Backtesting 101 - Can Your Idea Survive History?
Imagine you’ve cooked up a brilliant strategy. Before risking real money, you can rewind the chart, trade it bar-by-bar, and see how it would have fared. That dress rehearsal is called backtesting - and it’s a trader’s secret weapon. 🔍🕰️
Why spend time here?
- Proof over hope: Weed out shiny-object strategies before they drain your account.
- Numbers, not vibes: Know win-rate, risk-reward and drawdown ahead of time.
- Confidence boost: Hard data keeps you calm when a live trade hits a rough patch.
