I do not have a brokerage or data feed source as shown in the list above, please ask one of your participating brokerage partners to arrange a 2-Week Free Real-Time Data Trial for me. so you have to pay for a datafeed with ninja? http://www.ninjatrader.com/web/download_trading_software.htm
windsorphd if you do not have brokerage acct# and datafeed, how do you plan or get your trading signals ? Without spending a penny if you want to paper trade then best is get a paper/excel and input your entries and exits. Make sure to be more realistic only consider you got into the trade if price goes 1 tick beyond your entry / exit price, this way your are guarenteed that you will get the same fill in real market if that market is liquid( good volume ).
You could use it in sim mode. I think it is choice number 3. Also get E signal and then ask fellow traders to supply you with historical data. This way you could play with real market data from let's say last month. I say that is better than nothing and a good way to get your feet wet. Good Luck!!!!!!!!
