What is Strategies?

Backtesting applies strategy rules to past data to estimate performance — subject to bias.

Formula

Backtest Process: 1. Define Strategy Rules Entry: Buy when price crosses above 20 EMA Exit: Sell when price crosses below 20 EMA Stop: 3% below entry 2. Apply to Historical Data Test period: Jan 2020 - Dec 2024 Stock: NIFTY 50 Timeframe: Daily 3. Record All Trades Trade 1: Buy ₹11,500, Sell ₹12,200 = +6.1% Trade 2: Buy ₹12,100, Stop ₹11,737 = -3.0% ... (100+ trades) 4. Calculate Metrics Win Rate: 45% Average Win: 8.2% Average Loss: 3.1% Profit Factor: 1.9 Max Drawdown: 12%

Indian market context (NSE)

Reference levels: Nifty 50 at 24,300, Reliance Industries at ₹1,300, Bank Nifty futures at 55,000 (lot size 30). Examples below show how Strategies shows up on Indian index, equity, and futures books — update to live quotes in your journal.

Nifty 50 perspective

Backtesting in Indian context at Nifty 24,300: apply SEBI/regulatory framing where relevant and tag index trades separately in weekly review.

Reliance Industries perspective

Backtesting using Reliance at ₹1,300 as a liquid large-cap example — adjust numbers to your live quote and contract note.

Bank Nifty futures perspective

Backtesting with Bank Nifty futures at 55,000 — respect lot size 30 and quarterly vs monthly contract rules on NSE.

How to validate

  • Validate Strategies only after costs — gross win rate can hide negative expectancy.
  • Use walk-forward windows (e.g. last 60 / prior 60 trades) for stability.
  • Retire or refactor the tag if Strategies expectancy turns negative with 50+ trades.
  • Ensure no overlapping tags duplicate the same trades.

How to track in TradeLyser

  • Define Strategies in Strategy Board with entry/exit/skip criteria.
  • Enforce single-tag discipline — no secondary discretionary entries.
  • Review expectancy, win rate, and avg R monthly on the tag only.
  • Archive tag version when rules change; do not blend old and new trades.

Best practices

  • One playbook page per Strategies strategy with non-negotiable rules.
  • Paper trade rule changes for two weeks before live size.
  • Track costs explicitly on high-frequency Strategies variants.
  • Compare versioned tags after each rule amendment.

Common pitfalls

  • Adding discretionary trades under the Strategies tag.
  • Scaling up after one lucky week of Strategies results.
  • Ignoring brokerage drag on high-frequency variants.
  • Retiring a tag without exporting final statistics.
