MetaTrader 5 Problems and Fixes

MetaTrader 5 is reliable, but a wrong server, a disabled setting or a broker-side issue can stop it working. Below are the most common MT5 problems with a clear symptom, the likely cause and a known-working fix for each. Jump to your issue, or read through.

No connection

Symptom: The status in the bottom right shows "No connection" and prices are not updating.

Cause: Usually a wrong server, wrong login, or no route to the broker.

  1. Check your internet connection is working.
  2. Open File, then Login to Trade Account.
  3. Confirm the Server matches the one in your broker email exactly. Brokers often list several, such as BrokerName-Live and BrokerName-Demo.
  4. Re-enter your account number and password, watching for caps lock.
  5. Right-click the connection status and choose Rescan Servers or a different data centre.
  6. If it still fails, contact your broker to confirm the account is active and not in maintenance.

Invalid account or authorization failed

Symptom: You get "Invalid account" or "Authorization failed" when logging in.

Cause: The login, password or server does not match, or the account was reset by the broker.

  1. Copy the login (account number), password and server directly from your broker welcome email.
  2. Make sure you are using the trader password, not the investor (read-only) password.
  3. Pick the exact server from the dropdown, not a similarly named one.
  4. If you recently changed your password, log in with the new one.
  5. If nothing works, reset the password in your broker client area and try again.

Off quotes error

Symptom: Placing an order returns "Off quotes" and the order does not go through.

Cause: The price moved before the order filled, the market is thin, or the broker has no live price for that symbol.

  1. Increase the maximum deviation or slippage in the order window before sending.
  2. Avoid placing market orders in the seconds around major news.
  3. Check the symbol is actually trading and not closed for the session.
  4. Refresh the symbol by removing and re-adding it to Market Watch.
  5. If it persists on one symbol only, contact your broker as the feed may be down.

Trade context is busy

Symptom: You see "Trade context is busy" and cannot send an order.

Cause: Another order or an Expert Advisor is already using the trade thread.

  1. Wait a second or two and try again, as it usually clears itself.
  2. Close any order confirmation windows that are still open.
  3. If an EA is placing rapid trades, pause it before trading manually.
  4. Restart MetaTrader 5 if it stays stuck.

Market closed

Symptom: The order button is greyed out or you see "Market closed".

Cause: The instrument is outside its trading hours, or it is the weekend.

  1. Check the trading session for that symbol by right-clicking it, then Specification.
  2. Remember forex is closed from Friday evening to Sunday evening, and stocks and indices follow exchange hours.
  3. Confirm your broker is open and not in a holiday session.

Not enough money

Symptom: You get "Not enough money" when trying to open a trade.

Cause: Your free margin is too low for the lot size and leverage.

  1. Reduce the lot size. Use our free position size calculator to size correctly.
  2. Check your free margin in the Trade tab, not just the balance.
  3. Close or reduce open positions to release margin.
  4. Confirm your account leverage in the broker client area if the required margin looks too high.

AutoTrading disabled, EA or indicator not trading

Symptom: An Expert Advisor or indicator is loaded but not placing trades, and there is a sad face on the chart.

Cause: The AutoTrading button is off, or automated trading is blocked in options.

  1. Click the AutoTrading button in the top toolbar so it turns green.
  2. Open Tools, Options, Expert Advisors and tick "Allow Algo Trading".
  3. On the EA, open its properties (F7) and confirm "Allow Algo Trading" is ticked.
  4. Make sure the smiley face on the chart is smiling, not frowning.

Indicator not showing on the chart

Symptom: You attached an indicator but nothing appears.

Cause: The files are in the wrong folder, or the indicator drew off-screen.

  1. Open File, then Open Data Folder, then MQL5, then Indicators, and confirm the indicator file is there.
  2. In MetaTrader 5 use Refresh in the Navigator, then drag the indicator onto the chart again.
  3. Check the indicator did not draw far above or below the visible price. Press the "Auto scroll" and reset the chart scale.
  4. Restart MetaTrader 5 so it recompiles and reloads indicators.

WebRequest is not allowed

Symptom: An indicator or EA that checks a licence or fetches data shows "WebRequest is not allowed for URL".

Cause: The URL is not in the MetaTrader 5 allowed list. This is the most common Market Structure Pro install issue.

  1. Open Tools, then Options, then the Expert Advisors tab.
  2. Tick "Allow WebRequest for listed URL".
  3. Add the exact URL shown in the error, for MSP that is https://www.traderindicators.net
  4. Click OK, then remove and re-attach the indicator.
  5. See the full MSP install guide at /install if you are setting up Market Structure Pro.

DLL imports are not allowed

Symptom: An EA shows "DLL imports are not allowed".

Cause: The EA needs external DLL calls, which are blocked by default for safety.

  1. Only enable this for an EA you trust.
  2. Open the EA properties (F7), go to the Common tab, and tick "Allow DLL imports".
  3. If needed, also enable it in Tools, Options, Expert Advisors.
  4. Re-attach the EA to the chart.

Charts frozen or prices not updating

Symptom: The chart is stuck and the clock or prices are not moving even though you are connected.

Cause: A temporary feed glitch, a heavy template, or the terminal needs a refresh.

  1. Right-click the chart and choose Refresh.
  2. Switch the timeframe and switch back to force a redraw.
  3. Remove very heavy indicators or templates that may be lagging the terminal.
  4. Restart MetaTrader 5, and if it continues, reinstall from your broker.

Missing history or gaps in the bars

Symptom: Older candles are missing or there are gaps in the chart.

Cause: The history for that symbol and timeframe has not been downloaded.

  1. Scroll left on the chart to trigger a history download.
  2. Open Tools, Options, Charts and raise "Max bars in chart" to a large number.
  3. Right-click the chart, choose Refresh, and wait for the bars to load.
  4. For deep history, some brokers require you to open the symbol on a lower timeframe first.

Cannot find your broker server in the list

Symptom: When adding an account, your broker server is not in the dropdown.

Cause: You are using a generic MetaTrader 5 download, not your broker version, or the server list is out of date.

  1. Download MetaTrader 5 from your own broker rather than a generic source, so their servers are preloaded.
  2. In the login window, type the exact server name and press Enter to add it.
  3. Use File, Open an Account, search your broker name, and select their company.

High ping or slow execution

Symptom: Orders are slow to fill and the ping to the server is high.

Cause: You are far from the broker server, or on a slow or unstable connection.

  1. Right-click the connection status to see your ping and pick the fastest data centre.
  2. Use a wired connection instead of wifi where possible.
  3. For serious latency, run MetaTrader 5 on a VPS located near your broker server.
  4. Close other heavy apps and browser tabs using bandwidth.

Indicators or EAs disappear after restart

Symptom: Your tools are gone from the Navigator after closing and reopening MT5.

Cause: They were saved to the wrong data folder, or a different installation is being opened.

  1. Confirm you always open the same MetaTrader 5 installation, not a second copy.
  2. Place files via File, Open Data Folder, so they go to the correct MQL5 folders.
  3. After adding files, right-click Indicators or Expert Advisors in the Navigator and choose Refresh.

Terminal running slow or using high CPU

Symptom: MetaTrader 5 is sluggish and your computer fan is loud.

Cause: Too many open charts, heavy indicators, or a large journal and logs.

  1. Close charts you are not using and reduce the number of loaded indicators.
  2. Lower "Max bars in chart" in Tools, Options, Charts.
  3. Delete old log files from the Logs folder inside the data folder.
  4. Restart the terminal, and consider a VPS if you run many EAs.
