The Nasdaq trades were instantaneous and reliable, but the NYSE hitting the inside, took forever to fill. Maybe the specialist's fault on the NYSE.
I thought it was a mostly fast, reliable platform even with Comstock as the data feed.
With my IP bandwidth as the limiting factor, I would have up to 30 charts on a 3 minute scale, several L2's with Time and Sales, the snp and nas futures, an account window, and a few EYES windows. The charts have various diagnostic and analytical tools already programmed into the tool bar, and one of my favorites was the fibonacci retracement lines. Charts can be set up to link to L2 windows easily. The L2 windows have an easy way to list your stocks of interest for that day and you can scroll through your list easily on the L2. The L2 window always shows your postion, x shares long or short, a really valuable feature.
One of the nice features was an ability to click on a chart and enter an order from there and also to enter your stoploss the same way. The hotkeys worked just great as you can structure and direct your order with any number of different keystrokes. I especially liked the limit orders plus or minus delta.
The major disadvantage was the tech support, although responsive, it was always your fault if something went wrong with the software. Didn't happen too often but the attitude stinks.
As an example, one of the downloaded software versions permitted you to enter illegal short sales on an uptick, resulting in horrendous charge backs.
As an account holder I felt that I really had to be on top of the situation myself and assume the responsibility if the software don't work like I expected it to.
I have an account with them but have not traded there for a while.
All in all, the best I have used so far. I just wished tech support took more responsiblility. I am interested in knowing if there is a better platform out there. I am looking forward to seeing what Tradestation 6 operates like with the new version out soon, with speed keys and chart linking to L2.
