An expert advisor from a pine script

I am seeking help writing an MQL4 EA based off a pine script strategy I made.

//@version=4

strategy("VWAP Strategy", overlay=false)

// === VWAP===

plot(vwap, color=color.white, title="vwap")

// === RSI Bar Color ===

sources = close, lengths = input(14, minval=1, title="Length")

upward = rma(max(change(sources), 0), lengths)

downward = rma(-min(change(sources), 0), lengths)

rsi = downward == 0 ? 100 : upward == 0 ? 0 : 100 - (100 / (1 + upward / downward))

src1 = close, len1 = input(55, minval=1, title="UpLevel")

src2 = close, len2 = input(45, minval=1, title="DownLevel")

isup() => rsi > len1

isdown() => rsi < len2

barcolor(isup() ? color.blue : isdown() ? color.yellow : na )

// === Tillson 3 ===

length1 = input(8, "T3 Length")

a1 = input(0.7, "Volume Factor")

e1 = ema(close, length1)

e2 = ema(e1, length1)

e3 = ema(e2, length1)

e4 = ema(e3, length1)

e5 = ema(e4, length1)

e6 = ema(e5, length1)

c1 = -a1 * a1 * a1

c2 = 3 * a1 * a1 + 3 * a1 * a1 * a1

c3 = -6 * a1 * a1 - 3 * a1 - 3 * a1 * a1 * a1

c4 = 1 + 3 * a1 + a1 * a1 * a1 + 3 * a1 * a1

T3 = c1 * e6 + c2 * e5 + c3 * e4 + c4 * e3

col1 = T3 > T3[1]

col3 = T3 < T3[1]

color_1 = col1 ? color.green : col3 ? color.red : color.yellow

plot(T3, color=color_1, linewidth=3, title="T3")

// === STRATEGY RELATED INPUTS ===

tradeInvert     = input(defval = false, title = "Invert Trade Direction?")

// the risk management inputs

inpTakeProfit   = input(defval = 200, title = "Take Profit", minval = 0)

inpStopLoss     = input(defval = 500, title = "Stop Loss", minval = 0)

inpTrailStop    = input(defval = 0, title = "Trailing Stop Loss", minval = 0)

inpTrailOffset  = input(defval = 0, title = "Trailing Stop Loss Offset", minval = 0)

// === RISK MANAGEMENT VALUE PREP ===

// if an input is less than 1, assuming not wanted so we assign 'na' value to disable it.

useTakeProfit   = inpTakeProfit  >= 1 ? inpTakeProfit  : na

useStopLoss     = inpStopLoss    >= 1 ? inpStopLoss    : na

useTrailStop    = inpTrailStop   >= 1 ? inpTrailStop   : na

useTrailOffset  = inpTrailOffset >= 1 ? inpTrailOffset : na

// === STRATEGY RISK MANAGEMENT EXECUTION ===

// finally, make use of all the earlier values we got prepped

strategy.exit("Exit BUY", from_entry = "BUY", profit = useTakeProfit, loss = useStopLoss, trail_points = useTrailStop, trail_offset = useTrailOffset)

strategy.exit("Exit SELL", from_entry = "SELL", profit = useTakeProfit, loss = useStopLoss, trail_points = useTrailStop, trail_offset = useTrailOffset)

longCondition = (close>vwap) and (vwap > vwap[1]) and (T3 > T3[1]) and (isup())

if (longCondition)

    strategy.entry("BUY", strategy.long)

shortCondition = (close<vwap) and (vwap < vwap[1]) and (T3 < T3[1]) and (isdown())

if (shortCondition)

    strategy.entry("SELL", strategy.short)
