Interestingly, the rules here prohibit me from meaningfully replying to an accusation posted by a Moderator. Well done.🙄

There are no accusations there. Obviously, it was harmless humor. Stop looking for negativity where it doesn't exist.

Thank you for informing me that it was a joke, as another Moderator. Therefore, the feeling of guessing is mutual.😉

No restrictions except traffic limits for specific access point and periods of liveupdate checkups.

Open "Help -> About" and restart the terminal to stimulate updates.

Hi Renat, thank you very much — it worked! After opening "Help → About" and restarting the terminal, LiveUpdate finally pulled the beta build, and I was also able to successfully connect Claude to MetaTrader 5. I really appreciate your quick help.

Missing FTP tab in Options after updating to Build 5984

After updating, the FTP tab is no longer present under Tools > Options. The tab bar now shows: Server, Charts, Trade, Experts, GPU, Events, Notifications, Email, AI Assistant, MCP, Community.

Previously this tab let you configure automatic FTP publishing of account reports (server, login, password, upload path, refresh interval). Is this intentional (i.e. FTP publishing has been deprecated), or a regression from the Options dialog rework that added the AI Assistant/MCP tabs? If it's removed for good, is there a supported way to replicate this via MQL5 (e.g. SendFTP ) for automated report uploads?

Terminal: Removed support for publishing trading reports via FTP. This legacy feature is deprecated and is no longer widely used.

Hello, after testing MCP server on MT5 build 6034 directly from copilot locally, these three items were discovered as possible issues/improvements. Maybe some are design choices but letting you know just in case.

Issue	Impact	Expected fix
list_open_charts  omits  chart_id  from every entry	Charts opened by the user or in a previous session cannot be closed or modified via MCP — the ID is irrecoverably lost	Each  { title, path }  entry should also include the  chart_id  integer
mcp_trade_allowed: true  is reported even when trading will fail	Agents that check this flag before placing orders receive a false green light; the actual blocker (AI Assistant → Trading: Enabled) is a third independent gate not reflected in the API	The field should reflect the true composite permission state, or the error response should explicitly name the ungated setting
trade_close_by_position  tool schema documents the second parameter as  position_by_ticket  but the server requires  position_ticket_by	Every caller following the documented schema gets  "position_ticket_by must be specified"	Fix the tool schema /  tools/list  description to match the actual accepted parameter name

Best Regards

I found a reproducible issue in the native MetaTrader 5 MCP

trade_send_market_order tool.

Environment:

- MetaTrader 5 x64 Build 6070

- Windows 11

- Demo hedging account

- External MCP client: OpenAI Codex

- mcp_trade_allowed: true

- experts_trade_allowed: true

- Broker execution mode: Market Execution

Symbol conditions:

- Symbol: US100Cash

- SYMBOL_TRADE_EXEMODE: 2 (Market Execution)

- SYMBOL_FILLING_MODE: 2 (IOC only)

- Minimum volume: 0.1

MCP request:

{

  "symbol": "US100Cash",

  "type": "sell",

  "volume": 0.1

}

Result:

{

  "retcode": 10030,

  "retcode_details": "Invalid fill"

}

Terminal journal:

send market order market sell 0.1 US100Cash

failed market sell 0.1 US100Cash [Unsupported filling mode]

market order market sell 0.1 US100Cash failed: #10030 Invalid fill

Control tests:

1. The same US100Cash 0.1 market order succeeds when placed manually.

2. trade_send_pending_order succeeds when filling_type="return" is used.

3. The pending order triggers successfully.

4. trade_close_single_position closes it successfully using IOC.

5. Supplying an additional filling_type="ioc" property to

   trade_send_market_order does not change the result.

6. All 1,557 symbols returned by this broker have

   SYMBOL_FILLING_MODE=2, so native MCP market entry is unusable

   for this broker.

The trade_send_market_order MCP schema does not expose a filling_type

argument.

Expected behavior:

trade_send_market_order should either:

- automatically select ORDER_FILLING_IOC according to

  SYMBOL_FILLING_MODE, or

- expose a filling_type argument like trade_send_pending_order does.

Actual behavior:

The market order is sent with an unsupported filling mode and the

trade server returns TRADE_RETCODE_INVALID_FILL (10030).

Please check the filling-mode selection or conversion in the native

MCP market-order implementation.

Hi MetaQuotes team,

I would like to clarify the officially supported external API usage of MQL5 Lite / InferDeck.

MetaTrader 5 automatically provisions the credential used for MQL5 Lite, and https://api.inferdeck.net publicly exposes an OpenAI-compatible /v1/chat/completions API.

For an external unattended Python application running on a Windows VPS, used only for AI analysis and with no MetaTrader trading/write permissions, is there an officially supported way to call MQL5 Lite through:

https://api.inferdeck.net/v1/chat/completions

without exporting or accessing MetaTrader's automatically provisioned hidden credential?

Specifically:

1. Can a normal MQL5 OAuth access token be used as Authorization: Bearer ... with InferDeck, or is another user-managed API credential/token exchange required?
2. If another credential is required, where can an MQL5 user officially create and revoke it?
3. What exact model identifier should be used to select MQL5 Lite?
4. Does the free MQL5 Lite entitlement include external automated API calls, or is it limited to the built-in MetaTrader/MetaEditor Assistant?
5. What rate limits, quotas, pricing and automation/API terms apply to this usage?

If external use is supported, could you please provide the relevant official documentation or example authentication flow?

Thank you.
