I want to explore Tradestation or Ninjatrader for doing automated trading (I need to be totally hands off). I have a few questions to ask regular users of automated trading.

My key requirements are:

1. My model gives a buy/sell signal after the close of a day, and needs the trading to occur on subsequent data (say using VWAP or any other algo). Can I code in to Tradestation (or Ninjatrader) which can check before market open if there have been any new signal generated after the previous day's close and then automatically places a VWAP (or any other similar algo) for buy/sell? Is it possible to code instructions for VWAP trading via Easylanguage?

2. The model utilizes external third party non-price data. Can I re-code the model (currently backtested in Matlab) in Easylanguage/Tradestaton (or Ninjatrader) which can automatically check and then "upload" or somehow "read" the third party non-price data from my PC (to generate the buy/sell after the close of each day)?

3. Can the coding in Tradestation (or Ninjatrader) handle multi-security models? E.g. can the codes be written to handle pair trades? Also, can I code some portfolio construction rules in Tradestation (or Ninjatrader), for example codes to achieve "get the total current account equity" and "get the equity currently allocated in say each of the 8 equities & the cash" and then "redistribute the equity invested equally among each of the 8 equities"?

4. Finally, is it better to code in Tradestation directly or use Ninjatrader to trade via Tradestation?

I will be grateful if someone can respond.
Thanks.

(sorry for repeating the same question on platforms->brokerages! didn't realize that there is a dedicated tradestation forum.)
 
Tradestation would be recommended. Let me stress that I have no connection with either one...

The reason is that Tradestation is better suited for strategy testing and trading particularly if you are using daily signals....I have been using Ninja to autotrade and have had numerous issues with order handling. Using an ATM in Ninja Trader is more reliable, than writing code to handle orders in a Ninja Trader strategy....I also have extensive experience programming in Easy Language and Tradestation...
