Quote from Bolimomo:
1) Schwab's backend infrastructure cannot handle fast market conditions. i.e. the opening 1-5 minutes or something like 5 minute after Fed's announcement on interest rate. You place an other, then try to change the price. Waiting, waiting, waiting... nothing happen. You try to cancel the existing order, can't cancel (because confirmation is not back). This is extremely frustrating. I spoke to Schwab's tech support numerous times. They said it had to be with how their software interacts with the backend or something something (greeks to me). The bottom line is: can't change or cancel orders in fast market. This will kill you right there. I have given up on using SSPro for day to day trading. I keep it around just for kicks. (And for the few times that I really need to cancel those orders or get out a position, calling their tradedesk got busy signals. Their lines were jammed probably by hundreds of customers having the same issue.)
2) There is something weird with their charting software. My layout typically has about 15 charts opened. There are always some charts that have missing ticks, the bar not advancing, no data, or problems of that nature. When that happens you have to re-start SSPro in order to get the complete charts.
I start use the platform everyday. These problems are still current with no solution in sight.
My take: Don't use StreetSmart Pro. Get a real trading platform. Unless you only do a few trades a day and don't place orders at the opening.
