Frequently Asked Questions

Compounding is the process of generating returns on both your initial principal and your accumulated past profits. By keeping gains in your trading account and dynamically scaling your position size with your expanding balance, account growth accelerates exponentially over time rather than linearly.

Professional institutional hedge funds typically aim for 15% to 30% annualized returns (roughly 1.5% to 2.5% per month). Consistently achieving 3% to 5% per month with strict 1% risk management places a trader in the top 1% of market participants globally.

The Rule of 72 is a mathematical shortcut to estimate the number of periods needed to double your capital: Doubling Periods ≈ 72 / (Growth Rate %). For example, at a 6% monthly return, your account doubles in approximately 72 / 6 = 12 months.

Monthly or trade-by-trade compounding based on fixed percentage risk (e.g. 1% per trade) is standard practice. Avoid high-risk 'daily compounding targets' (like promising 2% every single day), as no trader wins every day without taking catastrophic drawdown risk.
