PROCEDURES USED AND IMPLEMENTATION METHODOLOGIES APPLIED
implemented BVAR-TVP parameters in matlab
Kalman implementation – Kalman toolbox in matlab
Data – Bloomberg Optimization done for two parameters
out of six (due to computation constraints), rest 4 parameters best fit value is used as per recommendation in paper

IMPROVISATIONS
The BVAR TVP parameters are regressed against recent data points ( last 1 month ) instead of the entire data points .
Advantages Less Computations. Faster results. More importance to recent Trends For GBP/USD This approach gives rise to higher annualized
returns and less RMSE GBP/USD returns obtained are 41% and is better
than the 5.7% returns obtained by using the approach mentioned in paper by author.

TRADING STRATEGY
The daily excess returns over the period (t, t+1), it, from this trading strategy are
obtained as follows:
where zt= +1 for long (buy signal) FC position and zt = -1 for short (sell signal) FC

FORECASTING ACCURACY PERFORMANCE FOR GBP /USD ( 1991 – 2000)
Model RMSE LS* MSE-T ENC-T
BVAR-TVP 0.029884
Random Walk 0.049023 -0.39649 20.90143 27.9397
• RMSE obtained by BVAR-TVP model is less than random walk. Hence the prediction using this model is more accurate than a random walk model.•RMSE Less than the RMSE obtained by the Author•Returns obtained by using the trading strategy mentioned earlier are substantial, suggesting model is accurate in prediction of FX rates.
