I am new to this forum and this is my first post here. I day-traded the S&P in the late nineties using TradeStation, a satellite data feed, and I phoned-in orders to my broker. I quit after a few years, but I'm interested in trading again.

Question: Is there a trading platform that will allow me to enter entry orders with a condition to automatically cancel them and then enter a stop loss if filled?

For example, Buy Stop @ 1397.25, cancel if price hits 1389.50, Sell Stop @1389.50 if filled.

Yes, there are lots of trading platforms that allow to do this. Even most FOREX platforms will include that feature. You could try

-> NinjaTrader
-> MultiCharts
-> TradeStation
-> SierraChart

NinjaTrader can be downloaded for free, you can connect to the SIM feed and test it within a few minutes. MultiCharts also has a free discretionary version (I cannot use it because I am not a Facebook member).

for just that type of application. You also may want to look at the broker MB Trading as they have some reasonably sophisticated order types that can be used lots of different ways. MB also will give you a free look, BUT make sure that if you integrate those two that you will retain the functionality you desire. DB

Not anymore. They cancelled that and removed it entirely from their site.
