Video learning: How position sizing changes strategy results · The 10 metrics to check in a backtest.
Inputs and Properties are different
Inputs control the strategy’s entry/exit signals, filters, optimization presets and optional automation settings. Properties includes the backtest account and execution assumptions such as starting capital, position sizing, fees and slippage.
- Select the correct market feed and chart timeframe.
- Load the desired strategy version and optimization preset, if available.
- Inspect every enabled entry, filter and exit condition needed by that version.
- Check initial capital, commission, slippage, currency and order sizing under Properties.
- Run Strategy Tester and confirm that the reported trades, dates and performance assumptions match the configuration you intended.
- Save or export configuration details only after verifying they are correct; imports may not include every Properties field or may be affected by script revisions.
- After changing automation-relevant settings, recreate the TradingView alert: an alert preserves a snapshot of the script, symbol, timeframe and inputs.
Different brokers and exchanges can produce different historical fills and execution results. Never assume copied settings are risk-appropriate for another account.
