If I am doing option research at Fidelity or Schwab...Are they selling the information to someone??

IMO, STOP orders often get "bad" fills because the price you pick is often a support or resistance point and there can be a large number of short term traders do the same. The Market Makers, often the only liquidity, pull their bids when there is a large supply, until it settles. No one is hunting you. Would you post large bids if you see 5000 market orders hitting you all at once? Not 5000 shares, but 5000 orders. Or, would you scale down?

Robert popping conspiracy bubbles,.. "...but..but they hunted my stop!"

Occam's Razor for the logic that would be lost on most.

On a technical level we're talking specialized infrastructure and software beyond level 2 data available to retail, yes?

Maybe that is what your thinking, I'm not.

Let me rephrase for clarity.

MM’s have access to specialized infrastructure, data and software not available to retail, correct?

This is distinct from the concept of MM’s not participating when market conditions are not favorable to their profitability, yes?

Fun fact: (but different topic) That's how the Captcha determines if you are a human or not; by tracking the randomness of the mouse pointer path moving across the screen as you play their games training their Ai.

you think captchas can track what you're doing on your local computer? they somehow login? are captchas a virus?

Robots are very methodical, so it is easy to determine by the behavior. Humans would most likely not click directly in the middle but in some other area of the box. This method has been incredibly accurate, thanks to Google. If this first test fails, there is a backup where the user will then be asked to type some combination of numbers or letters.
