The general pattern behind a front running operation would look as follows:
A market participant places an order to buy or sell an asset at a specific price. These orders are often routed through an exchange.
Another market participant with access to the exchange’s order flow becomes aware of these pending orders before they are executed.
The market participant with advanced knowledge uses this information to their advantage. They quickly place their own order to buy or sell the same asset before the pending orders are executed. By doing so, they can benefit from the anticipated price movement caused by the pending orders.
If the price moves in the expected direction due to the pending orders, the front runner can profit from the price change. They can then either close their position for a gain or sell the asset to the traders who placed the pending orders, taking advantage of the price movement they anticipated.
