How do I deposit funds to MT4 and withdraw funds from it?

MT4 doesn’t have a deposit or withdraw function, but you can fund by logging into the Accounts dashboard clicking ‘add funds’ next to your MT4 account in the dashboard. You can also transfer funds to and from your MT4 account using your other tastyfx accounts, by going to the ‘live accounts’ tab and clicking ‘transfer funds.’ 

To transfer funds via the tastyfx app, first you will need to switch to your "Forex" named account via Accounts tab > Manage Accounts > then select switch account. Once that is done go back to the Accounts tab > Withdraw Funds > Transfer Funds (transfer the funds from the MT4 account to the Forex Web Trading Platform Account). Once the funds are transferred click on the withdraw funds button again and you will see the option to withdraw.
