Can anyone tell me how can I open a trade with leverage

I want to deposit 1k, but want to use only 100£ of my deposit and use some leverage to increase the order quantity.

in CFD when trading, all trades will automatically be leveraged against the entire balance of your accounts funds.

if you only want to use £100 then spend only that much when opening a position, but be aware the balance of the remaining £900 will fluctuate depending on whether or not the price moves in your favour.

the leverage ratio just kicks in to allow an account with a balance of just £100, trade up to a value of £1000 etc.
