All EAs are a scam, why do people say such?

<p id="isPasted">While people often claim "all EAs (Expert Advisors) are a scam," it is more accurate to say that the retail market for EAs is saturated with high-risk or fraudulent products, though the underlying technology of automated trading is a standard tool for professionals.&nbsp;</p><p>The perception of EAs as a scam persists for several specific reasons:</p><p><strong>1. Manipulated Performance Data</strong></p><p>Sellers often use deceptive tactics to make a failing bot look like a "money printer":&nbsp;</p><ul><li>Curve-Fitting: Developers "over-optimize" an EA to fit historical data perfectly, but it fails in live markets because it has only memorized the past rather than identifying real patterns.</li><li>Fake Backtests: Screenshots of perfect upward-sloping equity curves are easily faked or created on demo accounts where factors like slippage and spreads are ignored.</li><li>Cherry-Picked Results: Vendors may run 100 versions of a bot and only show you the one that got lucky over a short period.&nbsp;</li></ul><p><strong>2. Dangerous "Account-Blowing" Strategies</strong></p><p>Many mass-market EAs use mathematically flawed strategies that create a false sense of security before causing a total loss:&nbsp;</p><ul><li>Martingale: The bot doubles the trade size after every loss. This results in a very high win rate initially but eventually leads to a total account wipeout when a long losing streak occurs.</li><li>Grid Trading: The bot places multiple buy/sell orders without stop-losses. This works in "sideways" markets but crashes during a strong, one-way trend.&nbsp;</li></ul><p><strong>3. Predatory Business Models</strong></p><p>Often, the EA itself is not the product, but a "lead magnet" for other scams:&nbsp;</p><ul><li>Broker Kickbacks: Scammers give away a "free" EA but force you to use a specific, unregulated offshore broker that pays them a commission for every trade you make.</li><li>The Upsell Funnel: A cheap $50 EA is often just a hook to get you to buy a $2,000 "Mastery Course" or "VIP Signals".&nbsp;</li></ul><p><strong>4. Technical and Market Reality</strong></p><p>Even "honest" EAs often fail because they lack human intuition:&nbsp;</p><ul><li>Rigidity: Algorithms cannot "read the room" or adapt to sudden geopolitical events, central bank announcements, or "black swan" events that a human might avoid.</li><li>Infrastructure Failures: If your internet drops or your VPS fails, a bot might leave a losing trade open without a protective exit, leading to catastrophic losses.&nbsp;</li></ul><p><strong>How to Identify a Legitimate Bot</strong></p><p>If you are considering an EA, look for these "Non-Scam" indicators:</p><ul><li>Verified Third-Party Data: Demand a link to a live Myfxbook or FxBlue profile with "Track Record Verified" and "Trading Privileges Verified" green checkmarks.</li><li>Hard Stop-Losses: A legitimate bot must have a predefined price at which it exits a trade to protect your capital.</li><li>No "Secret Sauce": Trustworthy developers will explain the basic logic (e.g., trend-following vs. mean-reversion) instead of hiding behind "proprietary AI secrets".&nbsp;</li></ul>
