Copy trading with MetaTrader 5: how trades are copied
Copying trades has a very convenient side and a side that almost nobody explains: risk does not travel with the trade. The symbol, direction and levels are copied, but your size, your spread and your latency are different from those of the source account. This article explains what is replicated, what is adapted and how to copy without taking on a risk you do not understand.
What copy trading is (and what it is not)
Copy trading consists of replicating in one account the trades executed in another. When the source account opens a position, the destination account opens its own; when it closes it, so does the destination. That is the whole mechanism.
- It is not a fund or a guaranteed product: the result depends on the market, just as if you had decided on the trade yourself.
- It does not eliminate risk: it shifts it to deciding ‘who I copy and with what size’.
- It does not exempt you from knowing: you can copy for months without understanding anything and still lose, but without knowing why.
The three models that exist
| Model | How it works | Advantage | Limit |
|---|---|---|---|
| Manual signals | The mentor publishes the alert and you execute manually | You control the size and the timing; you learn by watching the levels | It depends on you being there; your price will not be theirs |
| Copying on the broker's server | The broker itself replicates between accounts on its platform (PAMM, MAM, social trading networks) | Minimal latency and near-automatic setup | Only between accounts and symbols at the same broker; your risk control is usually limited |
| Local bridge | An intermediary program reads what is published by the source account and applies it to the destination account | It works across different brokers and symbols; each account decides its size; keys are not shared | There is latency (from one to a few seconds) and it requires a computer to be switched on |
The size problem: the number one mistake
It is the point that damages the most accounts. Imagine a source account with €10,000 that opens 0.50 lots; you copy it in a €1,000 account. If you replicate its lot, your relative risk is ten times theirs. If the trade goes wrong, the loss that is 1% for them is 10% for you.
What is copied is the idea: the symbol, the direction and the distance to the stop. The size is recalculated with your capital and your risk percentage. The full explanation, with examples in gold, forex and Volatility, is in the guide to calculating the lot per trade.
What is copied and what is not
Copied
- Symbol and instrument.
- Direction (buy or sell) and entry timing.
- Stop and target levels.
- Closes and, if the system supports it, partial closes.
Not copied (and it must be resolved)
- The lot: it is recalculated based on risk for each account.
- The price: your spread and your latency are not theirs.
- The symbol name: each broker uses its own; they must be mapped.
- Currencies: if your account is not in the same currency, there is conversion.
- Judgement: if you understand why it enters, copying becomes learning.
Latency and slippage: where money is lost without realising it
In a quiet forex pair, entering two seconds later barely changes anything. In synthetic indices such as Crash or Boom, where the violent event happens in seconds, two seconds can be all the difference: the price may have moved exactly in the direction of the event and your entry can end up miles away. If the stop is also close, your real risk is not what you had calculated.
- Consequence for the calculation: add a margin to the expected risk when copying in instruments with abrupt events, or avoid copying at those moments.
- Consequence for record-keeping: note in your journal which trades were copied. If the result is systematically worse than the source's, it is latency or size, not bad luck.
How we do it at the academy
We use a local bridge (the TITAN BRIDGE): a program that runs on the student's computer and reads the published signals —symbol, direction, levels and status— from a private key. Three design decisions that make the difference:
- The key lives in the connector, not in the expert. The expert installed in MetaTrader 5 only talks to your own computer: there is no need to authorise external servers or expose addresses.
- The signal is shared, not the order. You see the level on your chart and decide; the size is calculated by your account using your risk.
- No promises of results. The bridge solves a communication and logistics problem; it does not turn a bad trading approach into a good one.
When copying makes sense
- To learn execution: seeing how a stop is placed and when a position is closed, on your own chart.
- To cover hours you cannot be available for, always with reduced risk and knowing which logic is being replicated.
- As a bridge towards autonomy: the reasonable goal is to understand the method, not to depend on someone else's alert forever.
And it makes no sense when the only reason is 'I want to win without looking'. At that point copy trading stops being a tool and becomes a comfortable way of losing control.
Frequently asked questions
What exactly is copy trading?
Replicating in one account the trades executed in another: symbol, direction, timing and levels. The size adapts to each account. It is not a guaranteed product or a fund: it is replicating decisions with the same market risk.
Do you copy the same lot size as the mentor?
It should not be. The same lot size in an account ten times smaller is ten times more relative risk. The right thing is to recalculate the size using your risk and the same stop distance.
What is the difference between copying within the broker and copying with a bridge?
The broker's internal copying is almost instantaneous but only works between its accounts and symbols. A local bridge works between different brokers and lets each account decide its size, in exchange for somewhat more latency and needing a computer switched on.
How much latency is there when copying a trade?
From milliseconds with the broker's internal copying to one or several seconds with an internet bridge. In calm instruments it barely matters; in Crash or Boom, where the event happens in seconds, it can change the entry price a lot.
Does copying eliminate the risk of losing?
No. It changes who decides the entry, not the nature of the market. If the source account loses, you lose with it and also with your own conditions: spread, latency, size and your account currency.
What is the TITAN BRIDGE?
The local connector we use at the academy: it runs on the student's computer, reads the published signals from a private key and makes them visible on their chart. The key lives in the connector, the expert only talks to your computer and each account decides the size.
Copy with judgement, not blindly
At the academy, copy trading is used as a learning tool: you see the levels on your chart, calculate your size and understand why an entry is made. The decision is still yours.
