A mathematical and statistical proof that signal services, copy trading, and trading info products cannot produce sustainable profit.
"I tried hard." "The instructor was the real deal." "Next time I will win." None of these subjective feelings matter. The reason you cannot win with copy trades, signals, or trading info products is that mathematics will not allow it.
This article sets emotion aside and explains in the language of probability and statistics why you cannot win.
| Market | Sum-game property |
|---|---|
| Spot FX | Zero-sum (one trader's gain is another's loss) |
| Index and commodity futures | Zero-sum |
| Binary options | Negative-sum (the house takes a large cut) |
| Crypto (short-term) | Effectively negative-sum (spread + fees) |
| Cash equities (long-term) | Positive-sum (dividends from corporate growth) |
Short-term trading in FX, futures, and crypto becomes negative-sum the moment you subtract spreads and broker fees. Aggregate participant P&L is below zero.
The broker earns on every trade you make, whether you win or lose. Signal providers and copy-trade operators are paid more when you trade more (typically through introducing-broker commissions). The accuracy of the signal is secondary.
Formula
EV = (win-rate × avg win) − (loss-rate × avg loss) − cost
Cost includes spread, commission, swap, and slippage.
Suppose a "good" signal has a 55% win rate and a 1:1 risk/reward (win +100 pips, lose -100 pips). On paper, this is profitable.
In practice:
Formula
EV = (0.55 × 100) − (0.45 × 100) − 3 = 55 − 45 − 3 = +7 pips → 700 pips/month
Mathematically positive — but the real question is whether the 55% win rate actually exists over time. In live FX/futures markets, a sustained 55% win rate is rare. Most "80%+ win rate" signals achieve their numbers by:
Real win rates converge near 45–50%. After costs, expected value is reliably negative.
Formula
Optimal fraction = (win-rate × odds − loss-rate) / odds
Even with a real 55% win rate at 1:1 R/R, Kelly suggests only ~10% of capital per trade. Most signal services push:
This is a design that guarantees ruin.
¥1M account, 20% risk per trade, true win rate 40%, R/R 1:1:
Formula
P(ruin) ≈ ((1 − Edge) / (1 + Edge))^(N) ≈ 97%
97 out of 100 traders blow up. The three survivors were simply lucky — no repeatable skill exists.
The screenshots you see on X and Instagram are fabricated through one of:
Free trials sometimes really do hit. This is a deliberate technique:
This is the classic pig-butchering pattern. "I won during the free trial" means only that you survived the filter.
Yes — but only the people doing the work themselves.
| Claim | Basis |
|---|---|
| Short-term FX/futures/crypto is structurally negative-sum | Spread and broker fees |
| "90% win rate" cannot exist sustainably | If real, the operator would not need to sell it |
| Signal services have conflict of interest | They earn from trade volume |
| Over-leverage produces ~97% ruin probability | Kelly criterion math |
| "Millionaire trader" screenshots are unverifiable | Demo/edit/theft trivially produce them |
The moment someone says "easy money", they have betrayed mathematics. A person who betrays mathematics will also betray you.
