Study Notes
Algorithmic Trading Overview
- Algorithmic trading is trading based on a defined set of rules that can be implemented on a computer.
- This strategy is used for execution, trend following, arbitrage, and market making.
Execution
- The challenge in execution is to fulfill a large order without causing market fluctuations.
- It involves dividing a large order into smaller ones and executing these gradually.
- TWAP (Time Weighted Average Price) is an example of an execution strategy.
TWAP (Time Weighted Average Price) Formula
- The formula for TWAP is: $$ V_{TWAP} = \frac{\sum_{i=1}^{n}V_i}{n} $$
- $V_i$ represents the volume traded in period i.
- n stands for the number of periods.
Trend Following
- Trend following is designed to identify and capitalize on market trends.
- Technical indicators are used to spot trends, and trades are made in the trend's direction.
- A moving average crossover is an example of a trend-following strategy.
Moving Average Crossover
- It functions by calculating short-term and long-term moving averages of the price.
- A buy signal is generated when the short-term average crosses above the long-term average.
- A sell signal occurs when the short-term average crosses below the long-term average.
Arbitrage
- Arbitrage aims to profit from price discrepancies in different markets.
- It involves buying an asset in a market where it is cheaper and selling it where it is more expensive.
- Triangular arbitrage is provided as an example.
Triangular Arbitrage
- It involves identifying three assets where the cross-rate between two differs from the price of the third.
- An example scenario involves currency conversions: $1 to £0.8, £1 to ¥130, and $1 to ¥120.
- Example trade (this example is not profitable):
- Sell $10,000 to buy £8,000
- Sell £8,000 to buy ¥1,040,000
- Sell ¥1,040,000 to buy $8,666.67
- Profit (in example): -$10,000 + $8,666.67 = -$1,333.33
Market Making
- Market making seeks to profit from the spread between bid and ask prices.
- This involves simultaneously posting bid and ask orders for an asset.
- A simple market-making strategy is outlined.
Simple Market Making
- It requires posting bid and ask orders at a set distance from the current price.
- Profit is generated by collecting the spread between the bid and ask prices.
Algorithmic Trading Risks
- Trading algorithms are exposed to model risk, execution risk, and data risk.
- Algorithmic trading also carries a risk of overfitting and regulatory risk.
