Forex robots: reading the sales page before you read the code

How to read a vendor results page

Six things to look for, in the order they usually reveal a problem:

1. Is it live or backtested? Backtests are free to generate and free to redo until one looks good. Only a live, verified account means anything.
2. How long is the live record? Three months of a martingale system looks identical to three months of a genuine edge. Six months is a minimum; a year is better.
3. What is the maximum drawdown, in equity? Balance drawdown counts only closed trades, so a system holding a huge floating loss can show a clean balance curve indefinitely. Insist on equity.
4. What is the average loss versus the average win? Many tiny wins against rare vast losses is the martingale signature, visible even when the mechanic is not disclosed.
5. Was the lot size constant? Increasing size mid-record inflates the return figure without improving the strategy.
6. Which broker and account type? A result achieved on an unusually tight spread does not transfer to a standard retail account.

Martingale and grid, in plain terms

Martingale doubles the position size after a loss so that one win recovers everything previously lost plus a profit. Grid systems open positions at fixed intervals as price moves against them, achieving the same thing more gradually.

Both work most of the time, which is precisely the problem. If a trade goes against you 8 doublings deep, the position is 256 times the original size. The strategy needs price to reverse, and price is under no obligation to do so before the margin runs out.

The equity curve produced looks superb: a near-straight line up, tiny drawdowns, a very high win rate. It is not evidence of an edge. It is evidence that the losing sequence has not happened yet, and it will. The risk of ruin calculator makes the arithmetic concrete.

Some vendors disclose it. Many describe it as "smart recovery", "averaging" or "position management". If a system's drawdown looks impossibly small relative to its returns, that is the mechanic you are looking at.

Auto robot traders and robot trading

"Auto robot trader" and "robot trading" are search terms for the same category, usually reached by people looking for something that trades without them. Worth separating what is real from what is sold:

Real: software can execute a defined rule set continuously and without hesitation, across more instruments than a person can watch, honouring its stops every single time. That is a genuine and valuable capability.

Sold: that the software knows something about the market you do not. It does not. It applies rules a person wrote, and those rules were fitted to history.

The gap between the two is where the retail robot market makes its money. If you want automation, the honest route is to understand the strategy first and automate it second. Never to buy a black box on the strength of a curve.

What an automated system cannot do

Four limits are structural rather than a matter of build quality, and understanding them is most of what separates people who use automation well from people who lose money to it.

It cannot know what it has not been shown. A rule set encodes past relationships. When the regime changes (a trending market turns to chop, a correlation that held for two years breaks) the system keeps applying yesterday's logic with full confidence and no awareness that anything has changed.

Backtests overstate almost everything. A backtest with clean fills, fixed spread and no slippage is not a simulation of trading, it is a simulation of arithmetic. Add realistic spread, variable execution and the requeues that happen in fast markets, and a strategy that looked excellent frequently becomes marginal.

Optimisation finds coincidences. Tune enough parameters against enough history and you will find a setting that fits it perfectly. That setting describes the noise in that particular sample, not a property of the market, and it stops working the moment it meets data it was not fitted to. This is curve-fitting, and it is the single most common reason a purchased system fails.

Recovery logic hides risk instead of removing it. Martingale and grid systems produce beautiful equity curves for months, because doubling into a losing position converts many small losses into rare enormous ones. The curve is not evidence of an edge; it is evidence that the loss has not arrived yet.

The MarketPro Expert Advisor

MarketPro is building an Expert Advisor for MetaTrader 4 and MetaTrader 5. It is not available to download yet, and this page will say so until it is.

What is open today is the waiting list. Install the app, open the EA tab, and join it; everyone on the list is emailed when the builds go live. There is no charge and no card involved in joining.

When it does ship, three things will be true about it by design:

• You install and run it. It executes on your terminal, on your account, under your configuration. MarketPro never touches your account and exercises no discretion over your funds.
• It ships with a kill switch and an explicit as-is licence with no performance guarantee.
• Availability is limited by region. Distribution is restricted, and eligibility is determined by residence rather than by a checkbox on a page.

Meanwhile the thing that is live is the signal feed: vetted trade ideas with entry, stop and three targets that you place yourself. That is the manual equivalent of what the EA will automate, and it is available today with one free signal a day.
