02. Reviewing

patterns of past stock charts

help understand current market flow.

Stock graph patterns repeat, thus it is important for investors to always review what happened in past stock market.

03. Existing services do not provide

past qualitative information

and are confined to numbers.

Majority of services show past data of companies with stock charts , but only give data confined to numbers such as price, tradings, or investor proportions.

Investors lack knowledge of

overall economy and companies
