Frequently Asked Questions
Practical answers about PSE board lots, tick sizes, odd lots, and using these tools.
Find your stock's current market price in the "Market Price Range" column. The matching row shows the required shares per normal lot (board lot) and the tick size for that range. Orders are generally entered as one board lot or a whole-number multiple of it.
Type a stock price into the quick lookup field. As you type, the tool highlights the matching table row and shows the board lot, tick size, and estimated value of one board lot in plain language.
Live prices must come from your broker or a reliable market-data source. This tool does not fetch live prices; you enter the price yourself.
A board lot is the required normal-lot share multiple for a given price range. It is the standard quantity in which shares are normally traded. Orders are generally entered in one board lot or whole-number multiples of it.
It means valid normal-lot order sizes are whole-number multiples of the board lot. For example, if the board lot is 100 shares, valid quantities are 100, 200, 300, and so on.
The tick size is the minimum valid price movement for a stock in a given price range. Prices must move in increments of the tick size applicable to that range.
Find the board lot for your price in the table, then confirm your quantity is a whole-number multiple of that board lot. For example, with a 100-share board lot, 200 and 300 are valid normal lots while 250 is not.
For a normal-lot order, the minimum is one board lot for the applicable price range. Quantities smaller than one board lot are odd lots, which follow separate broker and PSE procedures.
No. The board lot depends only on the market price range, not on the stock symbol. Two stocks at the same price have the same board lot.
When the price crosses into a different range, the applicable board lot and tick size change to those of the new range. Always check the range that matches the current price.
Fewer shares than one board lot is an odd-lot order. Odd-lot availability and procedures depend on your broker and current PSE rules, so confirm with your broker.
An odd lot is any quantity that is not a whole-number multiple of the board lot. Odd lots trade through separate mechanisms; confirm availability and handling with your broker.
No. Estimated values exclude commissions, taxes, exchange fees, clearing fees, and other charges. They are illustrative estimates only.
A warning appears when the price you enter does not fall on the tick-size increment for its range. The tool does not silently round; it shows the nearest valid prices below and above so you can choose a conforming price.
Yes. You can enter any price you want to evaluate, such as a target buy or sell price. The tool applies the board lot and tick size for whichever range that price falls into.
The PSE can revise board-lot and tick-size rules from time to time. Always verify current requirements with official PSE publications or your broker.
Not necessarily. In December 2025 the PSE released a consultation proposal for a one-lot, one-share structure. Do not treat it as effective unless final rules and an official implementation date have been issued.
