I used to be with AOT and you could have several contracts per day and only pay one brokerage fee - not sure if any other on-line brokers have the same - still doesn't explain those trades...

Real reason for posting - I'm on Apple Mac and I can take a screen capture any old time with just a couple of button clicks - I use it all the time for market depth . But at my other job, I'm on PC and I've downloaded this software (hope the link is allowed) - you just set it up so that when it's running you hit a couple of keys (eg Command + PrintScreen) and you get a crosshair on your screen which you use to enclose the area you want a pic of. Then just paste into a Word or Excel doc.
