How to read this — and what it can’t tell you.
Prices are split- and dividend-adjusted, so “buy & hold” reflects the real total return.
Signals are read at each day’s close and the trade fills at the next day’s open — no cheating with prices you couldn’t have known.
Every buy and sell pays a 0.05% cost (spread + slippage). Real results vary by broker.
This is one stock, fully in or fully out — not a diversified portfolio, and it ignores taxes.
The past is not the future. A rule that worked on one stock’s history can fail going forward. This tool is for learning, not financial advice.
