Finally we are done with 20 min delayed charts. Especially in the beginning it is quite frustrating to check out your new system using delayed quotes. What if your system is trading intraday and needs up to the minute information? Most of the times while developing a trading system there is a lot of work to be done, things need to be tested and they need to be confirmed using live market data.
Every trader wants to know whether his trading ideas are working or not. Up to now you could only do it with delayed information or End of day (Eod) data. There were just no live streaming data available at no cost.
