Pips, Ticks and Points

Q: What is a pip worth exactly?

It depends on lot size and the pair. On a standard lot of 100,000 units with the dollar as quote currency, a pip is worth around $10; on a mini lot of 10,000, one dollar; on a micro lot of 1,000, ten cents. In pairs where the dollar is not the quote currency, pip value fluctuates with the exchange rate and has to be recalculated. Most platforms display it already converted in the order window.

Q: What is the difference between a tick and a point?

The point is a full unit of price; the tick is the minimum tradeable fraction of that point. In the E-mini S&P one point is four ticks of 0.25, so a point is worth $50 and a tick $12.50. Confusing them when calculating a stop produces a factor-of-four error in that contract, and other factors in other products, because the relationship between point and tick is not the same everywhere.

Q: How does tick size affect liquidity?

Directly, and in two opposing ways. A large tick forces a wide minimum spread, which makes each trade more expensive but incentivises market makers to quote because their margin is guaranteed. A small tick allows very tight spreads, making trading cheaper, but fragments the book across many levels with little volume at each. Exchanges calibrate this figure seeking the balance, and sometimes adjust it when they observe one of the two effects dominating.

The minimum units of movement in each market and how to convert them into money: the elementary arithmetic that prevents order-of-magnitude sizing errors.

Why Each Market Has Its Own Unit

Every market defines a minimum price increment below which quoting is impossible. It is not an arbitrary convention: it sets the granularity of the order book, conditions the minimum width of the bid-ask spread, and determines how much money the smallest possible move represents. The names change by market — pip in currencies, tick in futures, point in indices, cent in shares — and confusing them produces calculation errors that are rarely small: usually a factor of ten or a hundred, which is exactly the size of error that wipes out an account.

Pips in Currencies

In the currency market, a pip is traditionally the fourth decimal place of the exchange rate. If EUR/USD moves from 1.0850 to 1.0851, it has moved one pip. The systematic exception is yen pairs, quoted to two decimals, where the pip is the second: USD/JPY moving from 148.25 to 148.26 has moved one pip. Most brokers today quote an additional decimal, the pipette or tenth of a pip, which allows tighter spreads. Converting to money depends on position size: on a standard lot of 100,000 units, a pip is worth roughly $10 when the dollar is the quote currency; on a mini lot of 10,000, one dollar; on a micro lot of 1,000, ten cents.

Ticks in Futures

In futures, the tick is the contract’s minimum increment and its dollar value is set by the exchange, not the trader. The most traded cases are worth memorising: the E-mini S&P has a tick of 0.25 points worth $12.50; the micro E-mini, $1.25. WTI crude has a tick of $0.01 per barrel which, over 1,000 barrels, is worth $10. Gold has a tick of $0.10 per ounce over 100 ounces, that is $10. The 10-year note quotes in thirty-seconds, an inherited convention that surprises anyone coming from other markets. Knowing what a tick is worth is what lets you translate a "four-tick" stop into a concrete dollar figure before sending the order.

Points and Cents

In indices, a point is one full unit of the index, and its dollar value depends on the product multiplier: an S&P point is worth $250 in the full-size contract, $50 in the E-mini and $5 in the micro. In shares, the minimum increment is one cent for the vast majority of stocks, and over a hundred shares one cent equals one dollar. In options, the minimum increment is usually $0.01 on low-priced contracts and $0.05 on more expensive ones; since the multiplier is 100, a $0.05 move in the premium represents $5 per contract. In fixed income, the reference unit is the basis point, one hundredth of a percentage point.

The Check That Prevents the Expensive Error

Before sending any order in a new instrument, it is worth answering two concrete questions: what is one tick worth in money? and how much do I lose if price moves ten ticks against me? It is a thirty-second calculation that prevents the most expensive error of all, which is getting the order of magnitude wrong. Real cases abound: trading a full-size contract believing it is the micro means ten times the intended exposure; assuming a pip is worth $10 while trading mini lots distorts the entire sizing. None of these errors is sophisticated, and that is precisely why they keep happening.

Why do some options quote in $0.05 increments and others in $0.01?

Because of the exchange’s minimum increment programme, which applies finer steps to low-priced options — typically under $3 — and $0.05 steps to more expensive ones. The logic is that a cent on a $0.40 premium is reasonable granularity, while on a $25 premium it would produce an unnecessarily fragmented order book. Some very liquid underlyings also participate in reduced-increment programmes.

What is a basis point?

One hundredth of a percentage point: 0.01%. It is the standard unit in fixed income and interest rates, where the relevant changes are small and speaking in percentages would be imprecise. When a central bank "raises by 25 basis points", that means 0.25 percentage points. It is also common in management fees: a fund charging "30 basis points" charges 0.30% a year.

How does tick size affect liquidity?
