About the Challenge
Four strategies. One stock. Who wins?
COWLS Corner is a live paper trading experiment running on real NASDAQ market data. Every five minutes during US market hours (09:30–16:00 ET), four competing strategies independently analyse Micron Technology (MU) — one of the most volatile names in the semiconductor space — and each generates a signal: long, short, or flat.
Each strategy starts with $100,000 in virtual capital and trades exactly 100 shares per position — long or short. Every position is governed by the same risk rules: a +7% take-profit, a −3.5% stop-loss that converts to a trailing stop once a trade is +1% in profit, and a 24-hour time-stop as a final backstop. No strategy can hold more than one open position at a time.
Trend-Following
EMA Triple Crossover. Watches for EMA(9) to cross EMA(21), confirmed by EMA(50) pointing in the same direction. Catches strong directional moves; struggles in sideways markets.
Mean-Reversion
RSI + Bollinger Bands. Buys when RSI < 30 and price closes below the lower band; sells short into overbought extremes. Profits from mean reversion in choppy, ranging conditions.
Momentum
MACD + Volume. Triggers on MACD crossovers only when volume confirms the move — current volume must exceed 1.5× its 20-bar average. Fewer signals, potentially higher conviction.
The Reader
Cowlpane news sentiment. Reads every Micron- and semiconductor-related article on cowlpane.com, scores bullish vs bearish language, and trades when sentiment is decisively one-sided. The wild card.
All four run on the same live data, governed by identical risk rules. Positions, trades, and P&L are recorded in a database and the chart above updates automatically. Which philosophy wins over months: trend, reversion, momentum, or news sentiment?
