Often, a strategy that looks great in backtests fails to match that performance when you invest real money. This is not because of the strategy or the logic. The gap is due to execution infrastructure. It can vary based on the type of account, order routing, and cost structure. Backtests usually don’t represent the overall trading environment.
Order Routing and Realized Cost
Each fulfilled trade goes through a routing process, which determines the price the trader receives compared with the stated price when the trader clicks to place the order. The two most prevalent retail forex and CFD routing architectures are:
In a dealing desk model, the broker may offset traders’ trades and create prices in-house. Spreads may be fixed during periods of low volatility, while during high-impact news periods, pricing and execution conditions may vary at the broker’s discretion.
Orders are passed to a liquidity provider via an ECN or STP network in a no-dealing-desk model. Prices rely on aggregated market data, and spreads are variable depending on actual liquidity. The broker usually charges a separate commission for each trade lot. Traders regularly check a RoboForex Review before evaluating the routing quality among different brokers.
This difference is most crucial during volatile sessions, where a stable quoted spread can mean the difference between a short-term trading strategy being profitable or not.
In a dealing desk model, slippage may depend on the broker’s execution process, while in a no-dealing-desk model, slippage is based more directly on the market conditions when the order is placed. This can work either for or against the trader, depending on how the market moves when the order is executed.
Account Tiers as a Cost Function
Account type is not merely marketing branding, as people assume. It is a cost function based on trading volume and frequency. The table below outlines how the typical tier structure can affect the split between spread cost and commission cost.
| Account Type | Typical Spread | Commission | Best Suited For | Capital Requirement |
| Fixed/Spread | Fixed | Usually included in spread | Position traders and traders who prefer predictable costs | Low to medium |
| Standard | Wider, usually variable | Uncommon or none | Low-frequency trading | Low to medium |
| Cent/Micro | Variable, usually wider | Rare | Small-scale strategies and traders testing with limited capital | Minimal |
| ECN | Near-market, tighter | Usually charged per lot | Active traders and medium- to high-frequency strategies | Low to moderate |
| Institutional/Pro | Tightest available | Reduced or tiered | High-volume and professional traders | High |
Not all brokers use the names above. It is still crucial to verify the conditions: the spread range and commission. You should study how the order gets executed in connection to each tier before committing your money. The same tier might have different conditions depending on the provider.
The cost is also variable depending on the amount traded. While a wider spread can be more expensive per trade, a trader who trades only a few times a month might realize net savings by using a commission-free account.
This calculation is reversed for traders who make dozens of moves every day. The reduced spread across multiple trades may outweigh the cost of the fixed commission in an ECN account.
Regulatory Framework and Capital Protection
The regulatory jurisdiction dictates where client funds are held and what options are available in case of a dispute. Usually, entities under the control of well-established financial regulators keep client funds separate from their working capital and maintain minimum capital reserves.
According to Investopedia, regulatory risk is not limited to fraud. It also covers changes in the rules, which can impact trading conditions even after an account has been funded.
One related consideration is negative balance protection. If the jurisdiction implements this protection, client losses will not exceed the amount held in the account, even during significant market movements when the value of assets drops.
This protection helps prevent an account from going negative in the event of extreme volatility. A trader with multiple accounts in different geographical regions must know which legal entity each account belongs to, as even traders using the same broker name may not be protected in the same way.
A slightly more complicated part of client fund segregation is how likely you are to have access to your funds if your broker runs into financial trouble. Money in segregated accounts is usually held separately from the broker’s operating funds and is more likely to be clearly recognized as customers’ money.
On the other hand, money held in a broker’s general operating account is subject to greater risk if the broker experiences financial trouble.
An explicit written statement of the segregation policy will give you a better idea of how well your funds are protected than a marketing statement.
Infrastructure in Line With Strategy
The development and implementation of each strategy will have different infrastructure requirements. The differences in platform and account requirements include:
- Scalping and high-frequency strategies require low latency and tight spreads. They are more likely to be offered through an ECN or institutional-level account. They may, however, require more capital.
- The spread becomes less significant when considering longer time frames, which is often the case for swing and position traders, with overnight financing costs and platform robustness taking greater precedence.
- Algorithmic trading strategies should be evaluated to determine whether they are suitable for trading without restrictions. Some brokers may have different procedures for manual and algorithmic trading.
- News-based strategies are quick-action strategies that capitalize on market-moving news. This requires infrastructure capable of carrying out such strategies without excessive slippage or temporary suspension of quotes during high-impact news events.
There is a relationship between strategy selection and account selection. No matter how strong the logic is, any strategy based on tight spreads will perform worse on a wider-spread, commission-free account.
Vladyslav Kushneryk, CBDO at TopBrokers, says traders should look beyond the platform interface when comparing brokers and account types. “A trading platform is only the visible layer of a much larger execution system. For active traders, the real questions are how orders are routed, how consistently they are filled, what the true cost per trade is, and whether the account structure matches the strategy being used. A platform may look excellent, but if the underlying execution model works against your trading style, that difference will eventually show up in performance.”
For this reason, active traders should evaluate the platform, account type, and execution model as a single system rather than treating them as separate features.
Evaluating Platform Reliability
Cost structure is important, but you cannot neglect platform reliability. Important metrics include order speed during periods of low and high volatility and the percentage of orders filled near the requested price. Evaluate the platform availability during important economic data releases, when volatility is high, and servers may be under greater stress.
It is also a good idea to check withdrawal processing times, as a trader’s ability to manage risk across different accounts or reallocate funds between trading strategies can be greatly affected by this.
In a Nutshell
The way trades are structured and executed can have a massive impact on trading outcomes and development of the trading strategy itself. Once a trader has looked at the routing options, trading levels, and regulatory protections, they can select the infrastructure that is best suited to the trading strategy they are executing, rather than one that jeopardizes that strategy.
