FAQ
How many stocks do you cover?
Does this Application provide real-time data?
Yes, DataMelon PRO provides real-time stock data including price, volume, technical indicators, financials (income statement, balance sheet, cash flow), earnings, key statistics, news, 5 day's intraday data (5-minute intervals), and up to five years of historical daily market data. ALL historical data above 5 years will be provided as monthly data. The monthly volume is the sum of the entire month volume. The daily and monthly price data is adjusted to remove gaps caused by stock splits, dividends and distributions. That may cause our charts to look different from other services that do not perform the same adjustments. Therefore, some blue chip companies may have very low adjusted prices in the early trading days.
How do you use the stock evaluation function?
The stock evaluation function calculates a percentile ranking of a stock through comparing it with all stocks and its sector across 20 selected key statistics such as PE Ratio, Dividend Yield, Profit Margin, and ReturnOnAssetsTTM. To began, look up and select a stock through the search bar. Using the slider, the weight of each key statistic can be changed. You can switch the key off to remove it from the evaluation. The resulting score is split into two sections. The first section compares the select stock with all stocks, while the second section compares the select stock with its sector. If the stock does not belong to any sector, the second section will be empty. You can make a screenshot of the evaluation result and share to other apps. Currently, the evaluation function is not available for tickers trading on Bombay Stock Exchange (BSE).
