I am trading within trading hours only according to this indicator. According to my trading hours I can trade EURUSD, USDCHF, sometimes USDJPY and, depends on the market condition - GBPUSD.
If you are living with the other timezone than me so you can set this indicator to your working hours. For example if you will trade on GMT night o you can trade USDJPY, AUDUSD and USDCAD.
