I do not believe in MM signals.
But, that trade was certainly an outlier. My nephew worked as a broker and said that MM signals, as discussed by OTC/Pink stock boards and chat rooms, are urban legends. He was very friendly with the market makers in the back rooms.
- It is possible for market makers to steer sales and buys to another specific MM.
- Sometimes, someone stupid puts in an online Sell at Market, with no limit, and they get caught.
- Market makers will almost never show their hand to let others know what order they are working.
- Using smaller bids and some patience will usually mean an MM can buy shares a bit cheaper.
- MMs will put up 100-200 shares to see if the fish are biting.
- They will then remember who sold or bought.
- Those working on the floor have hand signals, but that does not apply to OTC and Pink stocks.
But, the 100, 200, 300 share MM signalling, famous on the OTC/Pink boards, is urban legend.
