Candle by Seconds for MT5 is a custom timeframe indicator that displays candlestick charts at non-standard sub-minute timeframes (e.g., 15-second, 30-second, 45-second candles). The standard MT5 platform supports timeframes from M1 (1-minute) and up; sub-minute custom timeframes require this category of indicator.
Risk disclosure: Sub-minute timeframes have unique characteristics including extreme noise and rapid execution requirements. See our full risk disclosure.
What Custom Sub-Minute Timeframes Show
Standard MetaTrader timeframes: M1, M5, M15, M30, H1, H4, D1, W1, MN1.
Custom sub-minute timeframes (15s, 30s, 45s):
- Aggregate tick data into shorter-than-1-minute candles
- Show micro-structure within typical M1 candles
- Used by scalpers and HFT-style traders
Use Cases for Sub-Minute Charting
Where sub-minute timeframes help:
- Ultra-short scalping strategies targeting 1-5 pip moves
- Order execution timing for traders manually executing fast strategies
- Market microstructure analysis for understanding tick-level patterns
- News-event analysis observing exact reaction patterns
Where sub-minute timeframes don't help:
- Strategies operating on H1+ timeframes
- Risk-averse traders (sub-minute amplifies noise)
- Traders without quality execution infrastructure
- Most retail trading scenarios
Practical Considerations
For traders using sub-minute timeframes:
Infrastructure requirements:
- Sub-20ms VPS-to-broker latency
- True ECN broker with raw spreads
- Sufficient account size for very-small-target trading
- See best forex VPS guide 2026
Strategy implications:
- Position sizing must account for spread cost relative to tiny targets
- Risk management must handle rapid execution
- Discretionary application requires intense focus
Verdict
Candle by Seconds indicator serves a narrow niche — traders specifically operating on sub-minute timeframes. For most retail traders, M1 and above provide adequate granularity.
For sub-minute applications, the tool works as expected. For non-sub-minute traders, the indicator adds no value.
