What Is Copy Trading? How Copied Results Diverge

Copy trading is an arrangement in which orders placed on one trading account are automatically reproduced on another, so the follower holds broadly the same positions as the source. The follower delegates entries, exits and timing, but keeps their own broker, their own account size and their own fills. That last part is why two accounts following the same signal almost never end the month with the same number.

How it works

A copier sits between the two accounts. It watches the source for a new order, converts the size, and sends the equivalent order to the follower's account, usually within a fraction of a second. Closes, partial closes and stop modifications are relayed the same way.

The conversion step is where most of the outcome is decided. Three modes are common:

Fixed lot      follower lot = 0.10                                 (same size every trade)
Proportional   follower lot = source lot × (follower equity / source equity)
Risk-adjusted  follower lot = follower equity × risk% / (stop distance × pip value)

Fixed lot ignores account size entirely and is the mode that ruins small accounts copying large ones. Proportional keeps the ratio but inherits the source's risk appetite whole. Risk-adjusted is the only mode that is really position sizing rather than mirroring, and it requires the source to use stops.

Three things then pull the copied result away from the original:

• Latency. The copier reacts after the source fills. On fast entries the follower buys a slightly worse price, every time, in one direction. That is structural slippage, not bad luck.
• Spread and commission at your broker. The source's edge was measured against the source's costs. Your spread is a different number on the same instrument at the same second, and it is subtracted from every trade.
• Account size and rounding. Minimum lot steps force rounding. On a small account a 0.03 lot signal becomes 0.01 or 0.10, and the proportion the copier was built to preserve is gone.

Why it matters

You inherit the source account's drawdown without inheriting the reason the trader stays in it. The person running the strategy knows why the position is open. You see only the loss, which is why followers usually disconnect near the bottom of a decline that the source rides out.

Costs also compound against you. A strategy with a small average win per trade can be profitable on the source's cost structure and unprofitable on yours, with identical trades, purely through spread and commission. Before copying anything, the source account is what you audit — not the marketing around it.

What the data shows

Across the public accounts on ShowMyTrades with trading history (August 2026), the median closed trade lasts 2.4 hours and the median account has 171 closed trades. Short trades are where copier latency does the most damage, because a fixed delay is a larger share of a two-hour move than of a two-week one.

Venue matters too, and it varies enormously: the connected accounts sit on 703 distinct broker servers, and 429 users run accounts at more than one broker. The same strategy is genuinely executed at hundreds of different cost structures here.

The risk you would be adopting is not small either. The median deepest drawdown on those accounts is 9.7%, but 38.2% have been more than 20% below their peak and 17.6% have lost more than half of it. And of 10,000+ published accounts, only 65 carry Track Record Verified — provenance is the exception, so check it before you copy.

Where you see it on ShowMyTrades

The trades table is the due-diligence tool. Every closed trade shows Open Time, Close Time, Type, Symbol, Open Price, Close Price and Net P/L, with S/L and T/P on by default and Duration, Swap, Commission and Magic available from the column menu. That is where you see whether entries are reachable at your latency and whether the strategy actually uses stops — which decides whether risk-adjusted copying is possible at all.

In Advanced Statistics, the Trades section carries Avg. Trade Length, Total Commissions and Total Swap Paid: the source's real cost load, which yours will differ from. The Performance Metrics section carries Expectancy, the average result per trade that your extra spread eats into, and Z-Score (Probability), which says whether wins and losses arrive in streaks — the streak is what a follower has to sit through.

Breakdown Statistics shows trade count and profit per symbol, split into Longs, Shorts and Total, so you can tell whether the record rests on majors or on instruments where spreads diverge most between brokers. The header's Info group names the platform, broker and leverage the record was produced on. None of the three is necessarily yours.

Common misunderstandings

• "Same signals means same results." It does not. Different broker, different fills, different costs, different size. Divergence is the default, not a malfunction.
• "Proportional sizing makes it safe." It makes it scaled. A 40% drawdown proportionally copied is still a 40% drawdown.
• "The provider takes the risk." The provider takes a fee. The margin call arrives on your account.
• "A long track record on the source is enough." Only if the data path is verified. Without third-party verification, a long record is a long claim.
