The maximum amount you can invest in a single trade differs per product

For example, in the case of 'stocks' the maximum is usually £10.000. This means: If you open a position for £2.000 with a Multiplier of x5, this equals this maximum of £10.000 (5x 2.000 = 10.000).

However, other products can have different limits. 

See below an overview with the maximum trade size per product:

*There maybe some exceptions due to low liquidity of certain stocks

Please keep in mind: 

  • The absolute amount you can invest is dependent on the amount of money that is in your BUX X Account. 
  • You also cannot put your whole account into one trade only (this rule applies to account values exceeding £500 - Why? Have a read here).

  • A part of your total account value is reserved (called Ring Fenced). This amount is not available for trading as it functions as a back-up for possible fees.

Tip: If you want to invest more money in a certain stock or product, you can always open more than one position. You could for example open 2 positions of £10.000 in the same stock. 

Reminder: You can never lose more on a trade than your invested amount (see: why can I never lose more than I invest?)!
