I just ordered it to my eSignal and want to know if it is worth learning. Is it possible for market depth to give me a better "edge" in the markets? If so, how would you say?
If your scalping for a few ticks it may be worth while. Personally I do better, particularly when trying to catch intraday swings, when I don't look at it. You might try the search function in the upper RH corner of your browser. There have been some good threads on the topic.
You might find this thread interesting. I went to looking for it and realized it was harder to find than I thought, and I knew what I was looking for. http://www.elitetrader.com/vb/showthread.php?s=&threadid=42947&perpage=6&pagenumber=1
