Why many trading systems fail.

The reality of the market

Anyone looking for an algorithmic trading strategy today will find a wide range on offer. Many systems advertise high win rates and seemingly proven mechanisms. At first glance, they are difficult to tell apart.

Based on our long-standing observation of the market, a very large share of the copy-trading strategies on offer is based on just two basic mechanisms: Martingale and Grid. This assessment is based on our own observation and does not claim statistical representativeness: it reflects what is regularly observed in practice.

The structural problem: The decisive point does not lie in the trading logic alone, but in the business model behind it. For many providers, remuneration is not tied to the user's result, but to order volume. The more trades are executed, the higher the spreads, swaps and volume-based remuneration, regardless of whether the user's account ends up in profit or in loss.

This document explains how the two most widespread mechanisms work and their known risks, and sets out the approach Solution Flow follows instead. It does not evaluate individual providers, does not make any recommendation, and does not make any statement about future results.

Martingale: how the system really works

The Martingale principle dates back to the 18th century and was originally developed as a betting strategy. The idea is simple: after every loss, the stake is doubled until a win occurs and offsets all previous losses. In trading, this principle is applied to position sizes. In the short term, this can work, provided enough capital is available and no extended losing streak occurs. That is exactly where the problem lies.

The mathematical reality: No real account can sustain this development indefinitely. In the classic implementation, there is no stop-loss, no automatic loss limit and no protective mechanism. A single unfavourable market phase can be enough to wipe out the account completely. On top of that: even with theoretically sufficient capital, the broker's margin requirements and maximum position sizes take effect much earlier in practice.

Who earns from this: Martingale systems generate very high order volume with exponentially growing position sizes. Every trade incurs spreads, swaps and commissions. In addition, many providers receive volume-based remuneration from the broker, typically in the range of about USD 3 to 15 per lot traded. Brokers and providers earn their revenue from trading volume, regardless of whether the user ultimately profits or loses capital.

Grid: structurally attractive, risky in the long run

Grid strategies follow a different principle: buy and sell orders are placed at regular intervals above and below the current price. The underlying assumption is that in any market movement, some position can be closed at a profit.

In sideways markets, this actually works and produces a deceptively high win rate. However, as soon as a sustained trend sets in, the number of open losing positions grows without control. Without a stop-loss, there is no brake. Some copy-trading platforms explicitly prohibit Grid strategies for exactly this reason.

• The longer a trend continues, the more open positions accumulate on the wrong side.
• The account is burdened by ongoing unrealised losses, without any automatic protective mechanism taking effect.
• Grid systems generate a very high number of trades per year, and with that, high volume-based revenue for brokers and providers.
• The performance history looks good during calm market phases, until the first strong trending move occurs.

Who earns from what?

The decisive difference between Martingale or Grid and Solution Flow's strategy software does not lie solely in the trading methodology, but in the revenue logic behind it.

Solution Flow's core principle: Solution Flow only receives remuneration when a realised profit above the previous high-water mark arises on the user's account. There are no volume-based fees, no kickbacks from the broker and no hidden revenue. The only revenue is the performance share on a high-water-mark basis.

Solution Flow's approach

A Martingale logic can be developed and programmed within a few days. The logic is simple; the risks are known. Solution Flow's strategy software, by contrast, is based on more than seven years of development, research and optimisation using real market data.

• No Martingale, no Grid. Every position has a clearly defined stop-loss and take-profit.
• Deliberately low order frequency. On average, only a few trades are executed per day instead of thousands per year.
• Multi-logic. Several sub-strategies are automatically combined and adjusted depending on the market phase.
• No arbitrary interventions. The software follows fixed rules, without after-the-fact rescue manoeuvres.
• Pure performance share. Remuneration exclusively from realised profits on a high-water-mark basis, the only revenue for Solution Flow.

What Solution Flow is not: Solution Flow does not provide financial services within the meaning of investment advice, portfolio management or financial intermediation. Solution Flow is not a broker and does not manage client funds. Access to trading and copy-trading systems is obtained at the user's own responsibility via external, licensed and regulated partner platforms.

The three layers of protection

While Martingale and Grid logics allow risk to grow without limit with every losing streak, Solution Flow's strategy software is actively safeguarded on three levels. This architecture is firmly embedded in the software.

In their classic implementation, Martingale and Grid systems have none of these three levels: no stop-loss, no break-even mechanism, no automatic adaptation to the market phase. The risk grows with every losing streak, or with every sustained trend, without any automatic limit.

Important: Protection at the position level limits the loss per trade, not the overall risk. Price gaps, extreme volatility or liquidity shortages can cause a stop-loss to be executed at a worse price than intended. A risk of loss, up to and including total loss, remains.

Risk of ruin: what the numbers say

The most meaningful metric for a trading strategy is not the maximum return achieved, but the probability of reaching a defined loss of capital. This metric is called risk of ruin.

Context: The risk of ruin is a statistical metric based on historical data. It is not a maximum loss, not a guarantee and not an indicator of future results. If market conditions change fundamentally, the informative value of the metric changes as well. Solution Flow provides the complete basis for this calculation, including the data basis, period and parameters, on request.

What this means for users

Anyone using an algorithmic trading strategy should understand how the system behind it works. The decisive question is not only how high the historical return was, but how the risk is structured and whose interests the strategy serves. Five questions to ask before any decision:

Role and limits of Solution Flow: Solution Flow provides algorithmic trading software. Solution Flow is not a broker, not a financial adviser and not a portfolio manager, and does not provide any financial services requiring authorisation. All trading decisions are made by the software on a rule-based basis. Users remain the full owners of their account and their funds at all times. Solution Flow never has access to client accounts or client funds.

Remaining risks: Even a rule-based strategy with defined loss limits does not rule out losses. Trading in financial instruments, in particular leveraged products, carries substantial risks, up to and including total loss of the capital used. Price gaps, exceptional volatility, technical faults, and failures on the part of the broker or the platform can cause protective mechanisms not to take effect as intended. Only capital whose complete loss is economically bearable should be used.

Conclusion

Martingale and Grid systems do not dominate the market because they are the best strategies. They dominate it because they generate reliable revenue for brokers and providers, regardless of the user's result. This is not an accusation against individual market participants. It is a structural feature of the market that should be named transparently, so that users can make their own informed decision.

Solution Flow's strategy software was created with the ambition of taking a different path: clear rules, defined risk limits, three active layers of protection and a remuneration structure that structurally aligns the interests of provider and user. This is not a promise about future results: it is the result of more than seven years of work.
