Convert TradingView Script to MT5 Indicator

I need a pinescript indicator "Currency Strength Meter" below converted to an MQL5 indicator.  Straightforward request, the MT indicator must be accurate and no error. 

//@version=4
study("Correlation Hedge", shorttitle="CoH")
//len = input(200, title="Length")
len = input(200, title="Length", minval=3)
smt = input(5, title="Smoothing EMA period", minval=1)

usd = security("DXY", timeframe.period, close)

myStoch(x) =>
    200 * (x - lowest(x, len)) / (highest(x, len) - lowest(x, len)) - 100

Calc_inv(sec) =>
    base = security(sec, timeframe.period, close) / usd
    myStoch(base)
Calc_dir(sec) =>
    base = usd / security(sec, timeframe.period, close)
    myStoch(base)

sigEur = ema(Calc_inv("EURUSD"), smt)
sigUsd = ema(myStoch(usd), smt)

plot(sigUsd, title="USD", color=#ff7f00, linewidth=2)
plot(sigEur, title="EUR", color=#00ffff, linewidth=2)
