Insights and Problems

01

Data Reliability Issues

Manual scraping of stock data often led to data loss, resulting in incomplete or inaccurate datasets. This made it difficult for users to fully trust the information used for analysis and decision-making.

02

Time-Consuming Analysis

Performing calculations manually was slow, delaying insights and reducing responsiveness to market changes. As a result, users often spent more time processing data than actually making strategic investment decisions.

03

Risk of Misjudged Opportunities

Inaccurate data and slow processing increased the risk of missing profitable stock investments. This could lead investors to overlook potential gains or make decisions based on outdated information.
