Do separately for each terminal β Master one terminal, each Slave one terminal. No need to declare WebRequest URL.
Depending on how it's released, you get one of two forms.
MT5: copytradev5.ex5
MT4: copytradev4.ex4 + CT_Http.dll
Just copy the file, no need to compile.
copytradev5.mq5 / copytradev4.mq4 + folder Include\ + folder dll\
Must compile in MetaEditor.
Common requirement: Windows, MetaTrader 4 or 5 already logged into account.
Trong MT4/MT5: menu File β Open Data Folder.
Windows Explorer window appears. Each terminal has its own folder.
Before copying files β MT4/MT5 locks files while running.
This is where most mistakes happen. MT4 and MT5 do it differently.
copytradev5.ex5 (or .mq5) β MQL5\Experts\Include\, only if you have source code β MQL5\Experts\Include\, put next to file .mq5CT_Http.dll β do not need to copy. DLL is already embedded in .ex5, EA unpacks it itself MQL5\Libraries\ first runcopytradev4.ex4 (or .mq4) β MQL4\Experts\Include\, only if you have source code β MQL4\Experts\Include\, put next to file .mq4CT_Http.dll 32-bit version β MQL4\Libraries\. Required β MT4 cannot unpack itselfCopy the wrong version and EA does not run. The version in the package's mt4\dll\ folder is already the right 32-bit.
CT_Http.dll β Properties β if you see Security: This file came from another computer then check Unblock β OK.
Reopen terminal β Tools β Options β Expert Advisors.
Click OK, then click Algo Trading (MT5) or AutoTrading (MT4) on the toolbar to enable it xanh.
Click F4 from the terminal.
copytradev5.mq5 or copytradev4.mq4 in the folder tree Experts.
Click F7.
The window below should show 0 errors, 0 warnings. A few warnings are OK β 0 errors is what matters.
| Report error | Reason |
|---|---|
cannot open source file "Include\CT_Defines.mqh" | Folder Include\ does not sit next to the file .mq5/.mq4 |
cannot open file "dll\CT_Http.dll" (MT5) | Missing folder dll\ next to file .mq5 β MT5 embeds DLL at compile time |
Any timeframe, any symbol.
Navigator β Expert Advisors β drag copytradev5 / copytradev4 and drop on the chart.
Check Allow DLL imports. Required for MT4, recommended for MT5.
Fill parameters β see step 6 β then click OK.
CT_Http.dll. EA unpacks the DLL itself MQL5\Libraries\, in log βDLL installed. Please restart EA to load the DLL.β then detaches itself from the chart. Drag EA onto the chart again and it runs normally. Happens only once. If Experts tab shows "DLL in Libraries DIFFERS from version embedded in EA": trong MQL5\Libraries\ there is an old CT_Http.dll copy present, and EA cannot overwrite it. Fix: detach EA from chart β close terminal β delete MQL5\Libraries\CT_Http.dll β open terminal β attach EA again.
