// Strategy based on the Follow Line Indicator by Dreadblitz, Hull Suite by InSilico and Range Filter Buy and Sell 5 min by guikroth
// Designed for the purpose of back testing
// Strategy:
//  - When the Range Filter Color Changes, And the HULL Suite is in that direction, Enter In that direction
//  - e.g Range Filter Changes color from red to green, and Hull Suite is in Green. Enter Long
//  - e.g Range Filter Changes color from green to red, and Hull Suite is in red. Enter Short
//
