Quote side
Long entries and exits transact on different quote sides, as do shorts. Mid-price candles systematically omit the round-trip spread.

M1 candles are not ticks
MARGIN 26One-minute OHLC is an aggregation, not a tick-by-tick record. When entry, stop, and target fall inside the same M1 range, the candle cannot establish their order or whether the quoted spread allowed either fill. More M1 bars do not solve that sequencing problem.
Use bid and ask data when available, or disclose a spread model and conservative collision rule. Restrict entries to a written session, tag scheduled releases, and compare costs with the small distance the strategy expects to capture.
Long entries and exits transact on different quote sides, as do shorts. Mid-price candles systematically omit the round-trip spread.
Tick or sub-minute sequence is required for tight same-bar outcomes. Synthetic paths must be labelled and sensitivity-tested.
Include decision and order delay assumptions where targets are small. A strategy that needs the candle close cannot fill at that same close without delay.
M1 looks detailed only relative to larger candles; it may still be coarse relative to the trade.
M1 OHLC does not show the order of quotes within the minute. If entry, stop, and target share a candle, more years of M1 data do not resolve the trade; only finer sequence data or a declared assumption can do that.
At small targets, quote side and trading cost can dominate gross movement. Long entries and short exits use ask-side logic; short entries and long exits use bid-side logic. A mid-price touch may never have been executable.
| Measurement | How to define it | Why it matters |
|---|---|---|
| Ambiguity rate | Share of trades with multiple order events inside one M1 bar | Shows how much the result depends on missing sequence |
| All-in friction | Spread, commission, slippage, latency and rejected fills in R | Tests net rather than chart-only expectancy |
| Decision workload | Signals, misses, overrides, cooldowns and simultaneous trades per hour | Tests whether replay pace transfers to real time |
| Session tail | Cost and MAE/MFE distribution by session and event window | Identifies when average assumptions fail |
Candle count is not evidence quality. Highly overlapping trades, repeated minutes from one session, and unresolved fills can create a large but misleading sample.
