Gary,
With Fido, I only pay $14.95 commission. You should ask them about that. You could probably get it, too. I have a Spartan Gold Circle account, but I believe they relaxed their requirements a few months ago. I use, CyberTrader, by the way, but I am sure MBT is just as good also.
Regarding, DBC Signal, I used them last year. But these other brokers we have mentioned allow you to execute directly from your quote screen and don't charge you for quotes if you meet a minimum level. I got rid of Signal a long time ago and never regretted it. In fact, AT-Financial has a better system than DBC/Signal, imho. Only thing I liked about Signal was that it keep good track of your portfolio in realtime. But you can do much better!
