Translate Pine Script (Tradingview) Indicator into MQL4

 Hi, I need the indicator vortex trend tracker translated into mt4, it needs to be 100% the same, with histogram and colors being darker when there is a clear trend signal 

mql5 doesn't let me insert the link,  but it is vortex trend tracker of profitprogrammers on tradingview

//@version=4

study("Vortex Trend Tracker")

//          INPUT VARIABLES FOR VORTEX: 

vortexLen = input(30, title="Length for Vortex", minval=1)

emaLen = input(10, title="Length of Positive and Negative EMA's", type=input.integer, minval=1)

colorBars = input(true, title="Color Price Bars Based on Vortex?")

plotVLines = input(false, title="Plot VI+ and VI- Lines?")

//          VORTEX CALCULATION:

//Returns positive and negative trendlines. 

vortex(posSum, negSum, vLen)=>

    tRange = sum(atr(1), vLen)

    vmPlus = posSum / tRange

    vmNeg = negSum / tRange

    [vmPlus, vmNeg]

[vPlus, vNeg] = vortex(sum(abs(high - low[1]), vortexLen), sum(abs(low - high[1]), vortexLen), vortexLen)

plusEMA = ema(vPlus, emaLen)

negEMA = ema(vNeg, emaLen)

vDiff = abs(plusEMA - negEMA)

//          PLOTTING:

var color vColor = na

vColor := plusEMA > negEMA and plusEMA >= plusEMA[1] ? #1b5e20 : plusEMA > negEMA and plusEMA < plusEMA[1] ? #a5d6a7 : negEMA >= plusEMA and negEMA > negEMA[1] ? #b71c1c : negEMA > plusEMA and negEMA < negEMA[1] ? #c76a72 : nz(vColor[1])

plot(vDiff, style=plot.style_histogram, color=vColor, linewidth=3, transp=0)

plot(plotVLines ? plusEMA : na, title="VI +", color=color.green, linewidth=2)

plot(plotVLines ? negEMA : na, title="VI -", color=color.red, linewidth=2)

barcolor(colorBars ? vColor : na)
