The minimum price increment at which a futures contract or other financial instrument can move. Each tick has a fixed dollar value that varies by instrument. For example, one ES tick equals 0.25 points ($12.50 per contract).
Why It Matters
- 1Tick size determines the granularity of your profit and loss calculations and directly affects your risk management precision.
- 2Instruments with smaller tick sizes allow more precise stop-loss placement and tighter risk management.
- 3When position sizing, you must know the tick value to calculate exact dollar risk per trade.
- 4Trading instruments without understanding their tick size is like driving without knowing how far a turn of the steering wheel will move the car.
Example
- 1ES futures have a tick size of 0.25 points and a tick value of $12.50. NQ futures have a tick size of 0.25 points and a tick value of $5.00. A 4-tick (1-point) stop-loss on ES risks $50 per contract, while the same 4-tick stop on NQ risks $20 per contract.
- 2To risk the same dollar amount ($100), you could trade 2 ES contracts or 5 NQ contracts with a 1-point stop.
Common Mistakes
- ✖Confusing tick size (minimum price movement) with tick value (dollar value per tick)
- ✖Not adjusting strategies when switching instruments with different tick sizes
- ✖Placing stop-losses at non-standard price levels that don't align with tick increments
