Zero-Sum Game

What is a Zero-Sum Game in CFDs Trading?

A zero-sum game means the total gains and losses across all traders add up to zero. If one trader wins 100 Dollars, another trader loses 100 Dollars. That is the basic zero sum game meaning and answers what is a zero-sum game in trading terms.

Why This Matters in CFDs

CFDs match buyers and sellers. Before costs, the long side’s gain equals the short side’s loss, so trading is zero sum. After spreads, commissions, and funding, the group outcome is slightly negative, since fees are paid out. Understanding this helps set realistic expectations and manage risk.

Zero-Sum Game Example

• Trader A buys 100,000 units of EURUSD at 1.10201 and closes at 1.10401. Move: 0.00200 = 20 pips if 1 pip = 0.00010. With 100,000 units, that is about $200 profit.
• Trader B sells 100,000 units at 1.10201 and closes at 1.10401. Trader B loses about $200.

Across both traders, profit and loss net to zero before costs.

Non-Zero-Sum Situations

Outside pure trading results, there can be non zero sum aspects. A hedger may accept a small trading loss in exchange for reducing business risk. In the broader economy, cooperation can create value, which people describe as a non zero sum game. But in CFD P&L terms, results between counterparties are effectively zero sum before fees.
