For MT4/MT5 accounts, you can change the leverage value on the ‘Change Leverage’ page in your Members Area by simply selecting a new value and clicking ‘Change Leverage’.
Ensure you select the correct trading account for which you want to adjust the leverage.
Please note that it is not possible to decrease leverage if there are open positions in your trading account.
For R StocksTrader accounts, changing the account’s leverage is not available. However, you can open a new account with a different leverage value here.
