WHY BOTS FAIL

Myfxbook

Short answer

Myfxbook is described here only as a type of product: a track-record verification and statistics site, where a trading account is linked and its results are shown as charts and numbers.

This page is about the kind of product Myfxbook belongs to: a site that links to trading accounts and publishes their statistics. It explains how to read such a record, not whether to trust one.

The page explains the idea in plain words, works through the arithmetic with a table, and shows how it hits grid, martingale and DCA bots, then tells you what to check before you run one.

  • A worked example with real arithmetic
  • How it hits grid, martingale and DCA bots
  • How to check for it before you run a bot
  • No advice, no signals, no profit promises

Key facts

  • Myfxbook is described here only as a type of product: a track-record verification and statistics site, where a trading account is linked and its results are shown as charts and numbers.
  • Verifying that trades came from a real account is not the same as showing the account is typical, skilled or safe. A verified record can still be short, small, lucky or an account its owner picked out of many.
  • A short record has a wide margin of error. In a made-up twelve months the average was 1.83% a month but the margin of error was +/- 3.16, so luck cannot be ruled out (calculated by us on 31 Oct 2026).
  • Losses are harder to recover than they look. After a 30% loss you need a gain of 42.9% to get back to the old high, and after 50% you need 100% (exact).
  • Read drawdown, record length and how the account was run before return. See maximum drawdown and equity curve.

What a verification site is

An account owner connects a trading account to the site, usually with a read-only login. The site then pulls the trade history and shows it as a growth curve, a list of trades and a set of statistics such as gain, drawdown and trade count. The idea is that numbers taken straight from the account are harder to fake than a screenshot. How each site collects the data, what it checks and what it labels are facts you must read on its current pages. Different sites differ and change.

What verification can reasonably show is that the trades in the record happened in the linked account. What it cannot show is why the account exists, whether other accounts by the same person failed, whether the account is demo or live, or what happens next. Those are the questions that matter when you read a record. Some records on sites like this may come from demo accounts, which have no real fills and no real cost of failure, so check which kind you are reading.

The general risks of reading a record

Short history

Twelve months, or fewer, is one stretch of market. A record that has not met a sharp reversal has not been tested on one. Short records also let luck show as skill. See forward testing and overfitting.

Picked from many

If a hundred people each link an account, a few will have a strong curve by chance, and those are the ones with a reason to show it. A list ranked by gain mainly shows who was lucky or who risked the most. See survivorship bias.

Return without risk

A high gain can come from large risk. A record that shows a big return and a small drawdown over a short time may simply not have had its bad stretch yet. A record that holds losing trades open can show a smooth line of closed trades while the open loss grows. Check the equity line, not only the balance line.

Changed rules

A bot's settings can change inside one record. The curve you read may be several versions joined together, and the one you would run is not the one that made the early gains.

Worked example: what twelve months can tell you

Everything here is made up. A linked account has these twelve monthly returns, in percent: 6, -5, 8, -4, 7, 3, -6, 9, -3, 5, 4, -2. The average is 1.83 percent a month, which looks positive. The standard deviation, a measure of how much the months swing around the average, is 5.47 percent. The standard error of the average is the standard deviation divided by the square root of the number of months, which is 1.58 percent. A rough margin of error is two standard errors either side.

MeasureValue (percent)
Months12
Average month1.83
Standard deviation5.47
Standard error1.58
Rough range for the true average-1.33 to 4.99

Calculated by us on 31 Oct 2026. The range runs from below zero to well above it. So these twelve months cannot tell a skilled account from a lucky one, even though the average looks good and the record is real. More months narrow the range. Four times as many months would halve the standard error if the account stayed the same.

Why drawdown is read first

A fall of 30 percent does not need a 30 percent gain to undo. If the account is at 70 after starting at 100, it needs 100 divided by 70, which is 42.9 percent more. At 50 percent down it needs 100 percent. The deeper the fall, the more the account must do to return, so two records with the same total gain but different drawdowns are very different experiences.

The margin of error from twelve months is larger than the average itself. A longer record would shrink it.

How it hits bots

  • Grid and martingale bots can show a rising closed-trade line for months and then a single deep loss. See martingale.
  • Demo records have no real slippage. A live account running the same bot would pay costs the demo did not. See slippage.
  • Copying from a record adds delay and cost on top. See copy trading.

What to verify on the vendor's current pages

  • What the site says its verification checks and what it does not. Read its own wording, dated.
  • Whether a record is a live or demo account, and whether the page labels that clearly.
  • The length of the record, the largest drawdown and the equity line, not only the balance line.
  • Whether the owner has other linked accounts that are not shown.
  • What the terms say about accuracy and about your use of the statistics.

What this page does not tell you

It does not say whether the site or any record on it can be trusted. We have not run the product, and it states nothing about its features, accounts or users. It says what a verified record can and cannot show. The numbers are made up and nothing here is a recommendation.

FAQ

Frequently Asked Questions

What kind of product is Myfxbook?

In general terms it belongs to the class of track-record verification and statistics sites, where a trading account is linked and its results are shown. We have not run it, so check its current pages.

Does a verified record mean the trader is skilled?

No. Verification can show the trades came from the linked account. It cannot show skill, safety, or that other accounts did not fail.

How long a record is long enough?

There is no fixed number. In our made-up twelve months the margin of error was wider than the average, so the record could not separate skill from luck.

What should I check on the vendor pages?

What verification covers, whether an account is live or demo, record length, the largest drawdown and any hidden accounts. Note the date you read them.

Can following a record lose money?

Yes. Past or simulated results are not a guide to future results. You can lose all the money you put in.

Are the numbers on this page real?

Example numbers are made up to show how the maths works, and the page says so. A figure only counts as exact when the page says it was calculated on a stated date. Nothing you enter in a calculator leaves your browser.

Can I use this to decide whether to run a bot?

It can show whether a bot's numbers hold together and how much an account can lose. It cannot say what the market will do, and it is not advice. Use it to ask better questions, then read the terms of your own broker or exchange.

Is this financial advice?

No. It is general education. All example numbers are made up and nothing here is a recommendation to follow any account.
