Price Impact

November 21, 2023 - Around 3 mins mins to read

Price impact refers to the effect that incoming orders have on the price of a traded asset. Understanding price impact is crucial in the trading world, as it can greatly influence the profitability and execution of trades.

When a buy trade occurs, it causes the price of the asset to rise. This happens because the buy trade uses up the cheapest sell orders in the order book. For example, imagine a scenario where there are sell orders at $10, $11, and $12. If a buy trade is executed at the price of $10, it will remove the $10 sell order, causing the next available sell order to be at $11. This creates a price increase.

Conversely, when a sell trade takes place, it leads to a decrease in the price of the asset. Continuing from the previous example, if a sell trade is executed at $12, it will remove the $12 sell order, causing the next available sell order to be at $11. This creates a price decrease.

The extent of the price movement resulting from trades is largely influenced by the liquidity of the trading pair involved. Liquidity refers to the ability to buy or sell an asset without causing significant price changes. Trading pairs with higher liquidity tend to have smaller price impacts compared to those with lower trading volumes.

For example, consider a highly liquid trading pair like Bitcoin (BTC) and USD. If a large buy order is executed in the BTC/USD market, the price impact is likely to be minimal because there are plenty of buy and sell orders available at various price levels. On the other hand, if the same buy order is executed in a less liquid market, such as a smaller altcoin paired with BTC, the price impact can be significant as there may be limited liquidity and fewer buy and sell orders in the order book.

Traders, especially those operating in markets with limited liquidity or those executing large trades, need to consider how their trades will impact the price of the asset. If they are not careful, they may unintentionally cause substantial price movements and potentially enter or exit positions at unfavorable prices.

It is important to note that subsequent buy trades are likely to be more expensive than the initial one due to their influence on the market. As buy orders consume the cheapest sell orders, the remaining sell orders become more expensive. This is known as slippage and is a common concern for traders executing larger orders.

Monitoring and managing price impact is a topic of great interest for trading firms. Extensive research is being conducted to understand the relationship between trade impact, trade size, and the time it takes for the impact to fully manifest in the asset price. By understanding price impact dynamics, traders can develop strategies to minimize slippage and optimize trade execution.
