Forecast Scaling
Formula Base
Scaled Forecast = Raw Forecast × Scalar
Obiettivo: Average absolute forecast = 10
Calcolo Scalar
Scalar = 10 / Average(|Raw Forecast|)
Forecast Range
Dopo scaling: - Target average: ±10 - Weak signal: ±5 - Strong signal: ±15 - Maximum cap: ±20
Position from Forecast
Position = Base Position × (Forecast / 10)
Dove Base Position e calcolata per forecast = 10.
Esempio EWMAC 16/64
Step 1 - Raw forecast:
Raw = (EWMA_fast - EWMA_slow) / Daily Price Std
Step 2 - Calculate scalar (backtest):
Average |Raw| = 6.4
Scalar = 10 / 6.4 = 1.5625
Step 3 - Apply:
Forecast = Raw × 1.5625
Capped a ±20.
Forecast Combination
Con multiple rules:
Combined = (w1×F1 + w2×F2 + ...) / (w1 + w2 + ...)
FDM adjustment:
Final = Combined × FDM
Dove FDM = Forecast Diversification Multiplier.
