The Parabolic SAR Indicator is controlled by the acceleration factor that is comprised of two variables: the Step (Acceleration Factor) and the Maximum Step. This indicator uses the PSAR (inbuilt) indicator and returns two strength scores (2 lines in window) - one for the base currency and other for counter currency.It combines the group of correlated (base & counter) currency pairs dynamically from the chart, as per:

• AUD="AUDUSD","AUDCAD","AUDCHF","AUDJPY","AUDNZD" / "EURAUD","GBPAUD"
• USD="USDJPY","USDCHF","USDCAD","USDNOK","USDSEK" / "AUDUSD","NZDUSD","EURUSD","GBPUSD"
• NZD="NZDCAD","NZDCHF","NZDJPY","NZDUSD" /  "AUDNZD","EURNZD","GBPNZD"
• GBP="GBPUSD","GBPAUD","GBPNZD","GBPCAD","GBPCHF","GBPJPY","GBPSEK","GBPNOK" / "EURGBP"
• EUR="EURUSD","EURAUD","EURNZD","EURCAD","EURCHF","EURGBP","EURJPY","EURSEK","EURNOK"
• CHF="CHFJPY" / "EURCHF","USDCHF","AUDCHF","NZDCHF","GBPCHF","CADCHF"
