Copier Not Opening Trades? The 9-Point Checklist That Finds It in Minutes
By Nexus Copier Team ·
The channel posts, your copier shows the message, and no order appears. Almost every case of this comes down to one of nine causes. Work through them in this order — it goes from most to least common, so you will usually stop early.
1. AutoTrading is off
The single most common cause. The AutoTrading button in the MetaTrader toolbar must be green, and the EA's own smiley face on the chart must be smiling, not showing a sad face or a cross. Both are required; one being right does not imply the other.
2. The EA is not allowed to make requests
If your copier reaches a cloud service, every URL it contacts must be listed under Tools > Options > Expert Advisors > Allow WebRequest. A missing URL here does not produce an obvious error — initialisation simply fails, and the terminal looks connected while nothing works. Add the URLs before activating the licence, not after.
3. The symbol cannot be resolved
The signal says GOLD, your broker calls it XAUUSD, and nothing matches. Check the log for the exact symbol string that was attempted, and confirm the instrument is visible in Market Watch.
4. The stop is invalid
Error 130 rejects the order entirely. The stop was too close to price for the broker's minimum stop level, on the wrong side, or unrounded. Nothing opens and nothing is lost, but the signal is gone.
5. Not enough free margin
An oversized lot relative to your balance and leverage is refused. This appears more often than traders expect after a run of losses, because free margin has quietly shrunk while the configured size has not.
6. The market is closed or the symbol is out of session
Weekend signals, indices outside cash hours and crypto-only weekend posts all produce a signal with no executable market. This is normal, not a fault.
7. A filter is silently doing its job
Spread filters, symbol filters, maximum-position caps, daily loss limits and news filters all block orders deliberately. If you configured a maximum spread of 20 points and the spread is 34, the block is correct behaviour. The log should say which filter fired.
8. The signal never parsed
If the message was an image, a voice note, or a format the parser did not recognise, there was no order to place. Check whether the copier logged a parse failure rather than an execution failure — they are different problems with different fixes.
9. The licence or connection is not actually active
An unset licence key, an expired trial or a broken link to the service leaves everything looking normal while nothing executes. Confirm the connection indicator reflects the copier service, not merely the broker.
How to make this diagnosable at all
Every item above is answerable in seconds if your copier writes a proper log line for each rejected signal — and close to unanswerable if it does not. Nexus logs the parse result, the resolved symbol, the computed lot, the validated stops and the broker's response for every signal, so "nothing happened" always has a reason attached to it.
Frequently asked questions
Why does my copier receive signals but not open trades?
In order of frequency: AutoTrading is disabled, a required WebRequest URL is missing, the symbol cannot be resolved to your broker's name, the stop is invalid, or a filter such as maximum spread is deliberately blocking the trade. The log tells you which.
What is the WebRequest allowlist and why does it matter?
MetaTrader blocks EAs from contacting any URL not explicitly listed under Tools > Options > Expert Advisors. If the copier's service URL is missing, initialisation fails quietly, so it is important to add the URLs before activating your licence.
How do I tell a parse failure from an execution failure?
A parse failure means no order was ever constructed — the message format was not understood. An execution failure means an order was built and the broker refused it. The log distinguishes them, and the fixes are completely different.
Can a filter block trades without telling me?
A well-built copier always logs which filter blocked a signal. If yours does not, spread filters and position caps are the usual silent culprits, especially during high-spread periods around news.
