Why frequency and exposure matter
Many traders focus on entries and exits, but ignore how often and how long a strategy trades. Two strategies with identical metrics can feel completely different because:- one trades rarely and stays flat most of the time
- the other trades constantly and is always exposed
Frequency and exposure define lived risk, not just statistical risk.
Trade frequency
Trade frequency is how often a strategy opens trades. It depends on:- timeframe
- entry logic strictness
- filters (trend, session, volatility)
- market volatility
- 2 trades per month → low frequency
- several trades per day → high frequency
What low frequency implies
Low-frequency strategies:- have fewer trades
- rely on larger moves
- often look cleaner in backtests
- have higher uncertainty per result
- results depend heavily on a few trades
- harder to validate statistically
- long periods of inactivity
What high frequency implies
High-frequency strategies:- produce many trades
- rely on small edges
- are sensitive to costs and slippage
- reveal weaknesses faster
- noise sensitivity
- overtrading
- execution assumptions matter more
Exposure time
Exposure time measures how long the strategy is in a position. Example:- exposure = 80% → strategy is in the market most of the time
- exposure = 20% → strategy is mostly flat
- market risk
- drawdown sensitivity
- emotional pressure
Frequency vs exposure
These are related but not the same. Examples:- low frequency + high exposure → long-term trend following
- high frequency + low exposure → scalping / fast mean reversion
- high frequency + high exposure → often dangerous
- low frequency + low exposure → very selective strategies
Why exposure often hides risk
A strategy can look safe because:- win rate is high
- drawdowns look moderate
- it may be exposed during every major market move
- risk compounds during volatility spikes
How to read results
Exposure explains many confusing results.
How filters affect frequency
Adding filters almost always:- reduces trade count
- reduces exposure
- increases selectivity
- eliminate valid trades
- create misleading backtests
- cause long flat periods

Common mistakes
Judging a strategy by win rate alone
Judging a strategy by win rate alone
High win rate strategies often trade frequently with small edges and hidden exposure.
Ignoring exposure duration
Ignoring exposure duration
Long drawdowns feel worse when the strategy is always in the market.

Best practices
- Know how often your strategy trades
- Check exposure before trusting returns
- Ensure trade frequency matches your psychology
