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

ModelRMSELS*MSE-TENC-T BVAR-TVP Random Walk 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.
