# Trade Frequency & Exposure

> How often your strategy trades, how long it stays in the market, and why both define real risk.

## 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

<Info>
  Frequency and exposure define *lived risk*, not just statistical risk.
</Info>

## Trade frequency

**Trade frequency** is how often a strategy opens trades.

It depends on:

* timeframe
* entry logic strictness
* filters (trend, session, volatility)
* market volatility

Examples:

* 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

Risks:

* 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

Risks:

* 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

High exposure increases:

* 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

But:

* it may be exposed during every major market move
* risk compounds during volatility spikes

## How filters affect frequency

Adding filters almost always:

* reduces trade count
* reduces exposure
* increases selectivity

But too many filters can:

* eliminate valid trades
* create misleading backtests
* cause long flat periods

## Common mistakes

<AccordionGroup>
  <Accordion title="Judging a strategy by win rate alone">
    High win rate strategies often trade frequently with small edges and hidden exposure.
  </Accordion>

  <Accordion title="Ignoring exposure duration">
    Long drawdowns feel worse when the strategy is always in the market.
  </Accordion>

  <Accordion title="Comparing strategies with different frequency">
    Always normalize expectations when comparing low- vs high-frequency systems.
  </Accordion>

## Best practices

* Know how often your strategy trades
* Check exposure before trusting returns
* Ensure trade frequency matches your psychology
* Compare strategies with similar frequency profiles
