In the Forex Market there may occur high impact news events which can affect the robot's performance. Due to this, we have developed inteligent news filter system for WallStreet Forex Robot 2.0 Evolution and WallStreet Recovery Pro 2.0 Evolution.
To start using News Filter you have to enable it in the experts advisors' settings:
- Avoid_News = true
When you activate this system you will be able to see the coming event on the info box on the chart.
When you activate News Filter it is really important to use correct GMT Offset of your broker. You have to make sure that you set the correct GMT Offset. By default AutoGMT_Offset manages GMT Offset calculation but in rare situation it is possible to have wrong GMT offset. For that reason, you will need to set GMT Offset by yourself. In such a case, you must switch AutoGMT_Offset to false and enter the correct value in ManualGMT_Offset.
Case 1: When the calculation is correct
Case 2: When the calculation is wrong
ManualGMT_Offset=2 (set here the winter GMT Offset of your broker - ALWAYS WINTER GMT OFFSET)
Another very important parameter for the calculation of GMT offset is DST_Usage. It has to be used when your broker has winter/summer time.
Case 1: Broker changes GMT offset(for ex. winter=2; summer=3)
Case 2: Broker does not change GMT offset(for ex. winter/summer=2)
You also may want to stop the robot during Medium News Events. Our expert advisors will allow you to do that. To stop trading during these news all you need to do is to set
- Include_Medium_News = true
Last but not least, one of the most flexible parts of this system is that you can set the time when the robot to stop/start trading before/after the events. Below you can find examples:
Wait_Before_News=30 (this means the robot will stop trading 30 minutes before the news)
Wait_After_News=60 (this means the robot will start trading 60 minutes after the news)
Description of the parameters for News Filter:
Avoid_News true/false - if you wish to use the news filter function, you should set Avoid_News=true
AutoGMT_Offset true/false – this parameter controls the GMT Offset calculation method. In most of the cases, the automatic GMT value is correct. However, in some cases, you may need to enter the GMT Offset by yourself. In this case, switch AutoGMT_Offset to false and enter the value you need in the ManualGMT_Offset parameter.
ManualGMT_Offset – in case you switch to AutoGMT_Offset=false, the value of this parameter should be the right GMT Offset of your broker (usually, the winter GMT offset). As well, in case you perform a backtest, you should enter here the correct GMT Offset for the historical data you use – otherwise, the backtest will be incorrect.
DST_Usage true/false – activates the automatic DST (Daylight Saving Time) correction.
Include_Medium_News true/false: if you also wish to avoid the medium impact news, you should set Include_Medium_News=true
Wait_Before_News: the number of minutes before the news event, during which trading will be switched off
Wait_After_News: the number of minutes after the news event, during which trading will be switched off
