IMO, the Amex market maker system is as corrupt as any exchange, including the TSX-V. The Amex reminds us oldtimers of the ancient OTC whereby the market makers only committed to 100 share bids/offers but could see every trade coming in and take advantage of it by allowing the stock price to fall or rise before transacting the trade of the innocent buyer/seller. This is why you see so many 100 share transactions on Stockwatch. The "Book" is never disclosed to the buyers or sellers on AMEX. Personally, I cannot wait until AUMN is large enough to trade on the NYSE where the corrupt market maker is essentially removed and trades between buyers and sellers are directly transacted.
Despite my disgust at the AMEX market makers, I don't believe they are collectively behind the $9.40 technical "prevention." I attribute that effort to the even-more-crooked naked and official shorts.
