Snapshots

Backtest on OANDA:SPX500USD 4h (2013 to Sep 2026): 427 trades, 43.8% winners, profit factor 0.953, total P&L -$112.

List of trades: every entry and exit with its profit or loss.

Strategy properties: capital, order size, 0.05% commission, 2 ticks slippage, on-bar-close execution.

The complete strategy in the Pine Editor.

How it works

Honest result: about +$298 before costs, but ~$411 of commission turned it into a -$112 loss. Test costs before you trust any backtest.
Each trade risks 2 ATR (stop) to make 3 ATR (target), sized at 10% of equity.
For automation, create a strategy alert and put {{strategy.order.alert_message}} in the message box; your webhook receives {"side":"buy","symbol":"SPX500USD"}.
