5 guides in Finabase Learn
- Backtesting basics: biases, costs and an honest SPY test How to backtest a trading rule without fooling yourself: look-ahead and survivorship bias, overfitting, costs, out-of-sample tests, and a 32-year SPY example.
- Death Cross A chart signal where the 50-day moving average crosses below the 200-day moving average, read by some as a bearish shift.
- Exponential moving average (EMA) A moving average that weights recent prices more heavily, so it reacts faster than a simple moving average of the same length.
- Golden cross A chart signal where the 50-day moving average crosses above the 200-day moving average, read by some as a bullish shift.
- Simple moving average (SMA) The plain average of the last N closing prices, recalculated each bar; the most common way to smooth a price series and read its trend.
