很好的介绍tradestation使用的文档-Firstly, we are using a non-simulated trading account for university training purposes. Thus you will not have the ability to place orders or trades into the market. However, the back-testing allows you for research purposes to see how you would have done with a strategy and what you would have made in the amount of the trade. If you try to execute a real trade, you will get an “invalid account” message. This is perfectly normal as explained above. Now you still will be able to pull up charts and take a look at the different data lines. However only Forex offer real time intra-day data for back-testing, so any symbols that you insert, you will not be able to obtain real time intra-day data for any other symbols that you insert.　Everything else will be delayed. .You can still do back-testing on charts for which you don’t have real-time data subscr iption. You can use daily, weekly or monthly charts.



Lets say, you wanted to look at Dell stock.　 This security is on the NASDAQ exchange
