Best Strategies for Automated Stock Trading

Opening Range Breakout

One of the most popular stock day trading strategies. The bot identifies the high and low of the first 30 minutes of trading, then buys a breakout above the high or shorts a breakdown below the low.

EMA Trend Following

Use a 9/21 EMA crossover on the 5-minute chart for intraday trend following. Works well on high-volume stocks like AAPL, TSLA, and SPY.
