The scaling plan of Alpha Capital Group, as part of their Alpha Pro Plan, is designed to enable growth of capital through structured increments. To scale up your account, you need to have a 10% gain each time. This gain must be in your account when you ask to scale up, and money you've already taken out doesn't count towards this 10% gain. 

For instance, if you start with $100,000 and earn a 10% gain, which is $10,000, your new balance is $110,000. Now, you can ask to scale up your account and also take your performance fee, a portion of the profits made, which is 80% of the gain. In this case, you get $8,000, and your new starting balance for the next round is $110,000. In the next round, if your starting balance is $110,000 and you gain another 10%, which is $11,000, your balance goes up to $121,000. Again, you can ask to scale up and take your 80% performance fee. This time, you'll get $8,800, and your new starting balance for the following round is $121,000. 

Each successful cycle of achieving a 10% gain and scaling up by an additional 10% leads to a compounding effect. Additionally, the plan outlines a maximum capital limit, which, in the case of Alpha Capital Group, is stated to be up to $2 million. The scaling plan operates within Alpha Capital Group's broader trading framework, which includes a daily loss cap set at 5% of the opening amount for each trading day and a 10% maximum loss from the initial starting amount across all challenges.
