have evidence to the contrary).
