Open government data is a very helpful initiative to transfer the usefulness of data by putting all datasets in public domain. This data can be leveraged for back testing, decision making, forecast modelling, and risk assessment and so on. The Government dataset available in the portals (Data.gov.in) is only raw format, as the data is provided in raw format (.csv, .json etc.), it is hard to make much sense of it without pre-processing and filter. It requires some level of technical expertise to compile, filter, transform and visualize the data to make sense. In the proposed system implemented the mobile application to importing datasets from public domain sources and then plotting for user-understanding and friendly manner. As most of the goods prices move because of the supply-demand differences, the proposed Japanese candlestick charts used to predict/forecast patterns in short term and long term by capturing the change in trend using moving averages, pattern recognition methods. This forecasting model has been used in japan to forecast wheat/grain prices with high level of accuracy. As most of the Small and Medium Business owners, farmers, Traders are not so tech-savvy it become a hurdle for them to get data and interpret metrics from it. By user friendly and interactive visual charts helps them to take quick decision making, risk assessment, certainty on outcomes. Hence, the proposed mobile application of candlesticks chart gives clear picture of the product price and also easily access anytime and anywhere.
