盤前盤後的最熱門過濾器是如何計算的？

在篩選器中，您可以查看整個交易日的價格數據，這些數據分為盤前、常規交易時段和盤後交易時段。您可以分析盤前和盤後價格變動/變動百分比、盤前和盤後開盤價、最高價、最低價、價格和成交量等數據。

在分析盤前和盤後數據之前，您需要了解以下幾個特性：

1. 盤前和盤後列中的數據始終僅包含上一個交易時段的數據。換句話說，這些數據會在新的盤前交易時段開始時被刪除。

2.盤後數據僅在盤後交易時段內可用。因此，如果常規交易時段尚未開始，則包含盤後欄位的欄位將為空。

以下是盤前和盤後主要欄位的公式說明：

盤前漲跌和盤前漲跌幅

Pre-market Change = Close price of the pre-market - Close price of the previous regular session 

Pre-market Change % = (Pre-market Change / Close price of the previous regular session) * 100 

盤後漲跌和盤後漲跌幅

Post-market Change = Close price of the post-market - Close price of the previous regular session 

Post-market Change % = (Post-market Change / Close price of the previous regular session) * 100 

盤前從開盤價漲跌和盤前從開盤價漲跌幅

Pre-market Change from Open = Close price of the pre-market - Open price of the pre-market 

Pre-market Change from Open% = Pre-market Change from Open / Open price of the pre-market * 100

盤前跳空%

Pre-market Gap % = (Open price of the pre-market - Close price of the previous regular session) / Close price of the previous regular session * 100

盤前開盤價

Pre-market Open = The symbol opening price in the pre-market session

盤前最高價

Pre-market High = The highest symbol price in the pre-market session

盤前最低價

Pre-market Low = The lowest symbol price in the pre-market session

盤前價格

Pre-market Price = The symbol closing price in the pre-market session

盤前成交量

Pre-market Volume = The number of trading units (shares, contracts, etc) for the symbol in the pre-market session

盤後開盤價

盤後最高價

Post-market High = The highest symbol price in the post-market session

盤後最低價

Post-market Low = The lowest symbol price in the post-market session

盤後價格

Post-market Price = The symbol closing price in the post-market session

盤後成交量

Post-market Volume = The number of trading units (shares, contracts, etc) for the symbol in the post-market session
