How to stop MetaTrader Terminal 4 [MT4] offline chart from updating the prices

How do I stop MetaTrader Terminal 4 offline chart from updating the price on its own?

I want to update the price on my own because of the difference in timezone with my broker. I have checked all the properties and the MQL4 forum. No luck.

Solution

  • For truly offline-charts, there is a way

    While regular charts process an independent event-flow, received from MT4-Server, there is a change for retaining your own control over TOHLCV-data records -- including the TimeZone shifts, synthetic Bar(s) additions and other adaptations, as needed.

    You may create your own, transformed, TOHLCV-history and import these records via F2 facility, called in MT4 a History Centre.

    How to avoid a live-quote-stream updates in MetaTrader Terminal 4

    The simplest ever way is not to login to any Trading Server. This will avoid unwanted updates from reaching your local anFxQuoteStreamPROCESSOR.

    There used to be a way, how to inject fake QuoteStreamDATA into a local MT4, however this enters a gray, if not black zone, as MetaQuotes, Inc., postulated the Server/Terminal protocol to be a protected IP and any attempt to reverse-engineer they consider an unlawfull violation of their rights and could cause legal consequences, so be carefull on stepping there. Anyway, a doable approach with an explicit risk warning being presented above.
