This is interesting - I just checked out the current WindowTrader and it is identical to what is on the Photon execution software. It is the exact same product...! I don't know why they are charging so much more for the stand alone version....at least with the Photon platform you can placel trades on the charts.
it's not unusual for charting companies to create relationships with brokers (MD with OEC, QT with TDA, etc). often, they lease a white-label version to the brokers, who then rebrand the software. i'm guessing that is the case here. that being the case, they aren't charging more for their software; just like any other charting vendor, they have a standard subscription rate. if your broker offers the software and you are happy with your broker, looks like you are in a good spot hope this helps. have a great week!
THe best that I have found is from Value Zone trading. They charge a yearly subscription which is what most charge for a quarter. Runs on Ninja and Tradestation.
anything exciting happening at windotrader? I'm trying to compare them to market delta's pro package but their website is so vague and I hate talking to sales people.
