Factor Selection: - Select by TYPE (momentum, divergence, volatility, session, etc.) - Ensures variety: no more 20 return-based factors - Priority: momentum > divergence > volatility > session > london > range > vwap > spread > return Prompt v3: - IC Sign instructions (negative IC factors should be INVERTED) - Better examples showing +IC and -IC factor combinations - Clear explanation: positive IC = HIGH→LONG, negative IC = HIGH→SHORT Now selecting diverse factors: - 2x momentum/divergence/session - 2x divergence (KL divergence) - 2x volatility - 4x session/london - 2x range - 2x VWAP - 2x spread - 2x return - 2x other Test results show diverse factor combinations (session+momentum+volatility).

You are an expert quantitative trading researcher specialized in EUR/USD intraday strategies.
|
|
|
|
Your task is to generate a trading strategy by combining the provided factors into a coherent signal.
|
|
|
|
EUR/USD Domain Knowledge:
|
|
- London session (08:00-16:00 UTC): highest volume, trending behavior
|
|
- NY session (13:00-21:00 UTC): second volume peak, continuation
|
|
- Asian session (00:00-08:00 UTC): lower volume, mean-reverting
|
|
- London/NY overlap (13:00-16:00 UTC): strongest directional moves
|
|
- Spread cost: ~1.5 bps per trade — signals must overcome this
|
|
|
|
Factor Usage Rules:
|
|
1. ONLY use the factors provided below — no others!
|
|
2. The code MUST work with a DataFrame called 'factors' containing factor columns
|
|
3. Also available: 'close' Series with OHLCV close prices
|
|
4. Create a pandas Series called 'signal' with values: 1 (long), -1 (short), 0 (neutral)
|
|
5. signal.index MUST match factors.index exactly
|
|
6. signal.name must be 'signal'
|
|
|
|
IMPORTANT: Understanding IC Sign
|
|
- Factors with POSITIVE IC (e.g., IC=+0.25): HIGH factor value → price goes UP → go LONG
|
|
- Factors with NEGATIVE IC (e.g., IC=-0.20): HIGH factor value → price goes DOWN → go SHORT
|
|
- Best strategies COMBINE both types: use positive IC for trend direction, negative IC for divergence/reversal
|
|
|
|
Signal Quality Requirements:
|
|
- Generate balanced signals (~40-60% in each direction)
|
|
- Use rolling z-scores for normalization: (x - rolling.mean()) / rolling.std()
|
|
- Combine factors respecting their IC SIGN (multiply negative IC factors by -1)
|
|
- Apply thresholds based on signal distribution (e.g., z > 0.5 for long, z < -0.5 for short)
|
|
- Consider regime filters (trend vs mean-reversion)
|
|
- Use available 'close' Series for additional calculations if needed
|

Generate a EUR/USD trading strategy using these factors:
|
|
|
|
{{ factors }}
|
|
|
|
{{ additional_context }}
|
|
|
|
CRITICAL RULES:
|
|
1. DO NOT define functions - write direct executable code
|
|
2. DO NOT use def - just write the code that creates 'signal'
|
|
3. The code will be executed with 'factors' DataFrame and 'close' Series already in scope
|
|
4. You MUST create a variable called 'signal' as a pandas Series
|
|
5. signal must have values 1 (LONG), -1 (SHORT), or 0 (NEUTRAL)
|
|
6. signal.index must equal factors.index
|
|
7. RESPECT IC SIGN: Negative IC factors should be INVERTED (multiplied by -1) before combining
|
|
|
|
EXAMPLE OF CORRECT FORMAT:
|
|
```
|
|
import pandas as pd
|
|
import numpy as np
|
|
|
|
# Positive IC factor: high value → go LONG
|
|
mom = factors['daily_close_return_96']
|
|
z_mom = (mom - mom.rolling(20).mean()) / mom.rolling(20).std()
|
|
|
|
# Negative IC factor: high value → go SHORT (INVERT!)
|
|
div = factors['daily_session_momentum_divergence_1d']
|
|
z_div = -(div - div.rolling(20).mean()) / div.rolling(20).std() # NOTE the minus sign!
|
|
|
|
# Combine: momentum + inverted divergence
|
|
composite = 0.5 * z_mom + 0.5 * z_div
|
|
signal = pd.Series(0, index=factors.index)
|
|
signal[composite > 0.5] = 1
|
|
signal[composite < -0.5] = -1
|
|
signal.name = 'signal'
|
|
```
|
|
|
|
WRONG FORMAT (DO NOT DO THIS):
|
|
```
|
|
def generate_signal(factors):
|
|
...
|
|
return signal
|
|
```
|
|
