The current maximum order size is £100,000 per trade, and this applies across all markets - UK, US, and European stocks.
This limit is set per individual order, not per day. So if you wish to invest more than £100,000 in a particular stock, you can do so by placing multiple separate orders.
While most stocks on the platform trade well below this threshold for a single share, we’ve increased the limit to better support larger trades as our platform evolves.
If there are any future changes to order size limits, we’ll be sure to keep our customers informed.
