Reading a company quote
What the price, range and activity figures measure, and which session each one describes.

Start with the session
A company quote is a collection of measurements, not a single live number repeated in different forms. On MockTradeCity's company page, the main quote summary describes Regular trading. Its large price is the latest Regular-session execution, expressed in City Coin (CC). During Overnight, Pre-market or After-hours, that main figure can remain at the completed Regular session's value while a separate line reports activity in the current extended session.
A new company may not yet have a Regular-session trade. In that case the page can use its listing reference price while showing dashes for an unavailable open, high or low. A reference price supplies a starting point, not evidence that someone traded there. The distinction matters when a listing is young or a session has just begun. A displayed number and an observed execution are not always interchangeable.
Four prices describe the day
Open is the first Regular-session execution of the day. High and low are the highest and lowest executions in that session so far. Previous close comes from the preceding Regular session's closing price. Overnight and extended-session trades have their own records and do not become today's Regular high simply because they occurred on the same calendar date. These labels define the set of trades behind the figures.
Suppose previous close is 50 CC, the first Regular trade is 51 CC, and subsequent trades reach 52 CC and 49 CC. The quote now has an open of 51, a high of 52 and a low of 49. A last trade of 50.50 CC leaves the daily change above zero despite the earlier move below previous close. The summary gives these landmarks, but only the chart or trade history reveals their sequence.
Ratios need a denominator
The daily percentage change compares the latest Regular price with previous close. The range percentage uses a different numerator: high minus low, divided by previous close. In the example, a 52-to-49 CC interval against a 50 CC previous close gives a six percent range. The last price can move within that interval without changing its width. This is why a small daily percentage move can coexist with a wide session range.
Share turnover rate is another ratio: Regular-session volume divided by the company's float. It compares traded share quantity with the quantity available for market circulation. It is not the percentage of unique shareholders who traded, because the same shares can change hands more than once. Historical high and low answer yet another question by placing the current quote against the company's longer price history rather than only today's activity.
Activity and company size
Volume counts shares traded during the selected period. Turnover totals each execution's price multiplied by its quantity, so its unit is CC. A company with a high share price can record more turnover than another company despite trading fewer shares. Both figures describe completed executions. They do not include every open order in the book, and they do not count a trade twice merely because it has both a buyer and a seller.
Market capitalization multiplies the share price by total shares, while float capitalization uses only floating shares. These measure company size at a price, not the amount of CC that entered the company today. The City Composite uses float capitalization in its weighting. Consequently, a large float-cap company can have more influence on the index than a smaller company with a larger percentage move. Market value is a valuation, whereas turnover is a flow of completed trades.
Where to read the quote in the city
The company summary groups these figures together. On a narrow screen, expanding the quote details reveals the same underlying measurements. The extended-session line includes its own label, price, percentage and last-trade time when data is available. Its percentage compares with the Regular close, so it can differ from the main percentage without either figure being wrong. The session label tells you which comparison you are actually reading.
The Market table places comparable figures side by side across companies and lets you sort supported columns. The company chart shows how the day's landmarks developed, while the Order book shows current interest and the trade list shows individual executions. Positions in Account uses your own entry cost for P&L, a different reference again. Keeping period, unit and denominator in view makes these pages fit together without expecting every displayed percentage to describe the same change.
