Risk warning: Most beginners lose money. This is education, not financial advice. Learn the maths before you fund.

Many beginners fund $10 and hope to double it in a week. The maths says the opposite.

5 WINS × $1= $55 LOSSES × $2= $1050% wins — yetNET −$5Fix: risk less than you aim to make — see Risk-Reward 1:2
Five wins of $1 make $5. Five losses of $2 cost $10. Half wins, yet −$5 net — because risk was bigger than reward.

Win rate is not enough

Example:

  • You risk $2 to make $1 each trade.
  • You win 5, lose 5 out of 10 trades.

Result: 5 wins × $1 = $5. 5 losses × $2 = $10. Net –$5.

You won half the time, but you still lost. Risk was bigger than reward.

Costs eat small accounts

Spread (the small cost inside the price) and fees hurt small trades more. If you scalp for 5 pips with a 2-pip spread, cost is 40% of your move.

High leverage makes it worse. One 30-pip move against you on a large lot can wipe $10. See Leverage and Margin: The Double-Edged Tool.

How winners think

Winners risk small and aim for bigger reward than risk. Example: risk $1 to make $2. Then you can win less than half and still grow.

Bottom line: You risk small reward for big loss and high leverage, so you can win half and still lose; fix maths or you risk account death. Related guides: Forex Safety and Avoiding Scams.
