Convert a Tradingview Pinescript into MT4 indicator

Hi,

I want to convert a Tradingview Pinescript study based on Kijun-Sen into MT4 .I have the code in Pinescript (about 15 lines of code in PS), it just needs converting to MT4. Also can you do on-screen alerts, or sound alerts for MT4 based on this indicator? If it works, I might need to add capability to auto-trade once I back-test it on MT4 later .

//@version=4
study("Kijun-PA Cross", shorttitle="K-PA X", overlay=true)

donchian(src_low, src_high, len) =>
    avg(lowest(src_low, len), highest(src_high, len))

candle_oc = input(defval=false, title="Use Candle Open/Close instead of High/Low for Kijun")
src_low = candle_oc ? min(open, close) : low
src_high = candle_oc ? max(open, close) : high
ki_Length = input(34, minval=1)
ki_baseLine = donchian(src_low, src_high, ki_Length)

long = close > ki_baseLine
short = close < ki_baseLine

kjuncol = long ? color.aqua : color.purple

plot(ki_baseLine, color=kjuncol, linewidth=1, title="Kijun-sen")

alertcondition(long, title='PA crosses Kijun-sen LONG', message='PA crosses UP Kijun-sen LONG')
alertcondition(short, title='PA crosses Kijun-sen SHORT', message='PA crosses DOWN Kijun-sen SHORT')
