Hello 'NN':
I thank you for your "lesson" --- how-ever I do have some thoughts and questions.
1. From what I have been able to determine over time is that trading is more AUTO-"mated" than most realize, and "under-standing" this can change "the way" that things are "looked at" and "seen".
2. I think that most people still 'analyze' Market Maker activity based upon the old(er) PRE-AUTO-"mation" method(s).
3. When you say that: "If a stock is trading at 10 cents" --- you mean that the LAST "trade" (buy/sell) was 10 cents (be-the-cause it's like 'smoking': between "puffs", one REALLY isn't). (I'm trying to be very "technical" here for reasons which will be more apparent below.)
4. In your example of the 11,000 shares sold at 'market', does that mean that after these "trades" to accomplish it, there now RE-mains a "bid" of 4000 shares at .07? (Be-the-cause the 11,000 shares 'ate up' the 5000 @ .09, the 5000 @ .08, and 1000 of the next available 5000 @ .07)?
5. Suggestion, though: NEVER buy or sell at 'market' --- ESPECIALLY IN THE "PINKS'! The 'market' --- ESPECIALLY IN THE "PINKS' --- can be ANY 'thing' (and I've "seen" [in the past] stocks which have been trading at, say, 7 cents dropped to 1 cent for that 'sell trade' only; or raised to, say, 12 cents for that 'buy trade' only!).
6. Now, how do you "clarify" this entire PRO-cess IF there are NO 'market' buys/sells at the time?
TIA
