Many traders only focus on the size of the spread, ignoring a key fact: transaction costs are charged based on the number of lots or nominal amounts. The higher the leverage and the heavier the position, the greater the proportion of the cost to the principal for the same spread. The cost is not a fixed percentage, it changes with your position and leverage.

The cost is calculated based on the position, not the principal.

Spreads, commissions, and overnight interest are almost all charged based on the number of trading lots or the nominal amount. This means: No matter how large or small your account capital is, as long as the position is the same, the spread cost is the same. But the proportion of cost to principal is completely different - when the account is small and the position is heavy, the cost proportion will be significantly magnified. When comparing costs, you should not only look at the "spread number", but also look at the "ratio of cost to principal."

How Leverage Amplifies Cost Proportion

To illustrate with an illustration (the numbers are only examples): the same spread of US$0.35, with a principal of US$1,000 and a position of 0.1 lots, is exactly the same as a principal of US$5,000 and a position of 0.1 lots, but the spread cost is five times different. The function of leverage is to allow you to open a larger position with less principal, so the higher the leverage, the higher the proportion of the same cost in the principal. When trading frequently, this "blood loss" will be accumulated repeatedly, especially for small accounts.

Overnight and slippage are also magnified by position

Overnight interest is calculated based on the number of lots. The larger the position, the higher the daily cost; slippage is reflected in price points. The heavier the position, the greater the profit and loss amount corresponding to the slippage. These costs amplify linearly with the position, but they are not easily noticed at ordinary times. In other words, if the same strategy is applied to accounts of different sizes, the impact of cost on net worth is completely different. Small accounts should regard cost as the first priority. It is more useful to memorize the "cost is magnified by position" than to memorize the spread number.

How to control cost ratio

The first is to control the combination of positions and leverage: leverage is a tool, not a goal, and the position size must be based on an affordable cost ratio. The second is to settle accounts before high-frequency trading: when entering and exiting frequently, spreads and commissions will be charged repeatedly, and the accumulated costs may exceed profits. The third is to set an upper limit on costs: incorporate the “proportion of single cost to principal” and “total monthly cost” into trading disciplines, and stop trading if they exceed the limit. The fourth is to distinguish between nominal costs and real costs: the platform displays nominal spreads, and what you really pay is the proportion of your principal. Fifth, check platform reports regularly, check actual costs with real transaction records, and adjust positioning habits in a timely manner.

Take cost ratio into consideration

Applying this logic to the platform, WMAX provides materials for evaluation: the spreads, overnight interest, and contract specifications of each variety are publicly disclosed. Traders can calculate the cost amount corresponding to their planned positions based on this, and then convert it into a proportion of the principal; the platform's simulation account is suitable for first using different leverage and position combinations to trial the cost ratio, find a match that suits them, and then enter the real offer. It should be noted that the platform data is a reference, and the calculation and decision-making of cost ratio are ultimately completed by the traders themselves. Whether WMAX is suitable for you depends on your principal size, position habits and sensitivity to cost ratio.

write at the end

Cost is not an isolated number. It is multiplied with leverage and position to determine how long your principal can last. Seeing the true proportion of costs to principal is more valuable than chasing smaller spreads. Regardless of whether you choose WMAX or other platforms, it is recommended to first use simulated trading to try out the cost ratios of different positions, then enter the real trading with appropriate leverage, and always control the risk within an acceptable range. Leveraged trading carries high risks. Please fully understand the relevant rules before entering the market and make prudent decisions.
