Key Automation Question: How does the payout work? Weekly or monthly ?

IX Global doesn't touch your broker account, the only thing connected is the automation service so you can withdraw and deposit as and when you want.    What you earn in your trading account is yours and you deposit and withdraw from your broker account as you like.

However to benefit from the opportunity to increase your lot size and compound interest -it's best to keep all your equity in your broker account. If you do withdraw try to limit it to about 30% but really its up to you!
