In the fast-paced world of CFD trading, success often hinges on understanding the numbers behind your trades. While many traders focus on entry and exit points, the impact of commission costs can make the difference between profit and loss.
When Markets Meet Mathematics
The global trading landscape presents a fascinating study of how different markets approach commission calculations. European traders face a distinctly different cost structure than their American counterparts, while Asian markets add their mathematical twist to the equation.
European Trading: Percentage Points Matter
Take a typical day in the European markets. A trader executing a position in Banco Santander faces a straightforward yet impactful commission calculation. With the standard European rate of 0.10%, a trade of 2,500 shares at €5.20 tells an interesting story:
The position value reaches €13,000 (2,500 × €5.20), resulting in a commission of €13.00 (€13,000 × 0.10%). While this exceeds the minimum €9.00 commission, smaller trades often trigger this threshold, fundamentally altering the cost dynamics.
Consider a smaller trade of 100 shares at €45.00. The €4,500 position would normally incur a €4.50 commission, but the minimum commission rule pushes the cost to €9.00, significantly impacting the trade's profitability threshold.

American Markets: The Per-Share Revolution
Across the Atlantic, U.S. markets take a remarkably different approach. The flat rate of 2 cents per share creates a linear commission structure that transforms how traders approach position sizing.
A trader taking a position in Apple with 1,000 shares faces a straightforward calculation: 1,000 shares × $0.02 = $20.00 in commission. This transparency allows for precise position planning, though the $10.00 minimum commission still catches smaller trades in its net.
Hong Kong's market adds another layer to the commission calculation story. At 0.18%, the rate exceeds European standards, creating unique considerations for traders. A position in Tencent Holdings worth HKD 350,000 generates a commission of HKD 630 – a significant factor in trade planning.

Breaking Even: The Numbers Game
The most crucial calculation in commission analysis is determining the break-even point. Modern traders must factor in entry and exit commissions, transforming the traditional break-even equation.
A $50.00 stock traded in the U.S. market demonstrates this perfectly. With 500 shares generating $10.00 in commission, each share carries an additional $0.02 commission burden. This pushes the true break-even point to $50.04, accounting for entry and exit costs.

Position Sizing: Finding the Sweet Spot
The mathematics of position sizing becomes particularly relevant when dealing with minimum commissions. European traders face this challenge daily. With a €9.00 minimum commission at a 0.10% rate, the minimum efficient position size calculation reveals the optimal trade value:
A position value of €9,000 marks the threshold where percentage-based commissions exceed the minimum charge. Below this, traders pay a higher percentage rate due to the minimum commission rule.
The TMGM Advantage
TMGM has structured its commission rates to provide clarity and competitive advantage in this complex landscape of calculations and costs. Standard account holders trading European shares face the familiar 0.10% rate but with optimized minimums that allow for more flexible position sizing.
Take a €20,000 trade in a European stock. The commission calculation remains straightforward at €20.00 (€20,000 × 0.10%), while professional accounts enjoy even more favorable rates, potentially reducing costs by 20% or more on larger positions.

Real World Application
The practical application of these calculations is evident in daily trading decisions. For example, a trader planning to build a 1,000-share position might consider the impact of scaling in through multiple entries.
Four entries of 250 shares in the U.S. market would each trigger the minimum $10.00 commission, totaling $40 – a significant consideration compared to a single entry commission of $20.
