I recall asking something similar a long time ago but never received a satisfactory answer. Why are the spreads when trying to buy some securites much higher than what i can buy using the bigger platforms like HL or Interactive Investor. For example i just tried to buy some Allianz Technology Trust and the quote on HL was a full 0.5 percent better than Trading 212. The other annoying thing with Trading 212 is you cant get a live quote before you confirm the order. The only way is to do a limit order but this is tiresome to always have to do this for small orders, first checking what you can get with another broker and then having to enter the limit order on T212.
I thought T212 use interactive brokers so why dont they have a live quote where you press confirm once your happy with it?
