Hi dear i do not under standing about sending on Emaile id.
Accuracy: I understand that the closing price means different things depending on the trading platform that the stock is traded on. My systems assume closing price is the last traded price not the volume weighted average price (VWAP) of the day or some other such derived rather than actual closing trade price.
Timely: The sooner I can get my hands on data the sooner I can scan the market, generate signals and enter my next day trades.
Reliable: I really want a provider that regenerates historical data based on corporate actions (mergers, splits, de-mergers, symbol changes, etc) ASAP preferably same day.
