Really, are you that naive to how the markets work? Intenalizers - Citadel for example, give retail traders prices based off the SIP and buy/sell on direct. Whenever there's a pricing difference, it's instant risk-less profits. You can induce that pricing difference by quote stuffing.
The problem with every allegation of quote stuffing I have ever seen is that it always looks like this:
1) Blast quotes
2) ???
3) Profit
Same problem in this thread. It would be a much more convincing argument if you could spell out the actual trade.
Next time, feel free to add a </disclaimer> of some sort.
I'm not an outsider unless you've got one intense No True Scotsmen definition of the word, and I'll leave it at that. Let's just agree to disagree, and I'll say that you are certainly entitled to your opinion. Thank God, it's a free country and a free market :) Good luck.
