$PSHG Interestingly T212 will only allow me to purchase shares in maximum increments of $1000 and no more than 5000 shares in total. To quote T212: Maximum trading quantities for both long and short positions are subject to immediate change, without prior notice. It can depend on multiple factors such as: Underlying market conditions - which include insufficient liquidity and unfavourable trading conditions. Control of exposure - Trading 212 manages its market risk to ensure it is not over-exposed to movements in any one particular stock. We have a regulatory obligation to minimize the risk of a single event causing us to fail. I wonder if T212 are expecting some unusual movement?
