Difference in price between estimated price and final price


I am about to place an order on a US order out of hours and the estimated cost is coming up £199.97. However, once I confirm the order the estimated cost changes to £181.83. Can anyone explain why there is such a big difference?


Check the actual share price on yahoo finance or google. The freetrade one is probably out of date.

US orders out of hours will have some adverse FX change baked in to ensure that the order can be filled. There was a user topic on this but struggling to find it

Thanks for the answers. So best to wait until the market opens again then?

I have looked on Google Finance, and Freetrade’s price seems to be correct even when accounting for any after hours trading for example.
