I've been using TradeStation for almost 2 years, now. While I have been pleased with the platform in general (albeit the lack of the ability to control it from another program), recently I have had some very negative experiences. It all started one day when I was buying up some VPHM on a big movement and I ran out of buying power mid play. Although TradeStation indicated that I had 4x buying power, in fact, I only had 1.5x. This was not indicated anywhere. I called TradeStation and was told that SOME biotechs have higher equity requirements. How much? Oh, 50% or 75%, depends. Where do they post this information? Get this... THEY DON'T! Why? Because it's an "internal policy subject to change on a daily basis." They suggested that I place "dummy trades" to determine what my REAL buying power is before entering a trade. You've got to be kidding. For active traders, this is just a silly suggestion. Who has time to be placing dummy trades just to confirm the number that they have written on the bottom of my screen?! After that, I had the same experience with PETS, "Petmed Express." I called the trading desk, and yup, 75% equity requirement. Why? "It's a biotech." WHAT?! It's specialty retail, but their brilliant credit desk labeled it as a biotech because it's got "med" in the name. Go figure. So recently, TZOO and EZPW are moving around. EZPW isn't marginable, and TZOO's equity requirements are high. I called about EZPW... "It's not marginable." Why? "Because it's been volatile lately." volatile? Ummm, ok, sure. I'm a day trader and I prefer to play those stocks that don't move. I mean, why not? Safe for TradeStation because I'm still paying commissions without risking my margin... OF COURSE I WANT TO TRADE volatile STOCKS! I am an active trader, making on average 4 position trades per day. So far this year I have paid TradeStation almost $5k in commissions. Yet, now, on practically a daily basis, I find a position I would like to trade only to find that AFTER I begin to enter the position that my margin has been reduced on that particular issue. TradeStation has shown several times that they are more concerned with risk mitigation of their offered margin than they are for their customers. They are willing to pull the rug right out from under you by cutting your margin without telling you. When it was pointed out that this was unacceptable, their representative explained that they would have to carefully weigh the benefits of providing equity requirement information to their customers with the cost of implementation. Even a web page with a listing of non-standard equity requirements would require "careful consideration." Have others experienced such frustration with their deep-discount brokerage? Is there another firm that has more regard for their customers than TradeStation? That does not handicap their customers so? TradeStation tries to sell to active traders, then they pull stunts that may directly damage an active trader's performance. I've heard good things about eTrade Pro, including lower commissions and up-front indication of non-standard equity requirements. The platform isn't as nice as TradeStation, though. What about eSignal? Any recommendations? At this point, I'm sure that one of TradeStation's new "risk mitigation" issues is going to cause me to suffer a big loss... Thank you!
