Executable range
Estimate movement available after crossing the bid-ask spread. Mid-price high-low range overstates what a round-trip order can capture.
Editorially reviewed 24 August 2026
Quiet does not mean cheap
MARGIN 20A quieter AUDUSD period may show smaller candles without a proportionally smaller spread. For a scalper, the relevant comparison is not raw volatility but executable movement after spread, commission, slippage, and the time spent waiting for a valid setup.
Use source data fine enough to resolve the stop and target. If both levels sit inside one source bar, label the observation ambiguous or apply a conservative rule. A large number of M5 candles cannot repair missing tick sequence.
Estimate movement available after crossing the bid-ask spread. Mid-price high-low range overstates what a round-trip order can capture.
Match source granularity to stop and target distance. Synthetic lower-timeframe paths should be disclosed, never treated as observed ticks.
Report eligible signals per hour, overlap restrictions, time in market, and rejected high-spread setups beside expectancy.
Low volatility can reduce both risk and the movement available to pay transaction costs.
M5 OHLC retains more detail than M15 but still discards quote sequence. When entry, stop, and target share a candle, resolve the path from finer bid/ask data or score it with a fixed conservative assumption.
Liquidity and spread vary by session, rollover, event, and venue. Use the historical decision-time distribution rather than a single promotional minimum spread, and include rejected or missed setups in the workload estimate.
| Measurement | How to define it | Why it matters |
|---|---|---|
| Quote-side fill | Bid and ask triggers for each long and short order | Eliminates impossible mid-price entries and exits |
| All-in cost | Spread, commission, slippage, latency in pips and R | Converts gross scalp expectancy to net expectancy |
| Decision load | Eligible, missed, duplicate, late, and invalid signals per hour | Tests whether the workflow is operationally executable |
| Tail execution | Worst spread, gap, slippage, and MAE by session | Prevents averages hiding the loss-driving observations |
Manual replay can pause time and reduce pressure. Follow a timed decision routine, then use a real-time simulated stage to measure alerts, missed signals, and platform execution.
