Break-Even

A price or win rate at which the specified model's net result is zero after included costs. The entry price is not necessarily the break-even price.

Illustrative example

How does it work in practice?

In a hypothetical model, you buy 100 units at 10 USD per unit and pay 5 USD in total entry and exit fees. An actual exit price of 10.05 USD per unit breaks even; exiting at 10 USD per unit leaves a 5 USD loss.

A case to work through

Costs on a short position

Model: sell 200 units at 12 USD; total costs are 8 USD and fill prices already include spread.

  1. Cost per unit is 8/200 = 0.04 USD.
  2. Repurchasing at 12 − 0.04 = 11.96 USD covers those costs.

What follows? Assess the threshold using costs and position direction.

Example boundary: Do not subtract a spread already included in fills again.

Text description of the diagram
  1. Cost per unit: 8 USD / 200 = 0.04 USD.
  2. Adjustment direction: For a short, reduce the repurchase price.
  3. Zero-result threshold: 12 − 0.04 = 11.96 USD.

A useful distinction

Break-Even / Take profit (TP)

Take profit is an exit instruction; break-even is a calculated zero-result level.

Check your understanding

Find the zero-result repurchase price for a short position.

Model: short 100 units at 20 USD, total additional costs 6 USD. Which repurchase price gives zero net P/L?

Show the answer and explanation

19.94 USD

A 100 × 0.06 = 6 USD price gain covers costs.
