How the Bollinger Band mean reversion strategy works

Bollinger Bands put a band two standard deviations above and below a 20-period moving average. When price closes back inside the lower band after a sharp drop, the move is often stretched and may snap back to the average.

Rules

Buy when the close crosses back above the lower band.
Exit when the close reaches the middle band (SMA 20), or at a 6% stop-loss.

For a breakout version instead, buy when the close crosses above the upper band and exit below the middle band.

Backtests use historical data and simplified fills. Past performance does not guarantee future results. Education only — not investment advice.

Can I test Indian stocks, Nifty or forex?

Export the strategy as Pine Script (Pro) and paste it into TradingView’s Pine Editor. TradingView then backtests it on any symbol — Nifty, Bank Nifty, Reliance, EUR/USD, gold and more.

How are trades executed in the backtest?

Signals are checked at the close of each bar and orders are filled at that close. Stop-loss and take-profit are checked against each later bar’s high and low; if both are touched in the same bar, the stop-loss is assumed first. Fees are charged on entry and exit.

Does a good backtest mean the strategy will make money?

No. A backtest only shows how rules behaved on past data. Over-optimised rules often fail in live markets. Test on several symbols and timeframes, keep rules simple and always use risk management. This tool is for education, not investment advice.
