What is a Bid-Ask Spread in Crypto?

When you engage in buying and selling assets on a crypto exchange, the prevailing market prices are determined by the forces of supply and demand. 

In addition to the price, it is crucial to consider other essential factors such as trading volume, market liquidity, and order types. However, it is important to note that depending on the prevailing market conditions and the type of orders used, you may not always obtain the desired price for a trade.

The process of buying and selling assets on a crypto exchange involves a continuous bargaining between buyers and sellers, which results in a spread between the bid and ask sides (bid-ask spread). Depending on the volatility of the asset being traded and the amount involved, you may also encounter slippage. Therefore, having a basic understanding of the order book of an exchange is vital to avoid any unexpected outcomes.

What is a Bid-Ask Spread in Crypto?

In simple terms, the bid-ask spread refers to the difference between the highest price that a buyer is willing to pay for a certain digital asset and the lowest price that a seller is willing to sell it for. This difference in price is what makes up the bid-ask spread.

Assume that the current market price of a particular asset is $100. A buyer is willing to buy the asset for $95, and a seller is willing to sell it for $105. In this situation, the bid-ask spread is $10, which is the difference between the highest bid and the lowest ask price.

The bid-ask spread can be seen as the transactional cost involved in buying or selling an asset in the crypto market. The wider the bid-ask spread, the more costly it is to buy or sell a particular digital asset.

Crypto exchanges, which act as intermediaries between buyers and sellers, make their profit by taking a commission on each transaction. This commission is usually taken as a percentage of the bid-ask spread.

The bid-ask spread can vary depending on a number of factors, such as the liquidity of the asset, the trading volume, and market volatility. Highly liquid assets such as Bitcoin and Ethereum usually have a lower bid-ask spread as there are more buyers and sellers, resulting in a more efficient market.

It's important to note that the bid-ask spread can change rapidly in response to market conditions. During periods of high volatility, the bid-ask spread can widen as buyers and sellers adjust their prices to the rapidly changing market conditions.

Market Makers and Bid-Ask Spread in Crypto

Market makers play a critical role in ensuring that there is enough liquidity in the market. In crypto markets, market makers are usually crypto exchanges, but they can also be specialized firms that focus solely on market making activities.

The primary role of market makers is to provide liquidity and create a market for trading cryptocurrencies. Market makers achieve this by providing two-way quotes for an asset at all times, thereby allowing buyers and sellers to execute trades without delay. They earn profits by buying at the bid price and selling at the ask price, pocketing the difference as their commission. The wider the bid-ask spread, the greater the potential profit for market makers.

However, market makers also take on significant risks, as they are exposed to potential losses if market conditions change rapidly. For instance, if a market maker buys a large volume of an asset at a low price and the market price suddenly drops, the market maker could be left holding a significant amount of assets worth less than what they paid for them.

Market makers can use a variety of strategies to mitigate these risks, including setting limit orders and hedging their positions. They can also adjust their bid and ask prices to reflect changes in market conditions and trading volume, thereby ensuring that there is always enough liquidity to facilitate trades.

Possible Market Maker Manipulation

Market makers play an important role in maintaining liquidity and narrowing bid-ask spreads in the cryptocurrency market. However, in some cases, market makers can manipulate bid-ask spreads to their advantage, potentially cheating traders.

One way market makers can cheat with bid-ask spreads is through quote stuffing. This involves placing a high volume of orders with the intention of creating an illusion of high demand or supply. This can trick traders into making decisions based on false market conditions, allowing market makers to profit from the spread.

Another method used by market makers is spoofing, which involves placing fake buy or sell orders in the order book to manipulate the market. By placing large orders that they have no intention of filling, market makers can create a false sense of demand or supply, which can cause traders to buy or sell at less favorable prices.

Finally, market makers can also engage in front-running, which involves using non-public information to make trades ahead of other traders. By doing so, market makers can manipulate prices and bid-ask spreads to their advantage, making profits at the expense of other traders.

It is worth noting that such manipulations are illegal and can result in severe penalties for the market makers. As such, reputable exchanges take measures to prevent such activities and ensure a fair trading environment for all market participants.

Slippage and Bid-Ask Spread in Crypto Trading

Slippage is a term used to describe the difference between the expected price of an asset and the actual price at which it is traded. It can occur due to a variety of factors, including market volatility, trading volume, and the bid-ask spread.

When a trader places a market order to buy or sell an asset, they will usually receive the best available price at the time the order is executed. However, if the bid-ask spread is wide, the trader may end up paying a higher price when buying or receiving a lower price when selling than they had anticipated.

This difference between the expected and actual price is known as slippage. Slippage can occur in both bullish and bearish market conditions and is especially prevalent in highly volatile markets, such as the cryptocurrency market.

Traders can mitigate the risk of slippage by using limit orders instead of market orders. A limit order is an order to buy or sell an asset at a specific price or better. By setting a limit order, traders can ensure that they are only buying or selling an asset at the price they are willing to pay or receive, respectively.

It is important to note that slippage can also occur due to market conditions that are beyond a trader's control. For instance, if there is a sudden surge in trading volume, it can result in a shortage of available liquidity, causing the price to move rapidly and unexpectedly. In such cases, even limit orders may not be able to protect traders from experiencing slippage.

However, slippage does not always lead to a worse-than-expected price outcome. In fact, positive slippage can occur when the price of an asset decreases during a buy order or increases during a sell order. While positive slippage is not common, it may happen in highly volatile markets.

Bid-Ask Spread Percentage

The bid-ask spread percentage is a common measure of liquidity in the financial markets, including the crypto market. It is calculated by dividing the difference between the highest bid and the lowest ask price by the mid-price (the average of the highest bid and lowest ask prices) and multiplying the result by 100. The resulting percentage indicates the percentage difference between the bid and ask prices.

The wider the bid-ask spread percentage, the less liquid the market is considered to be, as there are fewer market participants willing to buy or sell at the current price. Conversely, a narrow bid-ask spread percentage indicates a more liquid market, with more buyers and sellers actively trading at or near the current price.

Therefore, understanding the bid-ask spread percentage is crucial for traders and investors to assess the market's liquidity and make informed trading decisions.
