MT5 stops at the 1-minute chart. Advanced Seconds Chart MT5 goes below it!
Building real sub-minute OHLC candlesticks, directly inside MT5, with full access to every indicator and drawing tool you already use.
No plugins. No external feeds. Just attach it to a chart and go.
What It Does
The EA captures your broker's live tick stream and aggregates it into sub-minute candles via a custom symbol. Every MT5 feature works natively and you can attach indicators and other technical tools.
You pick the seconds. Need 25 second candles. Done. Need 45 second candles. Easy. Just adjust in configurations to your needs.
One-click duration switching. Seven on-chart buttons (1s, 2s, 5s, 10s, 15s, 20s, 30s). Click one and the chart rebuilds in under a second. No restarts, no dialogs.
Price source selection. Bid, Ask, Mid, or Last. Mid averages bid and ask per tick, producing cleaner candles on pairs with variable spreads.
Spread filter. Set a max spread in points. Ticks that arrive during blown-out spreads are discarded, keeping your candles clean through news and rollover.
Instant backfill. Loads up to 1 hour of candles from stored tick history the moment the EA starts. No waiting for bars to accumulate.
Live Info Panel
A compact, repositionable dashboard updated every second:
- Bar countdown — seconds until the current candle closes
- Tick count — activity on the current bar plus session total
- Live spread — current spread in points, always visible
- Multi-timeframe countdowns — up to three slots (e.g. M1, M5, H1) counting down simultaneously
Panel corner, margin, colours, font size, and opacity are all configurable.
Configuration
Bar Settings
Initial bar duration (default: 1s) — The starting candle duration when the EA loads. Can be changed at any time using the on-chart buttons without restarting.
Max bars to retain (default: 7,200) — Rolling buffer size. Once the limit is reached, the oldest bar is dropped as each new one is added. At 1-second resolution, 7,200 bars is 2 hours of history. At 30 seconds, it is 60 hours.
Backfill seconds (default: 3600) — How many seconds of tick history to read from your broker on startup. Increase this if your broker stores deep tick history and you want more bars available immediately. (300 = 5 minutes, 3600 = 1 Hour)
Auto-open chart (default: true) — When enabled, the EA automatically opens the custom symbol chart on launch. Disable if you prefer to open it manually from Market Watch.
Price and Filtering
Price source (default: Mid) — Which price from each tick is used to build candles. Bid and Ask use the raw quote. Mid averages the two, smoothing out spread-induced noise. Last uses the trade price, relevant for futures and equities.
Max spread filter (default: 0 / off) — Maximum allowable spread in points. Any tick where the spread exceeds this value is discarded entirely. Useful for filtering out distorted price action during news events, rollover, and low-liquidity sessions. Set to 0 to disable.
Info Panel Display
Show info panel (default: true) — Toggles the entire dashboard. When disabled, no panel or labels are drawn on the chart.
Show duration buttons (default: true) — Toggles the row of 1s/2s/5s/10s/15s/20s/30s buttons. Can be shown independently of the info panel.
Panel corner (default: Left Upper) — Which corner of the chart the panel and buttons anchor to. All four corners are supported: Left Upper, Right Upper, Left Lower, Right Lower. Repositions automatically on chart resize.
Panel margin (default: 18px) — Distance in pixels between the panel edge and the chart corner.
Text colour, font size, background colour, border colour, opacity — Full visual control over the panel appearance to match your chart theme.
Multi-Timeframe Countdowns
Extra countdown 1 (default: M1) — First countdown slot. Displays a live countdown to the next candle close on the selected timeframe.
Extra countdown 2 (default: M5) — Second countdown slot.
Extra countdown 3 (default: off) — Third countdown slot. Set any slot to "Current" to disable it.
Setup
- Drag it onto any chart you want sub-minute charts for
- Adjust preferences or use default settings
- Click OK. The seconds chart opens automatically.
30 seconds from file to live candles.
Pro Tip: The seconds chart will open with the Default template (green/white candles and black background), if you want it to match your chart colours with indicators etc. save your template as Default and every new chart will have your preferred set up. Do NOT attach the Seconds Chart to your chart and save as Default template as it will keep opening charts.
Use Cases
Scalping. See entries and exits at the resolution they actually happen. A 1-minute candle hides dozens of micro-structures that matter when your holding time is measured in seconds.
News trading. Watch the initial spike, the pullback, and the continuation unfold bar by bar in the seconds after a release, rather than waiting for a single 1-minute candle to close.
Execution analysis. Compare your fill times and prices against the actual 1-second price action to understand slippage and timing.
Learning price action. Studying how candles form at the 1-second level builds intuition for structure and momentum that translates directly to higher timeframes.
