Market Hours on MT4 and MT5 in South Africa | FxPro

How to apply market hours on MT4 and MT5

Market hours integration on FxPro MT4 and MT5 is achieved by using the broker server time as the base and then adding visual tools that map global forex sessions onto the chart. MT5 has native session tools and direct access to MQL5 indicators, while MT4 relies fully on third-party indicators for session highlighting. For South African traders, market hours are typically aligned to SAST (UTC+2), so indicators and Expert Advisors need to be configured with a GMT offset of +2. Once the offset is set, charts can display Sydney, Tokyo, London and New York sessions in local time, including key overlaps such as London-New York around midday to afternoon SAST. Automation is applied through MQL4/MQL5 EAs that filter trading by time of day, pause trading outside selected hours, or adapt risk to session volatility. Session tools do not change prices or execution; they only filter or highlight data so a trader can focus on preferred windows. The same approach applies to both live and demo accounts.

A typical setup looks like this:

Platform time and SAST alignment

Both platforms display FxPro server time, which cannot be changed directly in the terminal. All tick data, candles, order timestamps and historical records are tied to this server time. For South African clients, this means local time must be mapped to server time, usually through an indicator or through mental conversion.

Key points for alignment:

• The Market Watch window always shows prices in server time.
• Local SAST (UTC+2) can be displayed using a local-time indicator that shows a second clock or labels on the chart.
• Most session indicators from the MQL community include a GMT offset parameter; setting it to +2 aligns sessions with South African time.
• When daylight saving shifts occur in London or New York, the relative distance to SAST changes, so indicator settings may need a one-hour adjustment.

Using market hours on MT5

MetaTrader 5 offers native tools that make session management more straightforward. Market Watch allows monitoring of active instruments and session statuses, and the platform supports 21 timeframes so the same session can be viewed on multiple scales.

To apply market hours on MT5:

For algorithmic trading, MT5 allows Expert Advisors to include rules such as:

The MT5 Strategy Tester uses historical data based on real session conditions, so backtests can incorporate session logic and check performance in different time windows.

Using market hours on MT4

MT4 does not include built-in session shading, so traders rely on custom indicators from the MQL4 community. These indicators typically mark sessions with colored backgrounds or vertical lines.

Basic steps for MT4:

MT4 uses a 32-bit architecture and typically runs efficiently with a moderate number of charts and indicators. When running several charts with session tools, it is practical to:

Session-based trading configuration

Once visual session tools are in place, trading rules can be organized around those hours. Typical configuration options include:

• Enabling One Click Trading during high-liquidity overlaps to react faster to price changes.
• Setting calendar or custom alerts around key macro releases, such as data that usually arrives mid-afternoon SAST.
• Running different strategies at different times (for example, a London breakout rule set and a New York reversal rule set on the same pair).

In both MT4 and MT5, custom scripts can automate repetitive tasks related to time:

These scripts and EAs are written in MQL4 or MQL5 and should be tested in the Strategy Tester before being applied on live accounts.

Time zone specifics for South African traders

Traders in South Africa operate in SAST (UTC+2), which interacts in a particular way with global sessions. Session openings move relative to SAST when other regions enter or leave daylight saving time.

Typical SAST timings:

|Session|SAST Open|SAST Close|Typical behaviour| |Sydney|22:00 Sun|07:00 Mon|Lower volume, wider spreads| |Tokyo|01:00|10:00|JPY pairs more active, moderate spreads| |London|09:00/10:00|17:00/18:00|Higher EUR volume, generally tighter spreads| |New York|14:30/15:30|22:00/23:00|USD pairs active, tight spreads| |London - New York overlap|14:30/15:30|17:00/18:00|Higher liquidity and typically tighter spreads|

These times can shift by one hour during March-April and October-November as Europe and the US adjust clocks. Advanced indicators can account for daylight saving automatically, while simpler tools may require manual update of the offset parameter.

Performance and practical setup

Both MT4 and MT5 handle session indicators efficiently on standard hardware. Resource usage depends on:

• Number of open charts.
• Complexity of applied indicators.
• Number of symbols streamed in Market Watch.

Indicative ranges:

• MT4: around 256-512 MB RAM per terminal with a few charts and one EA; session indicators add a small overhead.
• MT5: roughly 512 MB to 1.2 GB RAM, reflecting 64-bit design and broader symbol handling; session tools typically add 10-50 MB.

For stable performance with multiple charts, indicators and EAs, a system with at least 4 GB RAM is advisable. This is particularly relevant during high-volatility overlaps when tick flow is higher. Session-based strategies behave consistently across FxPro account types, as execution and spreads follow underlying market liquidity through each session.
