Dear Retail Investor: Here's How Your Stop Orders Really Work
As described by Nanex LLC's Eric Scott Hunsader,
Retail stop orders await execution, typically at common price intervals (0.00, 0.25, 0.50) at the Wholesaler. Wholesalers know those price levels and can anticipate and exacerbate the downside movement to increase net profits.
How?
Wholesalers create a composite view of the Order Book (Bid/Offer at each Price Level) across all exchanges.
