GOOD DAY ALL, CAN SOMEONE ASSIST ME WITH CONVERTING THIS TRADING VIEW (PINE SCRIPT) TO A MT4 SCRIPT. IT'S RELATIVELY STRAIGHT FORWARD INDICATOR THAT DISPLAYS HISTORIC VOLATILITY PREFERABLY THE VALUE SHOULD BE CHANGEABLE BUT IF NOT THE VALUE 900 CAN BE STATIC. ANY ASSISTANCE WOULD BE APPRECIATED.

BELOW IS THE TRADING VIEW SCRIPT
