ℹ️ Understanding Arbitrageurs: Who They Are and What They Do

Arbitrageurs trade the same asset on two different markets by opening opposite positions—one short and one long. A good arbitrage strategy involves no market risk and provides small, risk-free returns. Arbitrageurs help the market and retail traders by making prices more efficient and adding significant liquidity to the system.

• Example

Imagine a company called BlueLines whose shares trade simultaneously in London and New York. The spread between bid and ask in both markets is 20 points. If the price difference between the two markets exceeds these 20 points, an arbitrage opportunity arises.

By buying and selling the same amount of BlueLines in both markets, the trade becomes risk-free. Once both positions are open, you wait for the prices to return in sync. When they do, both positions close, locking in a risk-free profit.

🧮 Statistical Arbitrage

Statistical arbitrage is a quantitative strategy used in any financial market. It uses statistical models to spot pricing differences between related securities. This strategy relies on complex math and historical data to detect temporary price deviations. Unlike pure arbitrage, it does not guarantee risk-free profits. Instead, traders accept some probabilistic risk, expecting prices to return to their historical norms.

⚠️ Risks and Considerations

□ Technology: Arbitrage requires ultra-low latency systems, real-time data feeds, and algorithmic execution. This technological edge explains the domination of institutional traders in this field.

□ Transaction Costs and Risks: Spreads, fees, and slippage reduce profits.

□ Basis Risk: Basis risk occurs when prices do not converge as anticipated, as seen in cash-and-carry arbitrage.

□ Market Liquidity: Less liquid markets, such as certain commodities, may be susceptible to price manipulation concerns if trades have a disproportionate impact.

□ Regulation: Regulators closely monitor strategies that could create artificial market inefficiencies.

♝ Common Arbitrage Trade Strategies

Here are some well-known arbitrage strategies used when trading different financial asset classes.

(a) Cross-Broker Arbitrage Strategies in the Foreign Exchange Market

Here are two common Cross-Broker Arbitrage Strategies:

(i) Speed-Arbitrage Strategy

In this strategy, an arbitrageur uses automated software to take advantage of price differences between a slow market maker (dealing-desk) and a fast ECN broker (no-dealing-desk). Only one trade is executed on the slower broker. The trade stays open until an opposite arbitrage opportunity appears, at which point it can close for a profit.

• Requires a standard MT4 account (slow broker) and an MT4 account (fast broker)

• Your server (VPS) should be in the same data center as the slow broker

• Works well during news events or after major price breakouts

(ii) Hedging Arbitrage Strategy

Here, automated software identifies differences in spreads between two brokers. The arbitrageur opens a position on one broker and an opposite, same-sized position on the other broker. One position hedges the other. The trade remains open until an opposite arbitrage situation occurs, which can then close for a profit.

• Requires two FIX-API accounts

• Both brokers and your server must be in the same data center

👉 Note: FIX stands for Financial Information eXchange. It is a trading technology that provides faster execution, anonymity, and better liquidity.

(b) Cross-Currency or Triangular Arbitrage Strategy in the Foreign Exchange Market

Cross-currency, or triangular arbitrage, is a strategy that exploits pricing inefficiencies between Forex pairs. This advanced method uses three currency pairs and their cross rates to find differences between implied and actual market rates. Traders convert Currency A → B → C → A sequentially, aiming to end up with more of Currency A than they started with, earning a risk-free profit.

Example:

Consider three pairs: EURUSD, EURTRY, and USDTRY offered by two different brokers.

Broker-1 quotes:

• EUR/USD = 1.0000
• USD/TRY = 3.0000

From this, EUR/TRY should trade at 3.0000.

Broker-2 quotes:

• EUR/TRY = 3.0015

This difference creates an arbitrage opportunity, which can be exploited by opening opposite positions on both brokers.

(c) Arbitrage Strategies in Stocks and Commodities

Arbitrage exists in stocks and commodities, especially when a stock is listed on multiple exchanges in different countries. Commodities like gold and oil can trade at different prices across hubs due to supply-demand imbalances, transportation, or storage costs.

🏦 Equity Arbitrage Strategies:

• Statistical Arbitrage: Using quantitative models, traders detect mispricings between correlated equities or indices.

• Spatial Arbitrage: Profiting from price differences for the same stock across different exchanges.

• Merger Arbitrage: Profiting from price discrepancies during mergers and acquisitions by buying shares of the target company and shorting shares of the acquirer.

🪙 Commodity Arbitrage Strategies:

• Cash-and-Carry Arbitrage: Traders buy a commodity in the spot market, pay carrying costs, and simultaneously sell futures contracts at a higher price.

• Spatial Arbitrage: Profiting from regional price differences due to supply-demand imbalances, transportation costs, or regulations.

• Calendar Spread Arbitrage: Profiting from price discrepancies between futures contracts with different expiration dates.

(d) Cryptocurrency Arbitrage Strategies

The cryptocurrency market is very suitable for arbitrage because of its high volatility and fragmentation across many exchanges. Price differences appear due to variations in trading volume, liquidity, and geography. Research shows that large, repeatable arbitrage opportunities are often more pronounced between exchanges than within a single country.

Here are some common types of cryptocurrency arbitrage strategies.

• Spatial Arbitrage: Profits from price differences for the same cryptocurrency across different exchanges.

• Statistical Arbitrage: Uses statistical models and algorithms to identify pricing differences between related cryptocurrencies.

• Triangular Arbitrage: Exploits pricing inconsistencies between three different cryptocurrencies within the same exchange (e.g., ETHBTC, SOLBTC, SOLETH).

🏁 Tips for Avoiding Conflicts with your Broker

Arbitrage may be prohibited by your Broker. Here are some tips to avoid issues:

(i) Use more than one account for arbitrage trading.

(ii) Trade manually for at least one month before starting an automated arbitrage strategy, or use a standard Expert Advisor (robot) with the same currency pair as your arbitrage strategy.

(iii) Keep arbitrage trades to no more than 25% of your total account activity.

(iv) Ensure your broker does not have an anti-arbitrage plugin on your account.
