Layering, also known as spoofing, is a form of market manipulation in which traders submit orders at particular price levels to influence the price of an underlying asset. For example, if a trader wants to sell at a higher price than the asset is currently trading for, he or she may do so by placing a buy order above the current price. The price might move up a bit as a result. However, because the order was never meant to be fulfilled, the trader cancels it; instead, it was intended to raise the price further. Now, the trader may sell their position at a higher price.
