What monthly return is realistic in trading?+
The best-performing funds make 15-25% per year, barely 1-2% per month. A consistent retail trader at 2-3% monthly is already excellent. Distrust any promise beyond that.
Why does consistency matter more than big wins?+
Compounding rewards steadiness: +3% every month for 2 years makes +103%, while alternating +20% and -15% leads almost nowhere. Drawdowns break compounding.
Does the simulator account for taxes and fees?+
No — the monthly return you enter should be net of brokerage fees. Taxes depend on your country and status; keep a safety margin.
