Every curve has a build. We show it.

This curve climbed for three weeks. Then came a single day.

That is Quantum Baron, recorded in our own snapshots between 22 March and 15 April 2026. Growth went from +236% to +297%, then to −99%. The drawdown went from 4.7% to 99.6%. The signal last delivered on 15 April. The product is still on sale in the MQL5 Market.

AlgoCheck puts two labels on that product page: risk class martingale on record, and largest loss the build allows unlimited. Neither is a forecast. Both describe how the thing is built, and the recorded history now stands next to them.

This build is the norm

We record 588 trading systems offered in the MQL5 Market, 437 expert advisors and 151 signals, and that number grows with the market.

The build is checkable on 60% of the living ones. Of those, around 8 in 10 carry martingale on record or a loss left open at the top. Roughly 1 in 5 shows observed stop discipline. 15% of the systems we recorded have left the MQL5 Market within four months, and their pages stay up with the last state we measured.

For the rest the page says "structure unchecked", because no trading account is available to us. That gap is ours, and it is stated in those words.

What every product page now shows

Build and maturity stand side by side, kept apart. The risk class says what the construction can do to an account. The maturity says how long the system has seen real markets: young, established, proven, proven over 8+ years. Neither is averaged into the other, so what the build can do stays visible however long the system has been running.

Every measured number carries the day it was taken. You see at once how fresh it is. Some figures were four months old.

When the live proof ends, the page says so, above every number, in a band across the full width. A provider can switch off their own live signal while the product stays on sale; that is the single most decision-relevant fact on such a page. Where our own snapshots evidence the collapse, they are printed with it. Where we cannot evidence one, we say that just as plainly.

Why the curve alone tells you little

A smooth equity curve can be produced in several ways. Martingale doubles into a loser until it comes back. Grid stacks positions against the move. Hedging holds both sides open. Positions that stay open show their damage later, so the balance reads calm while the account is anything but.

Before you buy, the market hands you one tool: the strategy tester, a backtest on historical prices. It shows what settings did to old data. What the build does to a live account over months stays out of view, and so does what became of the provider's other products. Those two gaps are ours to close.

A review is a snapshot. AlgoCheck keeps checking, and records what happens to a product after the marketing was written.
