I believe tradestation has filtered data. Have u seen unfiltered data like ninja trader zen fire?

Slippage is determined by the underlying market, not by any market data. Whether the data is real time, delayed, filtered or even if you have no data at all.

Of course if you are using market orders based on 20 minute delayed quotes it may appear to be getting slippage but in reality you are not.

There is a big difference between filtered and unfiltered datas.

Yes but it makes absolutely no difference to the price you get filled at. You will be filled at the prevailing price at the exchange. Filtered data does not cause slippage though of course if you don't know the correct price you can not hope to tell. The only way to tell whether it is slippage or bad data is to use a stop order, this will let you know exactly what you slippage is without worrying about correct price data.

I'd love to learn more about this;
..about brokers better for futures than tradestation (does this make a big diff on ES and other futures too?)
...and about how it works between Ninja, Zenfire and a broker and what broker is best in this combo - I'm a little confused how this all works as opposed to a one-stop-shop like tradestation or Think-or-swim.

If anyone can shed a little light on these subjects or point me in the right direction I'd really appreciate it.
