💡 Pro Tips

📈 Trend Following

"The trend is your friend until the end." Don't fight momentum, but have exit strategy ready.

🎲 Diversification

Never put all capital in one prediction. Spread risk across uncorrelated assets.

⚡ Volatility Clusters

Big moves follow big moves. Adjust position sizes when volatility increases.

📰 News Impact

Markets often overreact to news. Fade extreme moves for mean reversion plays.

🔄 Regime Changes

Models trained on bull markets fail in bear markets. Detect regime shifts.

🛑 Stop Losses

Always define maximum loss. Better to lose 5% than watch it become 50%.
