Minimum price fluctuation are the smallest increment of price movement possible in trading a given contract, this can also be referred to as a tick. When a security is traded on an exchange, the movement is measured in ticks. There are three different types of tick, plus, minus, and zero. A plus tick is when the price of the security is higher than the price it was bought at, a minus tick is when the price of a security is lower than what it was bought at, and a zero tick is when the price is the same. Ticks fluctuate throughout the entire trading day, and often don’t stay at the exact same number for long, so it’s important to stay updated and keep watching price movements of your purchased contracts.
