That makes sense. I don't trade in this manner (fading spoofers), but I find it interesting.re: "Regardless, I imagine you must be riveted to the screen since you get very little advance notice when to act"
if you've got custom software that scans the level 2 quotes:
1) yes you can follow more than one symbol
2) no you don't have to be glued to the screen
Based on criteria you set forth, it will flag the unusual spoofing activity and provide a summary of the frequency of it's occurrence....and sort by highest frequency for all symbols to show which ones are getting spoofed the most.
