Red flags in "guaranteed" robots

Why martingale and grid robots show smooth curves and high win rates until one loss undoes them, and the warning signs in robot and signal sales.

  • Work out the size of a martingale cycle's loss and how often it happens
  • Recognise the red flags in robot and signal sales, and what to check before you pay

An advert shows a robot that has won 97% of its trades for eight months. Both numbers can be true, and the robot can still empty an account in an afternoon.

Simulated trades, not a real robot. Each cycle doubles the stake after every loss until a win or the limit. Not a forecast.

This run climbs from $10,000 to $14,540 over 484 trades, and 230 of its 231 cycles end in profit. Then eight losses in a row cost $5,100 and it finishes at $9,440, below where it started. Press “Run 500 trades again”, then move the win chance to 50%: the curve still looks smooth for long stretches, and the big losses still come.

A martingale robot doubles the stake after every loss, so the first win recovers all the losses plus the first stake. Most cycles end in a small win, which is why the win rate looks extraordinary. The rare cycle where the losses keep coming costs everything the doubling has built up.

A grid robot opens another trade every few pips as price moves against it, often with no stop loss, and closes the whole group when price comes back a little. The shape is the same: frequent small wins and rare, very large losses. Losing trades stay open in floating loss, so they are missing from the list of closed trades until the day they are closed.

Red flags in robot and signal sales

  • Guaranteed or fixed returns, such as “10% a month”. No trading method can guarantee returns, and regulated firms may not promise them.
  • Screenshots with no verification. Images and statements are easy to edit. A verifiable record is connected read-only to the real trading account by an independent tracking service, and even then you need to check its length and drawdown.
  • Very short histories. A few weeks or months of a martingale looks like skill.
  • Martingale or grid behaviour: lot sizes that grow after losses, no stop losses, a win rate above 90% with an average loss many times the average win, or large open trades in floating loss.
  • “Lifetime licence” offers and countdown timers. Pressure to pay before you have had time to test.
  • Pressure to open an account with one broker through their link. The seller may earn a commission on every lot you trade, whether you win or lose.

The Protect Yourself course goes deeper on how signal channels on Telegram and Instagram earn money and on “account management” offers.

Try it

What would you do?

A Telegram channel with 40,000 members sells a gold robot: '97% win rate, 8 months, no losing month'. The proof is a set of screenshots. A lifetime licence is $499 today only, normally $1,499, and the robot 'works best' with one broker, opened through the channel's link.

Count the flags in the offer before you choose: there are five, and the screenshots are the only evidence.
