Basic Knowledge for Algo Trading
To get started, focus on these core areas:

1. Financial Markets Basics

Understand asset classes (stocks, forex, crypto, futures).
Learn about order types (market, limit, stop-loss).
Know key market indicators (moving averages, RSI, MACD).

1. Programming Skills

Python (most popular for algo trading).
Basics of data structures, APIs, and libraries like pandas, numpy, backtrader, and zipline.

1. Quantitative Analysis

Statistical concepts (mean, variance, correlation).
Time series analysis.
Basic machine learning (regression, classification).

1. Trading Platforms & APIs

How to connect to brokers (Interactive Brokers, Binance, etc.).
Using REST and WebSocket APIs for real-time data.

1. Backtesting & Risk Management

How to test strategies on historical data.
Risk metrics (Sharpe ratio, drawdown, volatility).
Basic Algo Trading Code Snippets

1. Fetching Stock Data (Using yfinance)

import yfinance as yf

# Download historical data for Apple
data = yf.download("AAPL", start="2023-01-01", end="2023-12-31")
print(data.head())

1. Simple Moving Average Crossover Strategy

import pandas as pd

# Calculate moving averages
data['SMA_50'] = data['Close'].rolling(window=50).mean()
data['SMA_200'] = data['Close'].rolling(window=200).mean()

# Generate signals
data['Signal'] = 0
data['Signal'][50:] = np.where(data['SMA_50'][50:] > data['SMA_200'][50:], 1, 0)

# Plot
import matplotlib.pyplot as plt
plt.plot(data['Close'], label='Price')
plt.plot(data['SMA_50'], label='SMA 50')
plt.plot(data['SMA_200'], label='SMA 200')
plt.legend()
plt.show()

1. Backtesting with Backtrader

import backtrader as bt

class SmaCross(bt.Strategy):
    params = (('fast', 50), ('slow', 200))

    def __init__(self):
        sma_fast = bt.indicators.SMA(period=self.p.fast)
        sma_slow = bt.indicators.SMA(period=self.p.slow)
        self.crossover = bt.indicators.CrossOver(sma_fast, sma_slow)

    def next(self):
        if not self.position:
            if self.crossover > 0:
                self.buy()
        elif self.crossover < 0:
            self.close()

# Run backtest
cerebro = bt.Cerebro()
data = bt.feeds.PandasData(dataname=data)
cerebro.adddata(data)
cerebro.addstrategy(SmaCross)
cerebro.run()
cerebro.plot()
