Finding Equity Tick Sizes in NYSE and NASDAQ Rules

Summary

The document explains where to check minimum price increments for equities traded on NYSE Arca and NASDAQ, emphasizing exchange rule books as official references. It cites rules that set a one-cent minimum increment for securities priced at or above one dollar per share, with a smaller increment for securities below that threshold. It also mentions the SEC tick-size pilot program and related rule-book material.

These increments can help assess whether a vendor’s recorded price series contains values that are inconsistent with the applicable trading increment, which may reveal rounding or data-quality issues. The examples are specific to the cited rules and markets; they should not be assumed to cover every venue, security, or later rule change. A practical check needs the relevant venue, security price, and applicable rule version, particularly when analyzing historical data or securities affected by pilot-program provisions.

Key ideas

• Exchange rule books provide official minimum price increment definitions.
• The cited NYSE Arca and NASDAQ rules distinguish securities priced below one dollar from those at or above it.
• Tick increments can be used to check the plausibility of price-series precision.
• Applicable increments depend on venue, instrument, and the rule version in effect.

Answering this question is relevant to assess the quality of a time series in order to observe whether the data vendor applies some rounding to the data or is more decimal are present than the actual tick size.

In case of NYSE equities rule 7.6 reads: "The minimum price variation ("MPV") for quoting and entry of orders in securities traded on the NYSE Arca Marketplace is USD 0.01, with the exception of securities that are priced less than USD 1.00 for which the MPV for quoting and entry of orders is USD 0.0001."

For NASDAQ equities rule 4701 (k) reads: "The term "minimum price increment" means USD 0.01 in the case of a System Security priced at USD 1 or more per share, and USD 0.0001 in the case of a System Security priced at less than USD 1 per share."

In addition there is the SEC tick size pilot program (FINRA, SEC) which you can find embedded in the rule books as well.
