Writing strategies in plain English

Marketing/Content note: Initial scaffolding — expand with real, tested example prompts and the resulting strategies.

Horizon turns plain-English descriptions into precise, rule-based strategies. The clearer your description, the more accurately it translates.

Be specific about instruments and timeframe

State what you trade and on what timeframe:

On the 1-hour chart of ETH/USDT, …

Define entry and exit explicitly

Every strategy needs a clear entry and exit. Ambiguous wording produces ambiguous rules.

• ✅ "Buy when the 20-period EMA crosses above the 50-period EMA."
• ❌ "Buy when momentum looks good."

Quantify indicators and thresholds

Name the indicator and the exact threshold: "RSI below 30", "MACD line crosses above the signal line", "price breaks the 20-day high".

Include risk rules

Add stop-loss, take-profit, and position sizing so the strategy is complete. See Risk management.

Iterate

Refine wording and re-backtest until behaviour matches intent.
